My question is addressed to the Prime Minister, and I refer the Prime Minister to the Frontier Economics report released yesterday. Frontier’s analysis shows that, under the government’s proposed emissions trading scheme, typical household electricity prices will cost up to $240 more per year than under Frontier’s proposed arrangements. Prime Minister, why do Australian households have to pay higher electricity costs because of the government’s unwillingness to consider greener, cheaper and smarter alternatives to its flawed emissions trading scheme?
