Australia fast bowler Peter Siddle emerged perplexed after Sri Lanka expressed concerns over alleged ball-tampering during the first Test in Hobart.

Sri Lankan officials had alerted match referee Chris Broad to television footage, which reportedly showed the Siddle lifting the seam of the ball during the tourists' first innings.

Broad later insisted there was no evidence to suggest the condition of the ball had been changed, with the 28-year-old right-armer cleared and the unofficial complaint rejected.

"Why would I want to jeopardise that when I know we can go out there and do everything in the spirit of the game and win? With 15 cameras watching, it's ridiculous," said Siddle.

"If you took a picture every time I turned around and ran into bowl it's going to look exactly like that same picture. If you watched a video of it you'd just see me turning around holding the ball and running in."

Visiting skipper Mahela Jayawardene acknowledged there had been no formal complaint to umpires Tony Hill and Nigel Llong because the players had not witnessed the alleged transgression.

"We can ask the match officials if we saw something on television whether they saw the same thing. When that was asked, they said 'Yes we saw that, we put a note on that'," he added.

Siddle was name Player of the Match for his haul of nine for 104, which afforded the home side a 136-run triumph - and one-nil series lead in the three-match series. The second Test gets underway in Melbourne on 26 December.
