Nathan Lyon and James Pattinson claimed three wickets each as Australia moved into a winning position on the third day of the tour match against Somerset at Taunton.
After declaring their first innings on 321 for five, a lead of just one run, with Phil Hughes unbeaten on 76, the tourists bowled out Somerset for 260, off-spinner Lyon taking 3-73 and seamer Pattinson 3-61.
James Hildreth hit a fluent 75 and Peter Trego a belligerent 60 for the hosts, but the tourists were left with a victory target of 260 on a still flat pitch. By the time bad light ended play four overs early, they had reached 36 without loss.
The day began badly for Michael Clarke and his team as they looked to build on 266 for four when Brad Haddin was pinned lbw by Jamie Overton's full first ball and departed without adding to his overnight 38.
But from then on Hughes, who had resumed on 44, and James Faulkner (22 not out) batted with few alarms, adding 55 before Clarke closed the innings after 50 minutes' play.
Hughes had reached his fifty off 88 balls, with seven fours, and the left-hander looked untroubled for most of his two hours and 43 minutes at the crease.
Somerset looked set to make a real contest of it when Marcus Trescothick (32) and Nick Compton (34) took their second-innings score to 62 without loss at lunch.
But after the interval Trescothick was caught behind off Pattinson, walking when umpire Mark Eggleston failed to spot the edge, and first-innings centurion Chris Jones fell leg before to the same bowler for a single.
It was 87 for three when Compton appeared unlucky to be judged lbw to a turning delivery from Lyon, who extracted spin and occasional bounce from the River End.
Hildreth followed up his first-innings half-century with another effortless-looking knock. After Craig Kieswetter had been bowled by Peter Siddle shouldering arms for 18, the former England Lions captain moved to fifty off 61 balls with nine fours and a six.
It was 168 for four at tea but, as on day two, Australia bowled with more menace in the final session and Somerset slumped to 204 for nine, Mitchell Starc producing two fine deliveries to account for Alex Barrow and George Dockrell.
Lyon had Hildreth brilliantly caught at midwicket by Hughes and also induced Craig Meschede to play onto his stumps.
But the spinner's figures were dented when Trego launched a typically swashbuckling counter-attack in a hugely entertaining last-wicket stand of 56 with Gemaal Hussain.
The powerful all-rounder took 18 off an over from Lyon, hitting four boundaries including a reverse-sweep, and raced to a half-century off 47 balls with eight fours. He had faced only 53 deliveries when caught off a skier to give Faulkner his only wicket.
Starc finished with 2-41 from 13 overs and could feel satisfied with match figures of 6-74. Siddle and Faulkner, who were given the new ball at the start of Somerset's innings, returned 1-55 and 1-24 respectively.
Australia opened their second innings with Ed Cowan and Usman Khawaja, who found few problems seeing out eight overs before the light closed in.
