Scotland's miserable run against Australia continued with a comfortable win for the visitors at Murrayfield.
Simon Webster gave the Scots some early hope with a try but Australia soon took complete control of the game.
Stephen Larkham touched down and Mark Gerrard added two more tries after the interval, while Stirling Mortlock was in fine kicking form.
Hugo Southwell grabbed a fortunate try for Scotland but Stephen Moore and Chris Latham replied with late scores.
Frank Hadden's side were aiming to end the year unbeaten on home soil but they were second best for long spells as Australia notched up their 16th consecutive win against the Scots.
Scotland started brightly and went ahead thanks to Chris Paterson's third minute penalty.
The lead was extended soon after when Australia failed to deal with a huge up-and-under from Dan Parks and the ball was worked out wide to Webster, who cut inside to deceive three opponents and scamper over for his seventh international try.
MY SPORT: DEBATE
Paterson converted but Scotland's wretched run of injuries continued when Webster had to leave the field with what looked like an ankle problem.
Southwell came on to play at full-back, with Paterson moving to the wing.
Stirling Mortlock kicked the first points for Australia when Gavin Kerr was penalised for a high tackle.
And the scores were level on 18 minutes when Mortlock converted after Larkham bundled in for a try after a sustained period of pressure.
The Aussie onslaught continued and Mortlock added two simple penalties as mistakes crept into the Scottish game.
Australia continued to dominate after the break and Gerrard flew in at the corner after a powerful surge from the impressive Larkham.
Mortlock converted from a tight angle and his flawless kicking continued after Gerrard claimed his second try after some poor tackling from the Scots.
A slip from Lote Tuqiri gifted Lamont the chance to gather a long kick from Parks to give Scotland a glimmer of hope but Paterson was wide with the conversion attempt.
Scotland were given a further boost when Alister Campbell was sin-binned for persistent foul play.
The home side were camped inches from the try-line but the Aussies held firm and, when the ball was moved wide, the attack broke down with a terrible fumble from Marcus Di Rollo.
And more slack play allowed the 14-man Aussies to stretch their lead late in the game.
Phil Godman and Southwell both missed tackles on the rampaging Phil Waugh, who slipped but handed off to Matt Giteau, with Moore then touching down.
More flimsy tackling allowed Latham to breeze through, while Mortlock was again on target to complete a one-sided victory.
