Corrin was 14th in the run, ninth in the board, fifth in the swim and sixth in the ski, and qualified seventh for the iron race. She placed sixth in that to remain in the hunt.
Sunday’s grand eliminator featured three iron races – the top 10 in race one going on to race two from which the top eight advanced to the title and money-deciding race three.
Taylor was third in race one (won by Northcliffe clubmate Matt Bevilacqa) and second to Ali Day (Surfers Paradise) in race two.
It all came down to race three, but Taylor was unable to stay with the leaders and had to settle for seventh.
The race ended like a Hollywood movie. Conner Maggs looked set for a comfortable victory and even celebrated early as he skied towards shore, only for a wave to knock him from his ski. The 19-year-old’s foot got trapped between the ski pedal and strap and by the time he had got it loose, a chasing Joel Piper was almost upon him.
The pair sprinted across the sand and into the home stretch and hit the line together – Piper diving desperately, but an elated and relieved Maggs getting home.
Corrin had to come from the back of the field twice to survive the axe in races one and two of the grand eliminator. She was sixth in race one and eighth in race two.
It took its toll and she placed seventh in race three, which was won by Lucy Derbyshire.
Maggs and Derbyshire were surprise victors, each earning themselves A$25,000 ($27,500) and an Isuzu MU-X SUV.
In making it to round four, Corrin and Taylor automatically qualified for the 2025-26 series.
