Answer 2

It seems that changes in Pacific Ocean circulation patterns have a strong effect on the weather conditions in Australia--especially the patterns called El Niño and La Niña, which have strong effects on weather around the world. See second url-which discusses effects on Australia.There is some speculation that global warming has played a part.
