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

We start today with a look at the growing calls for a revamp of Australia's child support laws, amid concerns it is ripe for financial abuse and coercive control.

Also, a patient hits out at the use of AI in clinics after a transcription blunder, and the foreign minister will hit back at Pauline Hanson's call for a "monoculture".

And finally, from eclipses and earthquakes to bins on heads, after a week of strange headlines, we bid it adieu with the Friday news quiz.

What's the story? Survivors of physical, emotional and psychological abuse are being left to negotiate with their ex-partners for underpayment of child support, which victims and advocates say constitutes a major flaw with Australia's child support system. In some instances, ex-partners are using unpaid child support as a "bargaining tool, a threat or a way to maintain control".

'A broken system': Leah* tells the ABC her ex-partner hasn't paid a dollar of child support in nine years. That situation means every time she does a tax return, she is fined because the government assumes she has been receiving payments. But for a long time, the fear of antagonising her ex-partner meant she accepted not receiving the money.

'Getting away with it': Leah believes the system should be changed so victims and their abusers are not left to sort it out themselves, advocating instead for agency collection to be the default. That urgent call for reform is being echoed by an independent crossbencher, who says the government needs to consider updating the "decades old" child support system.

Hallucinating bot: Alarms are being rung about the use of AI to transcribe patient notes in medical practices, after a string of recent incidents. One woman says AI falsely recorded her as having taken psychedelic mushrooms, while another patient had a bot mix up which breast had been diagnosed with cancer.

Uptick in violence: Our Middle East team has ventured into a small West Bank village to talk to Palestinian families under siege from Israeli settlers. Groups of settlers have been attacking homes for months, attempting to intimidate families into abandoning their properties.

'Saudi Arabia of the Pacific': A new LNG project is being promised as an economic lifeline to one of Australia's closest neighbours, but at the moment all it is doing is fuel frustration. Major energy giants who own stakes are unhappy that Papua LNG has, for years, struggled to get off the ground. Meanwhile, locals in PNG's Gulf province say they're still waiting for more assurances from developers about the project's supposed benefits.

Toughening rhetoric: Penny Wong is set to sharpen her attacks on One Nation, after Pauline Hanson called for a return to "monoculturalism". In a major speech later today, the foreign minister will declare such an ambition a threat to national security that will "make us more vulnerable".

Analysis with Tom Crowley: While rejecting Hanson's stance, the government is still at pains to show it also wants to cut migration. But for all the posturing from Labor, the Liberals and One Nation, no party wants to explain how they will do it.

Worst-case scenario: There's been plenty of doom-and-gloom around the property market of late, but the iron laws of arithmetic suggest those fears may be overblown. Charts show how, if Australia's property values were to drop 10 per cent, many home owners who bought more than five years ago would still be ahead.

As concussion researcher Alan Pearce ran the numbers studying retired players of various contact sports, he began to realise a startling truth: the longer the career, the higher their risk of suffering a lifetime of brain injuries and chronic pain.

So with that in mind, is the informed consent of players enough? And how do the various codes, rugby league, rugby union, Aussie rules, run a sport in full knowledge that the implicit risk of brain damage is a condition of entry?

If you thought the dating scene for us humans was tough, trust Australia's wildlife to prove it can get tougher.

In fact, as we brought to you in one of our stories this week, male members of one iconic Aussie species "live fast and die young", typically at the hands of a female companion going into a cannibalistic rage.

So which species is it? Test your knowledge in this week's news quiz.

Thanks for reading, and hope you have a good weekend. We'll be back on Monday with more.
