SYDNEY — Australia's relationship with Japan will be "significantly invigorated" under the new administration led by Yukio Hatoyama, with experts saying similarities between him and Prime Minister Kevin Rudd will help boost bilateral ties.

Peter Drysdale, an emeritus professor and East Asian expert at Australian National University, says the future bodes well for the two countries as Hatoyama and Rudd share a conservative social democratic view of the world.

"There's a good chance that there will be a significant invigoration of (Australia's) relationship with Japan and the working relationships," Drysdale said.
