MELBOURNE (Standard&Poor's) Sept. 6, 2010--Standard&Poor's Ratings Services said today that it has affirmed its 'AAA/A-1+' foreign and local currency sovereign credit ratings on the Commonwealth of Australia. The outlook is stable.

"But these strengths are moderated by Australia's high external imbalances, dependence on commodity exports, and the risk of a housing market correction." Public sector finances underpin the ratings.
