A relative last saw Scott Maxwell Thureson on Saturday at a house on Mildura Drive in Helensvale.

Police hold fears for his welfare because he hasn't been seen or made contact with anyone since, which is out of character.

Mr Thureson is 175cm tall, with an olive complexion, muscular build and short, dark brown hair.

He was reported missing from his Coomera home on Saturday.

Police are calling on Mr Thureson or anyone who knows where he is to call Crime Stoppers on 1800 333 000.
