Lee was cited by match referee Jeff Crowe when he began celebrating after striking English batsman Kevin Pietersen on the
pads without checking to see whether he was out.
West Indian umpire Steve Bucknor ruled in the batsman's favour and Crowe found Lee guilty of excessive appealing for not
first checking with the umpire.
Lee said he thought Bucknor had given the batsman out but Crowe disagreed.
"Brett is confused about this verdict in that he thought he saw the umpire gesture that it was out," Crowe said in a statement.
"The simple fact is that Brett did not stop and wait for the umpire's actual decision, out or not out, before starting
his celebrations, something that has been stipulated over the past three years."
Australia's players normally receive a match fee of A$12,500 (7,400 euros) for each test, meaning Lee is likely to lose
A$3,125 (1,850 euro).
