The Australian government has expressed grave concerns about the escalating conflict in Sudan, with 158 citizens and their families known to be in the African nation.
The Department of Foreign Affairs said the immediate priority is their safety and consular assistance is being provided.
But that help is limited with no embassy in Sudan.
"The provision of consular services is severely limited at this time due to the volatile and dangerous situation," a department spokesperson said in a statement.
Australians who remain in the country have been told to follow travel advice, consider the risks when attempting to leave and shelter in a safe place away from windows.
"The Australian government is deeply concerned about escalating violence in Sudan," the spokesperson said.
"We call on all parties to cease hostilities and prevent further needless bloodshed."
Australia is working with partner nations to evacuate its citizens from the country in Africa's northeast, with the closest embassy in Egypt.
German air force planes have evacuated hundreds of people amid the deadly power struggle between the army and a paramilitary force.
Sweden has also evacuated its embassy staff, their families and some citizens to Djibouti while other European nations are moving to do the same.
At least 420 people have been killed.
