It may be Anthony Albanese's most important policy decision. After months of internal wrangling - Labor has settled on a 2030 emissions target of 43% - this time with plans, costs and modelling. The government immediately pounced - calling it a Carbon Tax and warning of job losses and higher prices. But this time - business groups disagree. They're siding with Labor's approach. The latest climate clash came as the parliamentary year came to a troubling end for the Coalition. A backbench divided, legislation stalled,one senior Minister bowing out and another stood aside - pending an investigation into serious allegations levelled by a former staffer with whom he had an affair.

As Scott Morrison reminded his troops this week - disunity is death in politics. The warning - had little effect. Conservatives crossed the floor demanding an end to vaccine mandates. Moderates voiced concern over a failure to protect gay students and teachers at religious schools.

But perhaps most damaging of all - the government's most marginal seat-holder broke ranks - to support the urgent introduction of a federal anti-corruption watchdog.
