Emma Snowsill made triathlon history by becoming the first woman to win three world championship titles.
The Australian claimed victory over a tough course in Lausanne, Switzerland, in a blistering time of two hours, four minutes and three seconds.
Snowsill beat over her closest rival Vanessa Fernandes from Portugal by a staggering 45 seconds.
Rounding out the podium was Snowsill's team-mate Felicity Abram who finished a further 27 seconds back.
"I'm pretty gob-smacked. I really didn't think today would be my day," said Snowsill.
"I've been feeling really out of sorts this past week and I have not been myself, so I had no expectations."
