Australia vice-captain Adam Gilchrist says the world champions are wary of the danger posed by Pakistan before this week's first Test in Perth.
Australia are overwhelming favourites to win the series opener starting on Thursday after the touring side were badly beaten in their final warm-up match against Western Australia.
Gilchrist, however, believes Pakistan are an unpredictable team who should not to be taken lightly.
"All of us have seen Pakistan be hot and cold, whether it's a tour match or an international game, so we'll be wary of them still," Gilchrist told Australian Associated Press in Perth.
Gilchrist singled out Pakistani fast bowler Shoaib Akhtar as the biggest threat.
Shoaib only averages 40 runs a wicket against the Australians but his express pace is sure to trouble the home team on the bouncy WACA pitch.
"He's done it to us before," Gilchrist said. "You give him a bowling spell where he can come on, particularly with reverse swing at his pace he can take five for 20 in one spell and totally end an innings.
"So that's an example of how dangerous they are and from what I've seen of their batting, their batting has that flair where they can take it away from you in a short space of time."
