Abbott pays tribute to Jewish diggers

Prime Minister Tony Abbott has paid tribute to Australia's "Jewish warrior citizens" at an Anzac commemoration service in Sydney.

More than one in 10 Australian Jews - some 2500 - volunteered for World War I a century ago, 300 of whom never returned.

"Jewish people made a more than proportionate contribution to the war effort," Mr Abbott said at the service at The Great Synagogue in Sydney's CBD on Sunday.

He paid special tribute to General Sir John Monash, whose tactical nous helped break the trench warfare stalemate on the Western Front.

"His name should be as familiar in the future as it has been in the past," Mr Abbott told the packed temple.

He also used the occasion to defend Australia's ongoing military presence in the Middle East.

"We seek no dominion, we seek no changes of borders or changes of faith," he said.

"We simply work with all men and women of goodwill to preserve and advance the universal decencies of mankind."
