Jim Chalmers says the opposition’s policy to index tax brackets would cost the budget a quarter of a trillion dollars over 10 years, while claiming that the government is returning bracket creep to taxpayers.

It’s a slightly tricky position, as Angus Taylor argues that Labor is “betraying” itself because the high figure is actually how much the government is keeping and spending through bracket creep ever year.

This is a government that returns bracket creep when it is responsible to do that.

That [policy] would cost tens of billions of dollars in extra debt interest, because he’s got these uncosted, unfunded, tax announcements that he [Taylor] made in his budget reply, which was all about trying to stave off One Nation.”

What Angus Taylor is proposing to do is to pump the most money into the economy when inflation is already at its highest.

“This betrays the fact that the government plans to raise income tax rates to the tune of $35bn. This says more about their plan than our plan …

If Labor’s saying that they plan to raise income taxes to the tune of $250bn in the next 10 years … [if] that is their tax hike, that’s their planned income tax increases.”

The Albanese government will drastically scale back the beleaguered inland rail project, abandoning plans to connect country NSW and Queensland by rail, as the price tag blows out to more than $45bn.

Originally envisioned to run 1,700km from Melbourne to a port near Brisbane, the mega infrastructure project will now only connect Beveridge, on the outskirts of Melbourne, to Parkes in central-west New South Wales – about half the distance – with the government reallocating $1.75bn of the funding to other national rail upgrades.

Climate and energy analysts said the report had again highlighted an “enormous gap” in the country’s reported methane emissions from coalmines and should serve as a wake-up call.

State’s police minister says buyback ‘doesn’t focus on keeping guns out of the hands of terrorists and criminals’, leaving NSW only clear supporter of plan

Queensland has rejected key recommendations from the Bondi royal commission’s interim report, insisting plans for a national gun buyback will not keep weapons “out of the hands of terrorists and criminals”.

The report, handed down by commissioner Virginia Bell on Thursday, raised doubts about whether efforts to establish a national gun register after the 2022 police killings at Wieambilla in Queensland had been “unduly leisurely”. Bell recommended the federal government and the states speed up a jointly funded weapons buyback scheme.
