Nicholas Coci won his gun trowel speed test and a bronze medal for blocklaying at the September competition in Perth.
The Celebration Homes apprentice had 15 minutes to build a 350x350mm brick pier, which was assessed on its square, plumb, gauge, appearance and level.
The competition came down to a tie between three apprentices, but Mr Coci won based on the gauge, or height, between each of his bricks.
Landsdale resident Harley Clements was a gold-medal winner in signage at the competition and will represent Australia in the WorldSkills International Competition in Brazil next year. Wanneroo wall and floor tiler Mick Ivey also won a bronze medal at the competition.
