SAINT Columba Anglican School students Hayden and Tayler Miall have long battled each other on the sporting field.
The twins took their abilities into the pool during the school's swimming carnival on February 22.
Heading into the final race of the day only one point separated them in their pursuit of age champion glory.
Previously the boys had achieved two age championship wins each during their primary school years.
School sports administrator Jason Johnson said there wasn't much that separated the boys in their races.
"There were a few photo finishes on the day," he said.
It came down to the last race in the 100-metre freestyle and Tayler was one point ahead of Hayden.
Hayden needed to win the event which he did win.
It resulted in both boys being crowned dual age champions for 2019 in their final year as primary school students.
"It's the first time they've shared the age championship title," Johnson said.
"It might have happened before with dual winners, but not twins."
The boys also headed off to the Hunter Regional Independent School Championships on March 7 in Newcastle.
Last year Tayler won his breaststroke event and went onto CIS Champs at Sydney Olympic Park.
