Recently, I spoke in the Senate regarding the impact of this summer’s flooding on the coral reef. Coral polyps are saltwater creatures. When floodwaters impact the reef, it introduces fresh water, cold temperatures and sediment, all of which cause coral bleaching. El Niño (ENSO cycles) causes a reduction in clouds, resulting in higher solar radiation, higher temperatures, and coral bleaching.

Both of these are cyclical and not caused by human activity. Yet the Great Barrier Reef Marine Park Authority (GBRMPA) appear to be focusing solely on the “climate change is causing warming temperatures and coral bleaching” argument instead of presenting the broader picture.

I was reassured that the GBRMPA accepts that ENSO cycles play a role in coral bleaching. I look forward to more honesty and transparency on this issue from the BOM, CSIRO and the globalist controlled Australian Institute of Marine Science.

Transcript

Senator ROBERTS: Thank you for appearing tonight. Let me start with a simple question: can floodwaters entering the reef from the 28 river systems that discharge onto the reef in a rain event, such as a tropical cyclone, cause coral bleaching, either through fresh water itself, through very low floodwater temperature, or through high nutrient levels or turbidity or sediment?

Mr Thomas: There can certainly be initial freshwater bleaching from flood events.

Mr Quincey: And we did see some of that this year with the cyclones in the north.

Senator ROBERTS: It’s true that corals also bleach from water that is too cold, isn’t it? I can remember that in June 2008 that there were record cold temperatures in various parts of Queensland and the Northern Territory, including southern Queensland, and the southern Great Barrier Reef bleached because of the cold weather.

Mr Thomas: I’m not sure of that particular example. But, yes, bleaching is certainly a stress response that can be triggered by a range of different things. Most recently, though, our biggest concerns have been about warmer waters, not colder waters.

Senator ROBERTS: Was any of the coral bleaching that was evident on the reef in the first quarter of 2024 caused by freshwater and salt intrusion?

Mr Thomas: Yes, as Mr Quincey said. Probably because of flood events prior to and post Christmas in in the north, there would have been some initial freshwater bleaching. I don’t have specific details of that in front of me, though.

Senator ROBERTS: Thank you. Was any of the coral bleaching in the first quarter caused by pesticides or other chemical run-off from farming areas?

Mr Thomas: Direct attribution of those impacts would be difficult for me to provide here today, but we could take some of that question on notice.

Senator ROBERTS: Please. According to a paper from the University of Queensland, simplified: The most devastating mass coral bleaching has occurred during El Niño events … However, El Niño itself does not cause SSTs— sea surface temperatures— to rise in all regions that experience bleaching. Nor is the upper ocean warming trend of 0.11°C per decade since 1971 … sufficient alone to exceed the thermal tolerance of corals. This paper shows that a major contributing factor is El Nino reducing cloud cover, causing ‘higher than average air temperatures and higher than average atmospheric pressures’ and playing ‘a crucial role in determining the extent and location of coral bleaching’ on the reef. Is that a fair statement?

Mr Thomas: I’m not aware of that particular paper. Did you say it was the University of Queensland?

Senator ROBERTS: Yes.

Mr Thomas: I’m not aware of it. I’m sorry. But we would be very interested to read more about it.

Senator ROBERTS: We can get it to you.

Mr Thomas: Yes, please.

Senator ROBERTS: Do you accept natural, cyclical ENSO events play a crucial role in coral bleaching?

Mr Thomas: We would have to defer to climate scientists around the particular localised impacts and how they’ve played out on the Great Barrier Reef.

Senator ROBERTS: Localised impacts, not global?

Mr Thomas: For how those significant meteorological phenomena impact the Great Barrier Reef in particular, I would need to consult with other relevant experts.

Senator ROBERTS: According to the Bureau of Meteorology document ‘124 years of Australian rainfall’, there’s no trend. There’s no pattern. It’s just cyclical. There’s no trend whatsoever, down or up. It’s just natural variation, influenced by cycles. In the last five years, we’ve had three La Ninas. Your website, under the heading ‘What causes coral bleaching?’, makes the comment: The biggest cause of coral bleaching in the past 20 years has been rising water temperatures. On notice if you wish, please provide how much water temperature has increased in the last 20 years, including average and range, showing any spikes that may have occurred.

Mr Thomas: Thank you. We will take that on notice.

Senator ROBERTS: Something like that, maybe?

Mr Thomas: I’m not sure I can reproduce that exactly, but we’ll certainly take that—

Senator ROBERTS: No, I wouldn’t expect you to reproduce it.

Mr Thomas: We will certainly try to take an—

Senator ROBERTS: Thank you. Have you tested those spike temperatures that may have led to bleaching against the ENSO cycle? Have you correlated them?

Mr Quincey: I couldn’t answer now, but we would most likely consult with our colleagues not only in the Bureau of Meteorology but in the CSIRO and the Australian Institute of Marine Science, who do some of that work.

Mr Thomas: We’re not the authors of some of these reports. We work with those relevant institutions. We pull that information together. We try to synthesise it and make the best assessments we can on how we can hone our programs and better manage the Great Barrier Reef into the future. With some of the specificity and science you’re referring to, we really would need to speak to some of our experts.

Senator ROBERTS: Okay. This is the last question. The bleaching impact statement on your website, which you describe as ‘a framework to describe and categorise coral bleaching on the Great Barrier Reef’, only includes one factor: heat stress, which you attribute to climate change, ignoring these other crucially important factors. Is this about blaming bleaching on climate change, which is well-funded, and ignoring the role of natural cycles, which carries no funding? We’ve heard the United Nations say that the planet is now boiling.

Mr Thomas: Is your question about whether our framework for understanding coral bleaching is limited to heat stress?

Senator ROBERTS: Yes, it seems that it’s only limited to heat stress.

Mr Quincey: It has it there as heat stress, but the exposure blocks the subtleties of exactly what you’re talking about—about light intensity and exposure and cloud cover. Also, on our website, we really try to convey that local and regional weather in particular places has a large bearing on the outcomes that we see each summer, and those factors play into that.

Senator ROBERTS: Thank you.

When discussing coral bleaching, the assumption these days immediately defaults to blaming mythical “climate change” instead of looking for the real cause.

There are many causes of bleaching, including changes in salinity, UV radiation, sedimentation, and pollution. Coral bleaching is a response to environmental stress, not just temperature fluctuation.

Studies have shown evidence of bleaching dating back centuries, long before any “claimed” influence on the weather was caused by humans. Coral has shown resilience and adaptability to different conditions and reefs have recovered from bleaching events for millennia.

It’s time the climate carpetbaggers were called out for their selective pseudo-science that is designed to protect their taxpayer funding. It’s time to recognise the resilience of our coral reefs and bring the tourists back to Queensland.

When discussing coral bleaching recently, the assumption defaults to blaming claimed human climate change instead of asking what actually caused it. Coral bleaching in simple terms is a loss of colour in coral, most often due to symbiosis dysfunction, a severing of the join between the coral polyp and the host tissue—the calcium carbonate that gives coral its white colour. Bleaching is a response to environmental stress. It has many causes, including changes in salinity, ultraviolet radiation, increased sedimentation and high nutrient levels after flooding or pollution.

Kamenos from the University of Glasgow found evidence of Great Barrier Reef bleaching in the 1600s. His paper has been contested, yet the many citations used to support his paper have not been. Hendy documented two hiatuses in coral skeleton growth, associated tissue death and subsequent regrowth in eight multicentury coral cores collected from the central Great Barrier Reef accurately dated to 1782 to 1817. This period was before humans are claimed to have influenced the weather.

Dunne recorded bleaching on the reef in 1928. Woolridge documented the bleaching caused by floodwaters carrying nutrients impacting on the reef. Kenkel found coral has plasticity to adapt to different environmental conditions and is more resilient than previously thought. Maynard found that coral adapts to bleaching by becoming more resilient. During the past 2.5 million years, there have been 40 glacial maximums and 40 interglacial periods. Eighty times, coral has had to rise or fall by up to 140 metres, and our coral reefs are still there. How resilient they are. 

Our reefs have been subjected to bleaching for millennia, and they always recover, as they did in 2022, when the Greens were telling us the reef was dead, and tourists believed them. Tourist numbers are below the long-term average, COVID excluded.

It’s time climate carpetbaggers were called out for selective pseudoscience designed to protect their taxpayer funding. Bleaching is a part of nature. It recovers. It’s cyclical. 

I spoke on Green Senator Whish-Wilson’s motion that the Great Barrier Reef is dying — again. This fear-mongering is used to justify the exorbitant amount of money being transferred from hardworking Australians to parasitic billionaires promising to “fix” the climate. Coral bleaching on the Great Barrier Reef is a natural cycle. Media and politicians are exaggerating the extent of damage to the reef and in so doing, they are causing economic harm to businesses that rely on tourism for their survival.

Human civilisation and the environment are not mutually exclusive and industrial progress, supported by hydrocarbon fuels, has actually benefited the environment by reducing reliance on resources like whale oil and timber. If the Greens want a real environmental cause, they should campaign against the wind turbines that are being built across northern Queensland, which involves blowing the tops off mountains and permanently destroying the natural environment.

This is more than just aesthetics. Green energy is creating sediment that is full of arsenic, which has been locked away in the rocks for millennia. This runoff flows through underground aquifers and ends up in the ocean, poisoning the reef. The Greens are silent on this vandalism to our natural environment and make up rubbish stories about the reef so that they can “pretend” they are an environmental party.

One Nation protects the natural environment – Greens destroy it!

Once again those who worship the sky god of global boiling are using their religion to scare the public into holding the line on the great climate boiling scam. Is it still global boiling or have we now moved to global scalding? This fearmongering, this scaring, as I’ve been explaining for many years, involves taking money from hardworking Australians and giving it to parasitic billionaires to fix the climate. 

Senator Whish-Wilson’s latest motion reheats an old, debunked scare: the Great Barrier Reef is dying. In 2016 the Washington Post ran an article titled ‘”And then we wept”: Scientists say 93 percent of the Great Barrier Reef now bleached’. In 2022 the Washington Post ran an article titled, in part, ‘Great Barrier Reef has the most coral in decades’. In 2024 they ran an article titled ‘Fatal heatwave strikes unspoiled swath of Great Barrier Reef’. It went on to say: 

Water temperature data suggests the toll of this event could approach that of 2016, when some 30% of the reef’s corals died after suffering through what were then unprecedented levels of heat stress. 

Can’t they see it’s cyclical? 

Hang on. Wasn’t that 93 per cent? No. That’s just the mainstream media scare figure used at the time to appease their owners: the same predatory billionaires that profit from the global boiling scam. It was never an accurate figure, never credible, yet the Greens repeatedly peddled it. 

In summary, the reef had a serious bleaching event in 2016, and within a few years the coral extent was back to normal. By the way: the first scientifically recorded bleaching was in 1926. Scientific records show that bleaching has been a natural part of the Great Barrier Reef cycles and other reef cycles for millennia. That is fact. This is not some esoteric discussion. These Chicken Little claims from the Greens have consequences. Scare stories about the reef dying cause tourists, including international tourists, to cancel their holidays on the Great Barrier Reef, destroying livelihoods in Great Barrier Reef communities on the Queensland east coast. People instead go to a country where the politicians are not scaring off the tourists. Jobs are lost every time the Greens use the Great Barrier Reef as a political football. There’s not even any science behind their claims. 

At times the reef can be a naturally fragile ecosystem. We know that. Certain naturally occurring events can impact it. The greatest danger for the barrier reef is flooding. Tropical cyclones dump fresh water into a river catchment system that carries rainwater hundreds of kilometres onto the Great Barrier Reef. Freshwater plumes kill saltwater coral polyps, and the event is declared a bleaching event—all natural, all cyclical, quite common. 

What did we have three months ago in Queensland? A severe flood event—entirely natural. What do we have now? Coral bleaching—entirely natural. Don’t take my word for it. Please read James Cook University’s article titled ‘Back-to-back cyclones and flood plume impacts on the Great Barrier Reef’, which confirmed freshwater coral bleaching was recorded along the reef. 

Now the climate boiling scammers are trying to blame this on natural climate variability, so let me give you the inconvenient truth about that. I want you to reference the study titled ‘Great Barrier Reef study shows how reef copes with rapid sea level-rise’ from the University of Sydney website. I’ll publish the link. To quote from the study: 

Using unprecedented analysis of 12 new drilled reef cores with data going back more than 8,000 years, the study shows that there have been three distinct phases of reef growth since the end of the Pleistocene era about 11,000 years ago. 

It goes on to say: 

‘We wanted to understand past reef resilience to multiple environmental stresses during the formation of the modern reef,’ said the lead author Kelsey Sanborn, a PhD student at the School of Geosciences at the University of Sydney. 

It continues: 

The study was an international collaboration published in Sedimentary Geology, which revealed a period around 8,000 and 7,000 years ago when the reef growth slowed as it was exposed to multiple stressors, including likely increases in sediment and nutrient flux on the reef. 

I wonder what could cause the sediment and nutrient flux that damaged the reef 8,000 years ago. Well, it can’t be coal fired power stations, it can’t be internal combustion engines or people living in freestanding homes on quarter-acre blocks, and it certainly couldn’t have been air travel. What could it be? Of course, I have it, eating meat! That’s it! If the local Aboriginal population had just stopped eating red meat and instead grew soybeans, those tropical storms would not have dumped nutrient-rich floodwaters onto the reef. 

Study co-author Associate Professor Jody Webster said: 

We need to understand the past in order to predict the future. This paper and Kelsey’s broader research examine how sea level, surface temperature, sediment in the water, nutrient influx and energy inputs into the reef system affect its vulnerability to environmental change. 

It goes on: 

The reef system survives because of a delicate balance these environmental factors. 

All natural.  

Whenever the balance of the reef is disturbed, a bleaching event occurs. It’s entirely natural. It’s in a symbiotic relationship with other organisms. There’s no doubt that when an unusually hot day corresponds to an unusually low tide, the reef will bleach, and it will bleach from a cyclone event and many other disturbances. That reminds me, I went scuba diving with some media off Keppel Island. We said, ‘See the corals recovering from a cyclone.’ The journalist said, ‘But you haven’t seen the real bleaching a thousand kilometres north.’ There was a thousand kilometres of reef between where we were, with the healthy reef, and their claimed bleaching event. They just ignore the healthy reef. 

For the Greens to use mother nature to promote their climate change scam is wrong—it’s utterly wrong. For reef researchers to pretend reef damage is due to climate boiling and then ask for more money to research climate change is wrong. It’s dishonest and it’s scientific fraud. The truth is that the ocean is warmed primarily from the sun, with a secondary contribution from geothermal activity—fact. The atmosphere—the thing being blamed for heating up and bleaching the reef—only warms the top millimetre or so of the ocean surface. That’s not enough to cause any harm and, by the way, we can see that in the seasonal impact. 

The climate boiling scammers can blame their sky god of warming all they like. They can demand large homes, big cars, aeroplanes, cattle, sheep, clothing, cheap power and so much more be sacrificed on the altar of their climate boiling beliefs. Saying a lie does not make the claimed science real. Repeating a lie doesn’t make the claimed science real. Our weather patterns are normal—entirely natural—and so are the patterns on the reef.  

If the Greens want to be useful, they should campaign against wind turbines—the installation of which requires whole tops of mountains being blown off mountains across northern Queensland right now, disturbing sediment and arsenic that flow through underground aquifers and winds up on the Great Barrier Reef, making these natural flood events even worse. One Nation care about the natural environment because we value the natural environment. That’s just one of the many reasons why we oppose wind turbines in pristine bushland and, for that matter, near human beings. We oppose industrial solar on farmland and on bushland. We oppose national parks being carved up for power lines, especially the Snowy 2.0 abomination. And we oppose land clearing of old-growth forests for any purpose, including grazing. One Nation is now the party of true environmentalism. And the Greens? Well, they’re the party of promoting the political agendas and the pockets of parasitic billionaires over the best interests of the natural environment. The Greens peddle the United Nations World Economic Forum’s antihuman agenda, which is in turn based on a lie—a false assumption. That lie, that false assumption, is that human civilisation and the environment are mutually exclusive. That is the opposite of reality. 

The reality is that, for human civilisation to have a future, we must have a healthy natural environment. History over the last 170 years shows that the health of the environment depends on human civilisation because industrial civilisation minimises human impact on the natural environment. What has human civilisation produced that is so beneficial for the environment? High-energy, low-cost, ultrareliable hydrocarbon fuels: coal, oil and natural gas. Before these hydrocarbon fuels, humans needed whale oil for lighting, killing whales. Before these hydrocarbon fuels, heating and cooking needed timber from chopped down trees. The area of land in the developed continents covered by forest over the last 100 years has increased by 30 per cent because we’re no longer chopping down trees to cook and to heat. The best friend of whales and the best friend of forests is hydrocarbon fuels: coal, oil and natural gas. 

As a servant to the fine people of Queensland and Australia, I cherish human progress. I cherish human flourishing. I cherish hydrocarbon fuels: coal, oil and natural gas. I admire human progress and human initiative. I appreciate human progress.

Senator Roberts.

Thank you, Madam Acting Deputy President. I thank Senator Polly for this opportunity to discuss job creation. In Australia, we accept that the government should provide the infrastructure and then get out of the way and let the employers create jobs. The less red tape, green tape and blue tape, nobbling free enterprise, the more real breadwinner jobs will be created. The labor Party, has brought us Queensland’s notorious reef regulations, which are in the progress, or the process of strangling the life out of agriculture across thousands of kilometres of Queensland coastline. The loss of jobs in agriculture and agricultural communities along our coastline is a disaster, that Labor’s green tape has caused. Australia’s Water Act though was the product of an unholy alliance between the Nationals, liberals and labor. It has driven family farmers off their land and decimated rural communities. Green tape is killing agriculture and killing jobs. United Nations blue tape, is having the same effect on industry. This insane idea that power generation should not produce carbon dioxide, a harmless trace gas that does not cause climate change, has destroyed heavy industry and manufacturing in Australia. China is now producing what Australia would not. labor, the Greens and the Liberal-National parties, have all championed this transfer of jobs from Australia to China. China and India are now building, 500 new coal-fired power stations to keep up with the demand for Chinese and Indian steel and manufactured goods. Renewable energy or as I call them, unreliable energy, does not create jobs. For every one new job, in so called renewables, 2.2 jobs are lost in the productive economy. Yet labor, the Greens, the Liberals and Nationals are out there everyday touting a renewable led economic boom. The only boom here is in the cost of taxpayers. Every new wind turbine costs Australian taxpayers, $536,000 in subsidies every year. That’s $13 billion dollars a year in subsidies, and that costs every household $1300 a year. Blue tape, is not about environmentalism, it’s about wealth redistribution. Large foreign companies win and small Australian businesses lose. One nation will withdraw from international agreements that harm Australia’s interests, and we will bring these jobs home. Senator Polly blames the Morrison government for poor job creation, I blame the labor, Nationals, Liberals and the Greens.

Senator Roberts your time has expired, we will now—

Senator Roberts calls on the government to lift the onerous restrictions on the fishing industry and increase fishing quotas within our waters as part of an economic stimulus package.

“Successive governments have destroyed our once profitable fishing industry with self-imposed fishing limits well below international sustainability levels and introduced vast net-free zones,” stated Senator Roberts.

The World Resource Institute’s research shows that a well-managed sustainable harvest from a coral reef is 15,000kg per square kilometre annually. The Great Barrier Reef harvest is set at an outrageously low 9kg per square kilometre, which is 0.06% of the recommended sustainable harvest.

Our fishing industry hamstrung with bureaucratic and unscientific green tape, means Australians have to import approximately 80% of our seafood.

“It is unbelievable that Australia, which has the world’s largest continental shelf fishing zone, imports so much of our seafood from Thailand and China.”
The COVID19 crisis highlighted the unnecessary green tape that hobbles so many Australian industries. Rebuilding our fishing industry requires scientific-based quotas, revisiting current and future restrictions and reducing the net-free zones.

“Australia should have one of the world’s most profitable fishing industries and supply Australians with the majority of their seafood. Instead they are drowning in green tape and the industry is facing ruin.”

He added, “The Lib-Lab duopoly through unfair trade agreements and needlessly signing United Nations’ agreements has decimated our fishing industry.”

“The COVID19 crisis has sent us a stark reminder that unfettered globalisation has left Australia vulnerable and our sovereignty diluted”.
