Cricket Australia has delayed the departure of the national team's two-Test tour of Bangladesh after receiving advice from the government that Australian interests could be targeted by militant groups. 
The players were meant to leave Australia on Monday but Cricket Australia chief executive James Sutherland revealed advice from the Department of Foreign Affairs and Trade (DFAT) warned of a possible security risk in Bangladesh.
"We have received advice from DFAT and based on that information we are working with security experts and the Bangladesh Cricket Board on a revised security plan for the tour," said Sutherland.
"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 priority and won't be compromised.
"We will wait to receive updated security information early in the week before confirming the team's travel arrangements. In the meantime we are working with the ACA and keeping our players and support staff fully informed."
It's understood DFAT issued the advice on Friday, warning Cricket Australia there was reliable information that there was a threat to the safety of Australian tourists.
DFAT noted the level of alert for travellers to Bangladesh had been stepped up from the standard advice to observe "normal safety precautions". Tourists have been advised to reconsider their need to travel in the Chittagong Hill Tracts.
The region is said to be a politically unstable mountainous area that borders India and Myanmar.
Australians have also been advised by the government to exercise a high degree of caution due to the nation's uncertain political and security session. Furthermore, Australians are warned that travel in parts of Dhaka - where the squad was due to assemble - is often not possible due to acts of violence.
Bangladesh has experienced numerous acts of terrorism and security agencies in that nation continue to arrest individuals connected to terrorist organisations. There are warnings that suggest further attacks, including those against Western interests, are possible.
There were reports of political violence in the nation in   January with death and injury being caused by "violent incidents, including arson".
Australia, under the captaincy of new skipper Steve Smith, were due to play their first Test in the nation since 2006 when Jason Gillespie, who was sent in as a night watchman, scored 201.
