''Umpires will decide when to start the match, but overnight and morning showers suggest that it will take time to make the wicket playable,'' an official of Bangladesh Cricket Board said.
The day's play had been scheduled to start at 0330 GMT (0900 hrs) after it had been called off yesterday following persistent rain.
Nightwatchman Jason Gillespie and skipper Ricky Ponting were not out on 28 and 19 runs respectively when the teams went off.
Australia resumed yesterday on 76-1 after they had bundled out Bangladesh for 197 on Sunday.
Australia leads the two-test series 1-0 after a three-wicket victory in Fatullah last week.
