Australia have blown England away on day two of the first Ashes Test match in Brisbane, skittling the tourists for 136 to take a lead of 159 runs into their second innings at The Gabba.
Mitchell Johnson was the pick of the bowlers, finishing with figures of 4-61, although Nathan Lyon pitched in with 2-17 and four maidens as the hosts seized control of the contest.
Stuart Broad and Chris Tremlett came out after tea with England 94-8, and could only add 16 more runs to the total before Ryan Harris claimed his third victim.
The 34-year-old had already taken the wickets of Alastair Cook and Kevin Pietersen, before forcing Tremlett to fend off a bouncer that was picked out by Nathan Lyon at leg-gully.
Peter Siddle ended England's meek resistance by removing Stuart Broad, who picked out Chris Rogers in the deep.
Australia have 25 overs of the final session to build a sizeable advantage ahead of day three.
