England enjoyed an excellent start to day two of the fourth Ashes Test as Australia collapsed in the opening session on Wednesday.
Stuart Broad (3-51), James Anderson (2-60), Chris Woakes (2-72) and debutant Tom Curran (1-65) all struck to begin the day at the MCG.
Australia lost 65-5 at one stage as the hosts - who have already won the Ashes - were left at 326-8 at lunch.
Steve Smith (76) and Shaun Marsh (61) were unable to build on a flat pitch in Melbourne.
Curran, who missed out on his maiden Test wicket due to a no-ball on day one, removed Smith.
Resuming at 244-3, Smith and Shaun Marsh appeared comfortable and the Australia captain looked ready to push his team ahead.
Somewhat out of nowhere, Smith fell at the MCG for the first time since 2014, playing on to Curran.
Mitchell Marsh (9) followed when he chopped on to Woakes and his brother Shaun - who had looked in control - followed, trapped in front by Broad, although England needed a review.
Tim Paine (24) hit some nice drives before playing on to Anderson and Broad trapped Jackson Bird (4) in front as England fought their way back into the Test.
