Australia have added another dimension to the 50 overs version of the game at the 2007 tournament which culminates at Kensington Oval after seven weeks in eight West Indian regions.

While justifiably proud of their skills levels and a work ethic of puritanical intensity, the Australians have also introduced a power element which could sway Saturday's final at the spiritual home of Caribbean cricket.

Matthew Hayden at the top of the order has hit three centuries and amassed the biggest run tally of the tournament with his brutal left-handed assaults off the front foot back over the bowler's head.

His partner Adam Gilchrist, the best batsman-wicketkeeper ever, has not yet fired but he remains as potentially destructive as his opening partner should his timing return.

Andrew Symonds at number five is a wonderful athlete who possesses strength and finesse and Shane Watson, two places further down the order, can hit the ball as cleanly and as far as any of his team mates.

Australia captain Ricky Ponting said before the tournament began that big, strong men hitting through the ball were changing the nature of the game.

His observation was put into practice before Australia's final first-round round match against South Africa in St Kitts when they devoted a training session with both an open and closed net to throwing the bat at the ball.

Several screamed through the air into a sugar cane field, others threatened the safety of the spectators sitting in a small stand. The result was an Australian Cup record of 377 and an 83-run win over the then world number one side.

VARIED ATTACK

This is not to say the Australian batting is all about hitting sixes. Ponting is in the form of his life and it is difficult to conceive that anybody at any time has batted better than the quick-footed Australian skipper. Michael Clarke, his prospective heir, has also batted beautifully with precise footwork complemented by wristy drives.

Michael Hussey, the most prolific Australian batsman over the past year, has not even been required to make a contribution.

If Sri Lanka are to beat Australia they must dismiss or contain the most daunting batting line-up around and the 1996 champions have by common consent the most varied attack in the competition.

Lasith Malinga, who took four wickets in four balls against South Africa, was lethal in the semi-final against New Zealand with his round-arm slingers honing in on the batsmen at speeds consistently in excess of 145 kilometres an hour.

Chaminda Vaas continues to delight the purists by getting out class batsmen with immaculate swing bowling at a modest pace. Muttiah Muralitharan is the best spin bowler in the world who can simultaneously restrict and attack with his rubber-wristed off-spinners and the doosra which snakes in the opposite direction.

The batting on the slow Caribbean pitches where the bounce gets lower as the day progresses depends heavily on Sanath Jayasuriya, who does not need the ball coming on to him fast to score quickly but otherwise the Sri Lankans lack the power of the Australians to hit the ball over the top.

As Ponting is quick to acknowledge, no team is impregnable and one day the unbeaten Australian run at World Cups which stretches back to the 1999 tournament will end. Australia are doing everything in their power to ensure Saturday is not that day.
