The Australian government is expected to announce within 24 hours that it will vote against a Palestinian attempt to unilaterally declare statehood.
The Palestinian Authority is set to apply to the Security Council for full membership during the United Nations session on Friday.
The move has been vocally opposed by the US and Israel, but is supported by many EU countries.
An Australian MP told a JC reporter that the decision would be to oppose the vote but that more information would be given tomorrow.
The UK has not yet confirmed its position, although it is thought that the government would accept the Palestinians gaining "observer state" status at the General Assembly but with a number of conditions.
