Brad Hodge (35*) and Andrew Symonds (33) saved Australia from deep blushes.
Ricky Ponting surprisingly chose to bat on a gloomy evening and soon paid the price. In the very first over itself, bowled by Elton Chigumbura, Matthew Hayden fell caught behind by wicket-keeper Brandon Taylor.
Hayden played an arrogant pull shot to the fence but there was surprise in store for those who thought the usual Australian dominance would kick start from there. The left-hander touched a wide delivery outside the off-stump and walked back to the pavilion.
Adam Gilchrist was the next to go - in the third over - when he tried to pull Chigumbura out of the ground but Stuart Matsikenyeri took a good catch. Gilchrist made four off six balls.
Ponting played a bad shot off Gary Brent but Chigumbura pulled off a wonderful catch to send back the Australian skipper for eight, made off 15 balls.
The Zimbabwean dominance could be gauged from the fact that they managed to 48 for four when Visumusi Sibanda brilliantly ran Michael Hussey out. The Aussies limped to their 50 off 63 balls.
Andrew Symonds tried to pull things together but once again, the Zimbabwean brilliance in the field cut short an Australian innings. Symonds was going well, having scored 33 runs off 25 balls with four fours but he was stumped by Taylor's quick glove work off Masakadza.
The Zimbabwean bowlers bowled to their strengths - which were keeping it in the right areas and taking pace off the ball - but it was their fielding which caught the eye. They were simply outstanding. The Zimbabwean diving and catching were spot on, and in the entire 20 overs, there was just one instance of a mis-field that allowed an extra run.
Brent took two wickets for just 19 runs in his four overs while Chigumbura took three for 19 runs in his three overs. None of the Australian batsmen could stay with Hodge and instead fell back to baseball style hitting. Needless to say, they paid a heavy price.
Australia 138 for 9 in 20 overs (Brad Hodge 35, Andrew Symonds 33; Chigumbura 3 for 20, Brent 2 for 19) Vs Zimbabwe.
