SYDNEY - Run-machine Travis Head hit a swashbuckling 163 and Steve Smith a composed unbeaten 129 as Australia built a 134-run lead over England to seize control on day three of the fifth and final Ashes Test on Tuesday.
It was destructive opener Head's third ton of the series, to go with the phenomenal match-winning 123 he made in Perth and 170 at Adelaide.
The fidgety Smith was equally impressive, with his 37th Test hundred driving the hosts to 518-7 by stumps at a packed Sydney Cricket Ground in reply to England's 384 after they began the day on 166-2.
Beau Webster was alongside him on 42 at the close.
The hosts lead the series 3-1 and have already retained the Ashes, with England desperate for another win after victory at the previous Test in Melbourne.
Head brought up three figures off just 105 balls and seemed destined to score 200.
But he came undone in the third over after lunch by the part-time spin of Jacob Bethell, who was bowling for the first time in the series.
In his second over, Bethell trapped the 32-year-old lbw attempting a sweep shot to end a magnificent knock.
Smith treated Bethell with contempt, launching him for a big six on his way to a 13th Ashes century to move past England legend Jack Hobbs. Only Donald Bradman with 19 has more.
Usman Khawaja, in his 88th and last Test after announcing his retirement, fell lbw to Brydon Carse for 17, while Alex Carey made 16 before Josh Tongue enticed an edge.
Nightwatchman Michael Neser made 24 and Cameron Green 37.
Head resumed on 91 and Neser on one after Jake Weatherald (21) and Marnus Labuschagne (48) were out on Monday.
