Australia's affordable housing crisis is often portrayed as a competition between younger renters and older homeowners. But a new analysis of Australian Institute of Health and Welfare data suggests that women over 50 are an increasingly vulnerable group. Since 2012, there's been an 83 per cent increase in older women relying on friends or family for accommodation.

Unions and civil liberties groups have described the Federal Government's new social media policy for public servants as reprehensible and absurd, saying it could even be in breach of the Constitution. The new policy prohibits the liking or sharing of anti-Government material on any social media platform and could see workers demoted - or even sacked - over any breaches.

At a series of community meetings local residents are complaining about street based sex work in their community. It comes as a bill to decriminalise sex work in SA progresses through parliament. Sex workers themselves have begun coming to the meetings, protesting their right to work safely and without stigma.

There are calls for more training for teachers to help them deal with problematic sexual behaviour in primary schools. In a recent study teachers reported students threatening to rape other students, simulating intercourse and coercing others to engage in sexual behaviour. The research has raised concerns about teachers ability to differentiate between victims of abuse and children who are mimicking what they see in the media.

The four-time Olympic gold medallist, Betty Cuthbert, has died at the age of 79. The sprinter burst to fame as an 18-year-old at the 1956 Melbourne Olympics, and is still regarded as one of Australia's greatest athletes. For the second half her life, she endured the cruelties of the crippling disease, multiple sclerosis.

Police have revealed extraordinary details about a Sydney-based terror plot, with two men accused of attempting to place an explosive device on a commercial plane. And in a second plot, it is alleged the men were building a device capable of dispersing toxic gas in a crowded place.

Etihad Airlines, the alleged target of the failed Sydney-based plot to smuggle a high-grade explosive device onto a long-haul aircraft, is regarded as one of the world's best at managing aviation security. Retired Australian pilot James Nixon, who captained A-380 planes from a Dubai-based carrier, gives Peter Lloyd a cockpit-eye view on the alleged plot. He has joined other pilots in calling for stricter security at Australian airports.

A sensational leak of a transcript of a phone call between President Trump and Prime Minister Malcolm Turnbull's been met with disappointment by the Government. Former prime minister Kevin Rudd says the phone call shows Mr Turnbull was 'deceptive' about a deal to relocate refugees on Manus Island and Nauru to the US. But ministers are defending Mr Turnbull, saying he stood up for Australia to save the deal which Mr Trump wanted to axe.

The World Today's Nick Grimm speaks with Pulitzer-prize winning investigative reporter David Cay Johnston, the author of an unauthorised biography of Donald Trump. He calls the transcript of the conversation between the US President and Prime Minister Malcolm Turnbull 'astonishing' and says the President clearly didn't understand the terms of the asylum seeker deal made by the Obama administration. Johnston also discusses the grand jury reportedly empanelled by special counsel Robert Mueller into Russian interference in the 2016 US election. He expects the counsel to investigate alleged money laundering facilitated by Mr Trump over decades.

Asylum seekers in the Manus Island detention centre are confronting guards and police who are trying to lock gates and clear one of the accommodation compounds. The stand-off comes after three days of protests inside the centre against attempts to force refugees to move out. Detainees say a large group of local police and centre guards are being directed by Australian Federal Police and Border Force officers as to how to close the compounds progressively and move the men to a transit centre near the main town of Lorengau. The detainees insist that the transit centre is unsafe.
