If you’ve bought salmon at the supermarket, there’s a strong chance it came from Tasmania.

The island state is home to a billion-dollar salmon farming industry and much of it is located at Macquarie Harbour. That harbour is where Booker Prize-winning author Richard Flanagan grew up.

But it’s also home to a 60-million-year-old creature whose fate appears to be the first Australian species to be wiped off the face of the earth during this federal government.

Today, writer and contributor to The Monthly Richard Flanagan on how corporate greed, political inaction and our demand for supermarket salmon are all choking the Maugean Skate.

It’s a budget we’ll be talking about for a long time, as we head to the next election and try to escape the cost of living crisis. But even though the budget is only 36 hours old, we’re starting to see the early criticisms from rival politicians emerge.

So, has Labor spent enough to ease the cost of living? Or spent too much? And do the critics have plans of their own that would actually benefit Australians?

Today, columnist for The Saturday Paper Paul Bongiorno on where the battle lines are being drawn.

The tasering of a 95-year-old grandmother, the double-murder of a Surry Hills couple, the Bruce Lehrmann defamation trial and now the spike in domestic violence.

These are some of the biggest stories in Australia over the past 12 months, and all of them have drawn in one very powerful woman – Karen Webb, the commissioner of the NSW Police Force.

The veteran cop has found herself at press conferences and interviews having to defend herself and the force to a national audience.

Today, Middle East correspondent for The Economist Gregg Carlstrom, on Rafah and what it would take to clinch a last-ditch ceasefire deal.

It’s a small mystery in Australian politics: Why was Peter Dutton’s first major policy as opposition leader a promise to build nuclear power plants?

On the surface, it doesn’t seem like an obvious vote winner and early polling shows most Australians are yet to be convinced.

But this may be less about votes and more about holding the Coalition together, with the help of a lobby group most of us have never heard of.

Today, investigative journalist and contributor to The Monthly Marian Wilkinson on the Coalition for Conservation lobby and their links to Peter Dutton’s nuclear promises.
