Transferred to Sydney, Yandra was patroling off the harbour boom gate on 31 May 1942, when a Japanese midget submarine (later identified as M-27) got entangled in the boom net. She later sighted a midget submarine (later identified as M-21) in the Harbour. Yandra and Sea Mist dropped depth charges over the site, with Yandra ramming the midget submarine on the bows.

She was returned to her owners in 1946 and returned to coastal cargo work.
