Investigations into the mysterious death of Melbourne man and suspected Israeli spy Ben Zygier will end the speculation and give his family some peace, Australia's Jewish community says.
Zygier was a dual Australian-Israeli citizen who died in a maximum-security Israeli prison in December 2010 aged 34.
It's believed he worked for Israel's spy agency Mossad but it remains unclear why he was arrested and imprisoned.
The Executive Council of Australian Jewry discussed the case for the first time on Tuesday.
"We look forward to the official inquiries publishing concrete information about the circumstances surrounding the death of Ben Zygier in the hope that it will put further rumour and speculation to rest and bring some comfort to his still-grieving family and friends," council president Danny Lamm said in a statement.
Reports have suggested Zygier was arrested for sharing information about Mossad missions with Australian spy agency ASIO.
Shadow attorney-general George Brandis said he expected to receive a briefing from ASIO on the matter by the end of this week.
The Department of Foreign Affairs and Trade is investigating its handling of the case.
The Israeli parliament's Foreign Affairs and Defence subcommittee for Intelligence and the Israeli state attorney's office have both announced their reviews.
