Robertson's side, almost a carbon copy of the Kangaroos outfit who lifted the under 13 crown in 2017, added another piece of silverware to the Mack Oval coffers on Saturday.

It held off a storming Kolora-Noorat - who edged within one goal at three-quarter time - to notch a three-goal triumph at Reid Oval.

Robertson described the flag as "the best thing that can happen from a year of hard work".

"Most of the kids I've worked with for over four years," she said.

"I've seen them grow from tiny little babies to 11 year olds to them being two foot taller than me.

"Seeing them develop into such strong netballers is just fantastic. I think the hard work they've put in, not only this year but over the last few years, has come to fruition."

Kolora-Noorat's Lily Baker was named best on court as her side fell just short.

Robertson praised her side's calm in the face of the Power's momentum in the third and final quarters.

"When Kolora-Noorat came, when they were really pushing us the girls remained calm," she said.

"They didn't let that pressure affect their mentality.

"That's something we work on through the year, it's not just about the physical skills for us."
