Australia's cricketers will immediately return home from Zimbabwe if their proposed series is stripped of Test status.
Cricket Australia (CA) chief executive James Sutherland told a news conference on Wednesday there is little point in continuing with the tour if the matches lost their official backing.
"The Australian cricket team has gone to Zimbabwe to play Test and one-day cricket," Sutherland said.
"If we're not going to play that, then I'm not sure that it's appropriate for us to be there."
The status of the series, due to start on Saturday, was already under threat when Zimbabwe's leading white players went on strike, accusing the Zimbabwe board of allowing politicians to dictate the make-up of the side.
However, the crisis deepened after the Zimbabwe Cricket Union (ZCU) snubbed International Cricket Council (ICC) chief executive Malcolm Speed. He had been invited him to address the ZCU board in Harare but the invitation was withdrawn at the last minute.
The ICC responded by calling an emergency meeting on Friday to consider stripping the Australia-Zimbabwe matches of their Test status. Australia is among the 10 member nations that will vote on the issue.
Former Australian captain Greg Chappell said he supported the proposal to strip the matches of their Test status.
"I don't think anyone in cricket would be happy with that situation and we can't afford to have the standard of Test cricket denigrated from within," Chappell said.
"I think that's something that's got to be fiercely protected by the game of cricket."
