Alastair Cook celebrated his first Ashes century in almost seven years.
Cook made the century as he leads England's resurgence on day two of the Boxing Day Test in Melbourne.
The 33-year-old, in his 151st Test, reached his hundred in the final over of the day to take the tourists to 192-2, a deficit of 135 runs.
That came after Stuart Broad claimed 4-51 as the home side were bowled out for 327.
