It was Scotland's first win against the Wallabies since 2012 and ends a run of three straight defeats by Australia, including the 2015 World Cup quarter-final loss that was decided by a last-minute Bernard Foley penalty contentiously awarded by referee Craig Joubert.
Centre Duncan Taylor had given Scotland the lead with a try in the 15th minute, converted by Russell, as the home side were sluggish out of the blocks.
Full-back Israel Folau levelled just four minutes later but Scotland's all-action fly-half restored the lead with a try of his own.
Folau doubled his tally with Scotland down to 14 but the visitors still led 17-12 at the break.
Will Genia and Hamish Watson traded scores either side of the hour mark but it was the Scottish one that would prove decisive as John Barclay's team gave Gregor Townsend a perfect welcome to his new job as coach in just his second game.
