The survey, done for The Australian, showed 66 percent of the electorate believe the war has not been worth the cost. That's up from 58 percent a year ago.

Only 27 percent believe the war was worth it, down from 32 percent.

Among Coalition voters, 43 percent think the war was worth it, down from 50 percent in December 2004 and 63 percent in early 2004.

Australia has 1,320 troops in Iraq. The continued violence in the country has scuttled plans to bring some of those troops home in early 2006, and President Bush might even put pressure on Howard to increase Australian forces, the newspaper said.
