Australia's tour of Bangladesh this October has been delayed due to security concerns.

The side was due to leave Australian shores on Monday, however, their plans have now been delayed,as Cricket Australia asses the threat in Bangladesh.

"We have received advice from DFAT (Department of Foreign Affairs) and based on that information we are working with security experts and the Bangladesh Cricket Board on a revised security plan for the tour," Cricket Australia Chief Executive Officer James Sutherland said.

"We want the tour to go ahead and are planning for that, but the safety and security of our players and support staff is our number-one piority and won't be compromised."

Australia's last tour of Bangladesh was in 2011, when the side played three one-day internationals.

DFAT says Australians who are currently in Bangladesh should exercise extreme, particularly in Dhaka, the country's capital, due to political unrest.

"Australians should be aware that normal travel in many parts of Dhaka is not possible due to arbitrary acts of violence."

At this stage, it is unknown whether Australia's warm-up games or their tour will go ahead.
