Day won the day in 4 hours:01 minutes 00 seconds with Surfers Paradise teammate, Kiwi Max Beattie second in 4:21.58 and Sydney’s Mitch Allum from Wanda third in 4:23.37.
“I love this event so much,” Day said.
“I had a crack at it in the under-19s and it broke me. Today I was pretty emotional, just tears of joy looking at my dad Ross and my brother and my partner and all my friends that I had there today.
“I just can’t believe it really that a kid that was 18 years old that couldn’t get on the podium – now I’ve got six.”
