Australia’s A tour to South Africa has been officially called off due to the ongoing pay dispute.

The Australian Cricketers’ Association has confirmed that players are boycotting the tour given the fact a new Memorandum of Understanding has still not been agreed with Cricket Australia.

Pay talks have stalled with regards a new deal and the ACA insists stars such as Glenn Maxwell and Usman Khawaja are unhappy at having to refuse to play.

"It is with great frustration that with no progress towards resolving the current dispute, Australia A players confirm they will not tour South Africa," the ACA said in a statement.

“By making this call, the Australia A players have sacrificed their own ambitions for the collective; an incredibly selfless act that shows their strength and overall commitment to the group.

“All players are deeply disappointed at the behaviour of CA which forces this course of action, given the players would rather be playing for their country.”

The tour was due to start next Wednesday, with two four-day matches on the schedule in Pretoria before a limited overs tri-series that was also set to feature India’s A team.
