"Scientists are warning the wildlife impacts of a marine heatwave that has
driven a catastrophic algal bloom off South Australia are likely to be
equivalent to those from the black summer bushfires, and demand a similar
response from governments.

Experts from five Australian universities say “one of the worst marine
disasters in living memory” requires rapid investigation by federal and state
governments to identify any at-risk species and fund emergency interventions if
necessary.

In a report by the Biodiversity Council, an independent expert group founded by
11 universities, the scientists called on governments to commit to seven
actions to respond to the “foreseeable and even predicted” event and to prepare
for “an increasingly dangerous and unstable future”.

As expected, the federal Senate on Wednesday night established an inquiry into
the disaster that has killed thousands of marine animals off SA. The Coalition
senator Anne Ruston earlier accused the federal and SA governments of being too
slow to act on the “significant environmental issue”, “allowing it to massively
escalate into a serious ecological disaster”.

While she welcomed this week’s assistance packages – with federal and state
governments each announcing $14m – she said it seemed “manifestly inadequate to
deal with the impact on the affected communities”.

“It fails to recognise the magnitude of the response needed to both address the
problem and deal with the clean-up,” the senator for SA said."
