In 2011, a spy agent, who cannot be named due to classified reasons, was dismissed from the Australian Security Intelligence Organisation (ASIO) for choosing a wrong time to reveal his true identity with the love of his life.

The spy had a 4-year promising career with ASIO when he met his love, a woman from another country.

Almost like the case of "Mr and Mrs Smith," the spy later found out that the woman he fell in love with was actually a foreign diplomat living in Canberra under the supervision of her country's military attaché.

The spy made an immediate "contact report" to his agency about what he found out.

However, by then, the foreign diplomat, who also had fallen in love with him, already knew his identity as a spy.

For the ASIO higher-ups, the spy disobeyed the agency's "top secret positive vetting." He was dismissed from his work on the ground of breaching "protective security framework policy" by revealing his secret job too early on in his romance with the foreign diplomat, the Canberra Times reported.

At present, the spy, now married to the foreign diplomat, appealed to have his old spy job back and be reinstated in the agency.

However, the Administrative Appeals Tribunal upheld that the former spy had failed to appeal within the mandated 14 days of his dismissal. This made him un-qualified for appeal.

''I've tried everything; the Director-General of Security Services, the Attorney-General's Department, the Prime Minister's Department, even the Federal Police. So they [ASIO] can say what they like, it can't be reviewed, and the only thing that's left for me to do now is to sue them in a court,'' the former spy told the Canberra Times in an interview.

The ASIO, on the other hand, was outright in dismissing the case.

''An ASIO staff member can seek review from the Inspector-General of Intelligence and Security in respect of all staffing matters. A staff member may also be able to take action in the Fair Work Commission, the Australian Human Rights Commission and via judicial review. The amendments to the ASIO Act 1979 in 2011 did not affect the appeal rights of ASIO staff, " a spokesman for the agency said.
