The prime minister and opposition leader faced off last night for the first debate of the election campaign.

Anthony Albanese and Peter Dutton were faced with questions from undecided voters on their cost-of-living promises, immigration policies, as well as health and education funding.

Meanwhile, two weeks after promising a plan to lower power prices, the Coalition has released its modelling for its gas reservation policy — claiming it would shave seven per cent off household gas bills while electricity bills would decrease by around three per cent.

The analysis by Frontier Economics also shows the plan could reduce industrial retail gas bills by 15 per cent.
