Amid broader worries about job losses, ABC sources have told Fairfax Media there is particular concern that about 20 positions could be lost where Radio Australia and Australia Network have a combined operation.

Australia Network's bureaus in Beijing, Delhi and Jakarta are expected to close.

This comes as the head of ABC International, Lynley Marshall, speaks to staff about the next steps for Australia Network, which had its contract cancelled in the federal budget.

There was a Sydney staff briefing on Friday and staff in Melbourne and Adelaide are due to be addressed on Monday. It is understood that there will be information about redundancies at the international broadcasting service, although details are still being worked out.

ABC management is still unpicking the details of its $220 million contract with the Department of Foreign Affairs that was cut short one year into a 10-year deal. It is also dealing with funding cuts of $35.5 million over four years in the federal budget.

Australia Network broadcasts to 46 countries in Asia, the Pacific and the Indian subcontinent.

Fairfax Media understands the ABC is looking at a pared-back version of Australia Network to meet its charter obligations to encourage an ''international awareness of Australian attitudes on world affairs''.

This would involved a focus on the Pacific region and the cutting of some language services, although the Pidgin service will stay.

On Sunday, an ABC spokesman said there would be no ''announcement tomorrow regarding a new ABC international media service. Work is still continuing on the new model and the ABC is hopeful it will be able to discuss details of the service with staff in the near future.''

The spokesman described the meetings with Ms Marshall as ''part of regular staff updates''.

During Senate estimates last month, DFAT officials said the network would go off air in September, but there is an expectation among some at the ABC that the Australia Network will stop broadcasting before then.
