Foreign Minister Bob Carr says he still doesn't know what Melbourne man and suspected Mossad spy Ben Zygier was doing in Israel.
Senator Carr is waiting for a report from his department about its handling of the Zygier case.
The minister says the report will likely focus on the timeline of when Australia was appraised of Zygier's whereabouts.
"What we can say about the other side of the equation, namely what he was doing with the Israelis, will be dependent on information the Israelis will give us," Senator Carr told Sky News on Wednesday.
"I don't know at this stage what that's going to be."
Mr Zygier was a dual Australian-Israeli citizen who died in the Ayalon Prison outside Tel Aviv in December 2010.
It is believed he worked for Israeli spy agency Mossad but it is still unclear why he was imprisoned.
He was the so-called Prisoner X - one of Israel's most sensitive security secrets until his identity was revealed by the ABC.
Senator Carr acknowledged that Australians had a right to know what happened to Zygier.
"We'll work as hard as we can to get that on paper and to share it with them," he said.
