A former top-level spy says the Rudd government's ousting of a Mossad agent from the Israeli Embassy in Canberra won't do anything to harm Australia's close intelligence relationship with Israel.

Warren Reed, a senior security analyst who was trained by MI6 and served for 10 years as a spook with the Australian Secret Intelligence Service in the Middle East and Asia, told Crikey that yesterday's decision to send an Israeli attache packing was a "surface politics response" that would have almost certainly been brokered behind the scenes by senior officials.

"Nothing will change," he said. "The Israeli government will jump up and down but this was almost certainly pre-arranged. While this was a valid, and material, step there will be almost no impact at all on the relationship between Australia and Israel."
