As the state advances towards the next term of government, South Australia remains in the grips of its harmful algal bloom – an issue that’s plagued SA’s marine environment and coastal communities for the last 12 months.
The bloom has spread 20 000 km since its emergence in March 2025, seeing the far-reach of environmental, personal, health and economic impact.
