Operation Suncob was a military operation by the Australian Army in Timor in 1945 to investigate what happened to Operation Cobra. It consisted of Captain P. Wynne and Corporal J.B. Lawrence, both AIF and Z Special Unit. They were inserted into Timor on 2 July 1945 despite the Services Reconnaissance Department not hearing back from Operation Sunlag which had been undertaken shortly prior. Both men were captured and tortured by the Japanese.^[1]

It had the same aim as Operation Pigeon.
