I wonder what's wrong with the Aussies this time around. Making such a big score is not a easy task against them in the Australian grounds. There was a time when McGrath and other bowlers used to destroy the batting lines of opposition. Time have changed and now Australians are losing their control over the game.
You are talking about the golden age of Australia. A team having McGrath, Shane Warne, Jason Gillespie, Brett Lee. When a team have bowlers like then then scoring is difficult.
