Good morning, I'm Lincoln Archer from the ABC News website. Conditions have eased slightly in north Queensland, but the flood emergency remains.

We're also looking at claims of overcharging in Medicare referrals, possible movement on gambling ads as parliament resumes (which you can follow live, of course), and trials begin involving soccer stars Jenni Hermoso and Sam Kerr.

What’s the story: Some areas of north Queensland have received nearly 2 metres of rain in three days. And while the rain is expected to be "easing off", flood levels remain high and the danger remains real, with emergency warnings still in place, homes still at risk and residents told to avoid contaminated water. Follow the latest this morning in our live blog.

'We're not through this yet': That's Queensland Premier David Crisafulli, who is warning of a massive rebuild after highways were cut and bridges torn apart. Here's the full interview from last night's 7.30 ▶️. 

Elsewhere, some relief: Meanwhile the heatwave which has been punishing Victoria is set to give way to a cooler change over the course of the day, according to the weather bureau. Firefighters still battling blazes in the state's west are now bracing for a wind change.

EXTRA: The team in Victoria has taken a look at dry lightning, the weather phenomenon being blamed for igniting most of the current fires.  

• Medicare referrals: If you’ve been lucky with your health, you might not know that GP referrals to specialists can expire. Sometimes that can lead to what one expert has called “significant overcharging”, leaving patients “betrayed”.
• Marginal interest: Yesterday we looked at Four Corners’ deep dive into Labor’s heartland woes. Today the team is crunching the numbers on (formerly) unlosable Coalition seats, and the insurgent threat which has Peter Dutton fighting on two fronts.
• US immigration: Today’s ABC News Daily episode hears from a lawyer in Houston, discussing the Trump administration’s crackdown. She tells of parents scared of raids, detention and deportation asking if it’s still safe to send their children to school
