It’s been one year since dead fish began washing up on South Australian beaches, as the largest algal bloom in Australia’s history spread along the coast.

Marine ecologist Dr Scott Bennett was part of the team that first surveyed the bloom – coming face to face with the algae’s devastating impact.

Twelve months on, the bloom is still there, the damage has spread, and many of the warnings scientists made in those early days have proved well founded – particularly the damage to marine life.

Today, we’re bringing you an episode from 2025 with marine ecologist Dr Scott Bennett, on what caused the bloom, what he saw beneath the surface, and what it means for the fate of the ocean.

This episode first aired in August 2025.

South Australia does not usually wake up on election day at the centre of the national mood. But this morning, a contest that looks settled on paper is carrying a much stranger energy.

Peter Malinauskas is expected to win comfortably. The real movement is happening elsewhere; in the noise around One Nation, the protest vote in the middle of a cost-of-living crisis gathering around the once marginal party, and the possibility that a state election could end up telling us something bigger about where Australian politics is heading.

Today, Editor of InDaily SA, Belinda Willis, on the state election that may be a whitewash for Labor, but a warning for everyone else.

While the world focuses on the war underway in Iran, Israel and the Gulf, there is another war front developing – Lebanon.

Lebanon’s Iranian-backed Shia group, Hezbollah dragged the country into the war, attacking Israel after a joint US-Israeli airstrike killed Iran’s Supreme Leader, Ayatollah Ali Khamenei.

Israel then hit back, bombing Beirut and amassing tens of thousands of troops on the border.

Meanwhile, more than a million Lebanese people are now displaced, forced to flee their homes as the attacks continue and Israel demands evacuations.

Today, Michael Young, editor of Carnegie’s Middle East Center blog on whether Lebanon could see a ground invasion and what Israel’s plan is to reshape the region.
