Mr BUTLER (Port Adelaide) (14:29): My question is to the Prime Minister. Before the 2013 election this Liberal government promised to reduce power bills by $550 a year, but since then power bills have gone up and up. Today the government is again promising to reduce power bills by $550 a year. Why would Australians trust any promise this government makes about lower power bills, promises which the member for Warringah, the former Prime Minister, described today as 'merchant banker gobbledegook'?
