I think Australia is more the USA's bitch than the UK's as it goes, I think ever since the CIA had a democratically elected Australian Prime Minister booted (Gough Whitlam) because they considered him a threat to national security (he was asking inconvenient questions about the top secret USA spy bases in Australia that were not sharing any intel, just making Australia a first strike country in any nuclear conflict) they have had AU by the short and curlies.
