According to Environment Institute members Dr Dominic McAfee and Prof Sean Connell, the bloom is far too widespread for large-scale chemical, physical, or microbial trials. Instead, prevention and resilience are key. Oysters in affected areas are feeding on algae, mussels are cleared of toxins, and SA has committed to restoring 15 hectares of shellfish reefs. As climate change fuels more marine heatwaves and floods, HABs will return. Investing in oyster reef restoration and nature-based solutions could future-proof our coasts.

Professor Justin Brookes highlighted that while algae play a crucial role in marine ecosystems, the current Karenia mikimotoi bloom is toxic and spreading rapidly due to warm temperatures and nutrient-rich waters. Future Making Fellow Dr Dominic McAfee described the event as an “underwater bushfire,” urging a coordinated response similar to land-based natural disasters. Both experts emphasised the need for continued monitoring and proactive measures to protect marine life and coastal communities.
