Smoke in onboard lavvy sparks emergency plane landing

Emergency services were called to the airport on Tuesday after the captain of the Rex flight from Sydney flagged the problem: smoke in a toilet.

A spokesperson for the airline said the plane landed safely and passengers alighted normally.

"Rex Flight ZL31, operating Sydney to Melbourne, landed safely late this morning after smoke was reported in the aft lavatory. As an abundance of caution, the captain declared an emergency," the spokesperson said.

Engineers identified the cause of the smoke and the aircraft resumed operations.
