At the start of the decade, Australia were very much the dominant team in both forms of the game. They had just won the World Cup for a second time and in Tests, they were well ahead of the rest. Under Steve Waugh they continued to ride roughshod over opponents and by 2001 had notched up a world record 16 consecutive Test victories.
Then they suffered their one blemish - the loss in India in 2001. But they continued to dominate both at home and abroad besides winning the Ashes with predictable regularity. Towards the middle of the decade however things didn't go so well for the well oiled Aussie machine.
Waugh retired and Ricky Ponting took over the captaincy. But while the Final Frontier of a Test series win in India was achieved in 2004 the loss of the Ashes in England the following year was a bitter pill to swallow. Australia duly regained the urn with a 5-0 clean sweep in 2006-07 but about this time there were a spate of retirements.
In quick succession Glenn McGrath, Shane Warne, Damien Martyn, Justin Langer, Matthew Hayden and Adam Gilchrist rode off into the sunset and Aussie fortunes nosedived with losses to South Africa, India and a second defeat in an Ashes series in 2009.
They slipped to fourth in the ICC Test rankings but even while their downfall was widely predicted in ODIs they displayed typical Aussie resilience to cling on the top spot besides winning the World Cup in 2003 and again four years later.
