Have you ever been sent in the wrong direction by GPS maps? A French national crashed into Hyde Park's Archibald Fountain earlier this week and, allegedly, he was following his maps. Plus, $300 billion, nuclear-powered submarines, and an Australian rock icon — there's been a lot going on with Australia's AUKUS alliance this week and some people reckon we're being ripped off. And, Australia has more billionaires than ever. Is this a good thing, or do we need to be taxing wealth differently?

It's the biggest deal in Australian military history, the $368 billion AUKUS alliance between Australia, the US and the UK, but this week, the government announced the deal is changing. Australia is no longer going to get a brand-new submarine — instead, we'll get three second-hand subs. So, does it matter? And does AUKUS still stack up? We speak to Peter Garrett who's leading a crowd-funded inquiry into the deal. Plus, meet mates Fletcher Crowley and Lachie Bennett.

Fletcher Crowley and Lachie Bennett have been living out a dream - two mates, visiting four countries, in three months. Their adventures have blown up on social media with hundreds of thousands of people watching them trek across the globe and pushing the boundaries of what's accessible. Fletcher has been a wheelchair user since he was 17. But he has never let that slow him down.
