Australia's players are set to boycott this summer's one-day tour of England, according to a report in The Australian.
Australian Cricketers' Association chief Paul Marsh has said that there is a possibility of industrial action over performance-related pay issues.
"There are only 29 days (the time until the first one-dayer) of negotiations left to run, so of course we are preparing for the eventuality of not having a deal in place before the end of July," Marsh said.
"We are looking at all of our different options."
The first of five ODIs is meant to begin at Lord's before further matches at The Oval, Edgbaston, Chester-le-Street and Old Trafford.
