Finesse isn't a term generally associated with Peter Siddle, but the Australian fast bowler is striving to change perceptions. Siddle has forged a fearsome reputation for his combative approach to fast bowling, and has now turned his attention to mastering the more subtle art of swing to complement his intimidatory arsenal.

"There's always talk that I don't have as many weapons as other blokes; that I have the aggression and I charge in," Siddle said. "I love the role that I play at the moment but I'm always working on swing and other parts of my game. I'm slowly getting better at it, and it helped me in one-day cricket [in India] getting the new ball and having the chance to swing it early on. The improvement in the last two months with that will definitely help me Test cricket. There's always something to work on. I haven't got all the tools that some blokes have, but if I do my things right I have my success."

Siddle will need to be at the peak of his powers in order to achieve success on an Adelaide wicket renowned as both back- and heart-breaking for fast bowlers. He will be reunited with left-arm fast bowler Doug Bollinger for the first time since the Sydney Test in January - a match in which Australia defeat South Africa by 103 runs - after a knee injury forced out Ben Hilfenhaus.

"In that Sydney Test up against South Africa we both enjoyed the contest and we did get each other going a little bit," Siddle said. "He loves charging in there and bowling fast. He keeps everyone up beat so it's going to be good fun to be out there with him."

Siddle is not banking on Australia replicating their three-day Brisbane victory from Friday. Only one team - the West Indian side of 1951 - have lost at the Adelaide Oval before the fourth day, and the lower bounce should better suit Shivnarine Chanderpaul, who failed in both innings at the Gabba.

Making matters more difficult for Australia's fast bowlers is the recovery of Ramnaresh Sarwan from the back injury that ruled him out of the first Test. Sarwan completed a full batting session in the Adelaide Oval nets on Tuesday, and team officials are confident the veteran batsman will be available to play from Friday.

"Many factors can change what happened up there," Siddle said. "Obviously Chris Gayle, Chanderpaul and those sort of blokes didn't get a start up there but they're class players, they can make a lot of runs and they can make big scores so we've got to be on our game and work hard and attack them and keep the pressure on. Any team can turn it around, this is a new match and probably the wicket is a little bit similar to what they play on in the West Indies so it's going to be tough work."
