An 'Underwater Bushfire' Sparks Urgent Calls Urgent Calls for Action in South Australia

The Environment Institute is committed to supporting and doing our part to limit the impact of and promote the recovery of our marine systems that have been devastated by an algal bloom.
We are fortunate to house leading expert researchers that have been on the front foot to inform the media and government about the drivers and impacts of the recent agal bloom scourge affecting our coastal waters.
Today, the SA government met to discuss the potential for more funding on top of the federal government pledged $14 million to help manage this crisis. This support is welcome. The funding will go towards a range of activities, including monitoring and research, beach cleaning, assisting impacted businesses and boosting community awareness. Federal Environment Minister Mr Murray Watt says 鈥渋t's intended to deal with a number of short-term requirements and some of the longer-term needs that South Australia is going to face as it recovers from this event."
However some remain upset that was this event was not declared a national disaster. Senator Sarah Hanson-Young pointed out "If this was a massive bushfire on the east coast or a big climate bomb of weather, huge flooding, cyclones, it would have been declared a disaster."
National Disaster Definition and Legal Implications
By labelling the algal bloom event a 鈥渘ational disaster鈥, in turn it鈥檚 parallel to declaring a 鈥渘ational emergency鈥, Federal laws enacted in 2020 would have permitted the governor-general to declare a national emergency if the prime minister deemed the event to be causing (or likely to cause) harm that is 鈥榥ationally significant鈥. Nationally significant harm means harm that has a significant national impact because of its scale or consequences, observed听
If declared a disaster, "it听can听trigger听access听to听a听particular听pot听of听money,听the听kind听of听disaster听relief听funding,"听she tells Channel 10 News Lunchtime.听Whilst the legislation takes a broad view of what qualifies as nationally significant harm, including criteria such as "harm to the life or health of animals or plants" and "harm to the environment", the Act is limited to nationally-significant contexts she says.
The problem with disaster arrangements is the definition " doesn't cover marine heatwaves [and] algal blooms. It doesn't actually even cover long-running heatwaves on land," Dr McCormack adds.听 The announcement of the funding is great starting point expresses Dr McCormack, as it will help communities and businesses impacted by the event, as many haven't had fish for months, and the funding is "a welcome investment and protection for them."
Environment Institute Members Perspectives on the Crisis
Future Making Fellow Dr Dominic McAfee compared this environmental event to 鈥渁n underwater bushfire鈥 and would like to see 鈥渁 response that's akin to how we respond to bushfires on land鈥.听This stresses how serious this disaster really is, which has been reflected in several media outlets including听and The Guardian.
Professor Justin Brookes, Environment Institute member, notes that the rate of growth of the bloom is competitive 鈥淭here [are] lots of different species of algae, and some can dominate systems. We tend to see a succession - some will rise up and then others will take over,鈥 he said听speaking with
he algal bloom has been causing havoc in South Australia since early March, affecting important water sources like the Coorong Lagoon, a vulnerable area at the bottom of the River Murray, and making its way into the Port River.
Dr Christopher Keneally, Environment Institute member, spoke to about the spread of the bloom. 鈥淭he harmful algae bloom has blanketed large areas of South Australia鈥檚 coastline and has already killed many fish, sharks, and a wide diversity of other marine life, with devastating environmental and economic effects.鈥
Dr Nina Wootton, Environment Institute member, also spoke with describing the outbreak as an ecological crisis. "While not yet formally declared a national disaster, the scale of this event, spanning hundreds of kilometers of coastline and devastating huge numbers of marine life, is unprecedented for the region and demands national attention," she said.
鈥淚f this was happening in more populous areas, action would have already been taken to call this a national disaster. Without serious changes, we can expect more of these ecological shocks in the future."
The Path Ahead
As to why the bloom has spread so fast, Professor Brookes along with other experts say 鈥淲e're not really sure why this particular algae has chosen this moment to come along. It's sort of colonised right across the coastline. But it is a problem species because it's toxic, and it's probably not a great food source either.鈥
Multiple experts from the Environment Institute have noted that the bloom thrives in warmer temperatures, Dr Wootton says 鈥淚n this case, unusually warm waters and calm conditions appear to have created the perfect storm. This is climate change in real time. The consequences of years of inaction are now unfolding before our eyes.鈥
Speaking with the said 鈥淚t seems like almost everything has died.鈥 Further expressing just how confronting the affects are as 鈥淚t hits quite hard when you鈥檙e on the beach, and you can also see and smell the foam鈥 when speaking with ABC National Radio. 鈥淭he impacts we鈥檙e seeing now could just be the start of something more prolonged.鈥 Dr McAfee adds.
Dr McCormack was interviewed by , saying apart from financial assistance, we are limited as to what can physically stop the bloom from spreading. 鈥淚n this case what we're really talking about is national recognition of an absolute catastrophe unfolding in south Australian waters,鈥 says Dr McCormack.
Further commenting for, Dr McCormack adds 鈥渢he disaster relief funding arrangements do not specifically provide for algal blooms or slow-onset disasters such as marine heatwaves (or land-based heatwaves, for that matter).鈥 听Why is this an issue? Dr McCormack explains that extreme events can be quickly, like fires, or slowly, such as droughts and heatwaves, however 鈥渂oth kinds can cause serious harm鈥 she says, emphasising that 鈥渢hese funding arrangements will need to be more flexible as the climate changes.鈥
