With the abandonment of its net-zero policies, and leadership spills in two of Australia's largest states, the Coalition is undergoing a period of major upheaval. So what does that mean for a Westminster democracy which analysts say depends on two different political positions to succeed.

Just days after her party ditched its support of net zero emissions targets, federal Opposition Leader Sussan Ley talks to SBS Chief Political Correspondent Anna Henderson about that policy, immigration, and more in a lengthy one on one interview.

The Coalition has formally solidified its dumping of the net zero emissions target in a party room meeting in Canberra. But it's gone much further, with the Liberals and Nationals unveiling a plan to strip climate change from the national energy regulator's list of objectives, while vowing to continue to reduce emissions by monitoring the progress of other countries.

Australia's leaders remain circumspect about the terms of a security agreement with a key northern neighbour after finalising the deal with Indonesia's president. But Prime Minister Anthony Albanese says the deal commits the nations to consult regularly on matters of security, and consider possible measures should either's security be threatened.

The Liberal Party has voted to officially abandon its net zero by 2050 emissions reduction target, following a contentious internal meeting. This dramatic policy reversal, which will also seek to remove the target from the Climate Change Act, has triggered fierce internal debate among senior members and drawn criticism from the government and independents.

On November 11, 1975, Australia experienced its most dramatic constitutional crisis when Governor-General Sir John Kerr dismissed Prime Minister Gough Whitlam 50 years ago. We examine the full story of the Dismissal, from the political deadlock and the Loans Affair to Prime Minister Anthony Albanese's recent claim of a "partisan political ambush" and new evidence suggesting foreign interference.

Reddit and live-streaming platform Kick will be added to the platforms required to ban 16s when the new rules come into effect in December. Australia's impending social media ban for under-16s, which covers eight major platforms, hinges on ongoing eSafety assessments that distinguish between social media, messaging, and gaming services, explaining why platforms like Steam and Twitch were not initially included.

Australians in three states are to be offered three hours of free electricity in the middle of the day, under a scheme to share abundant solar energy harvested in non-peak hours. The plan has been welcomed by environmental groups, but some in the Opposition are unimpressed.

An unusual alliance of crossbenchers and the Coalition has forced an ongoing extension of Question Time in the Senate. They are demanding the Labor government immediately release the "jobs for mates" report, which it has withheld for two years. Critics, including Transparency International, say the government's refusal to release the report is further evidence of a "culture of secrecy" at a time when its integrity standards are under heightened scrutiny.

Under-fire Optus executives have copped a parliamentary bashing for their response to a triple-zero outage linked to the deaths of three people. The proceedings have immediately zeroed in on CEO Stephen Rue, who is being pressured to explain a significant delay in reporting the fatalities to both the government and the regulator.
