Mr SHORTEN (Maribyrnong—Leader of the Opposition) (14:26): My question is to the Prime Minister. Today ratings agency Standard & Poor's warned that Australia's AAA credit rating will be at risk unless the government stands by its commitment to a surplus in 2021. On this basis, why is the Prime Minister still persisting with his $50 billion tax handout to big business, when a ratings downgrade will push up the mortgage repayments for Australian homeowners? Mrs Sudmalis interjecting— The SPEAKER: Members on my right. The member for Gilmore.
