Brisbane: Returning skipper Michael Clarke is keeping the makeup of his Australian team under wraps as deteriorating weather threatens Saturday's World Cup match against Bangladesh in Brisbane.

Clarke, who is back after hamstring surgery, said concerns over the format of the game amid forecasts of flooding rain from Tropical Cyclone Marcia lashing the Queensland coast would prevent him from revealing his hand. The game could be drastically reduced or even washed out completely given the forecast with Bangladesh in line to at least come out with an unexpected point given the severity of the weather forecast.
