Matthew Hauser has won his first Noosa Triathlon, a fortnight after his world championship triumph.

After a crowded 1,500 metre swim, Hauser broke from the pack on a steamy 40 kilometre bike leg and held off American John Reed over the 10km run to win in 1 hour, 42 minutes and 38 seconds on Sunday.

Defending champion Brayden Mercer (sixth) fell on the bike leg to end his duel with training partner Hauser, while Luke Willian (third) added another Noosa podium finish.

Hauser clinched victory in the men's World Triathlon Championship Series in Wollongong last month , ending a 15-year drought for Australia across both the men's and women's categories.

"It's good to get on the top step," Hauser said.
