The first Ashes Test has been blighted by some strange umpiring decisions, here is a look at the controversies:
Ashton Agar: The 19-year-old debutant was only on six when he appeared to have been stumped. The decision was referred to the video umpire who decided to keep Agar in. He went on to make 98 - a Test world record for a number 11.
Jonathan Trott: The on-field umpire decided not to give Trott out for an lbw appeal. Replays seemed to suggest the ball hit his bat before pad but, with technology unavailable, the video umpire overruled the initial decision and Trott was out for a duck.
Stuart Broad: Australia were left incensed after Broad stood his ground despite him edging a ball to a fielder. The umpire did not spot the dismissal and Australia had used all of their reviews. The England player stayed on the field and will continue batting today.
