Yumbah Aquaculture closes Kangaroo Island abalone farm due to algal bloom impacts
Consensus Summary
Yumbah Aquaculture announced the closure of its abalone farm on Kangaroo Island by mid-2026, marking the end of the Southern Hemisphere’s longest-running abalone operation after 30 years. The decision stems from repeated harmful algal blooms, particularly a severe recurrence in late 2025, which stressed stock and made recovery financially unviable amid global market pressures. The closure will eliminate 15 permanent jobs, prompting local leaders like Mayor Michael Pengilly to call it a devastating blow to the island’s economy and industry. Both sources agree on the job losses, the algal bloom’s role, and the company’s support for affected staff, though ABC highlights redeployment opportunities and government reform calls while NEWSCOMAU emphasizes broader economic and environmental fallout. The facility may be repurposed for research, and Yumbah will continue other aquaculture ventures elsewhere in South Australia.
