Good morning, Thomas Morgan and Annabel Bowles here with today's AM newsletter.

It's Wednesday, August 26. Country music legend Dolly Parton has died aged 80, after decades of stardom. In other top stories today, internal government documents reveal a tech giant's massive AI plans for NSW, and we look at how the Tampa affair changed politics 25 years on.

Dolly Parton: The world is reflecting on the legacy of superstar Dolly Parton, after her family announced her death this morning.

A beloved icon and philanthropist, Parton was one of the most recognisable stars of the country music world for decades.

Parton was best known for classic songs like Jolene, I Will Always Love You, and 9 to 5, and won 11 Grammy Awards from more than 50 nominations.

She amassed a legion of fans as one of the most decorated performers of all time. Parton's proudest achievement, she once said, would always be her songwriting.

Data centre plans: Our national AI reporter Cam Wilson today reveals Anthropic, the US tech giant behind Claude, met with the NSW government to discuss a massive data centre build-out.

Net overseas migration: Or NOM for short. Politicians have been fixated on it of late, but what is it and why does it matter? The measure is causing internal headaches for One Nation as it tries to land its position on migration.

Secret Harbour: Speaking of One Nation, the party faces its first test in WA with a looming by-election. 7.30's Courtney Bembridge is in the electorate as voters' loyalty to Labor and the Liberals drifts.

Market drama: Global debt markets are groaning under the weight of government spending and stubbornly high inflation. As David Taylor writes, decisions being made a world away could have profound consequences here.

Delivery dilemma: A crime network crackdown is causing delays in shipments from China to Australia. With the logistics logjam causing months-long delays, some customers are going postal.

Former prime minister John Howard doesn't have regrets about how he handled the Tampa Affair, even 25 years on.

Few events defined the politics of early 2000s Australia quite like the boat arrivals debate, and the Howard government's hardline stance earnt it international condemnation. Today, many of those once-critical nations are following suit.

Few things are as synonymous with the Australian summer as surf lifesavers, and now it's hoped the upcoming 2032 Olympic Games could present an opportunity to showcase their importance to the world.

With competitors gearing up for this summer's Iron Series, the event's top two athletes are sharing their personal stories in the hope that making surf lifesaving an Olympic sport could help save lives.

That's it for today, thanks for reading.
