The 3.8-kilometre race was blessed with perfect conditions as more than 300 competitors swam from Coal Point to the finish line at Belmont 16 Footers.

But it was Collins who stole the show, with the 17-year-old from Redhead surf club breaking away from his competitors early on to take the win.

Closely following Daniel was his 19-year-old sister Jessica, who finished roughly four minutes behind her younger brother to take out the women’s category, as well as finish in fifth place overall.

It was the first Across the Lake swim for both siblings, but that did not show as they swam the perfect line to take their respective wins.

For the duo from Merewether, the race provided the perfect hit-out before they head to the Australian Surf Lifesaving events next weekend, where they are both expected to perform strongly in the water.
