Old Millfieldian Pamela Cookey led England's netball team to an historic series victory over Australia last week.
The 58-51 victory over the current world champions was only England's fifth-ever against their old rivals and completed a 3-0 series whitewash.
"We've really had that belief that we can go out and put in performances on the court [during this series]," said Cookey.
"Three-nil against Australia, the first time ever in English history, I'm so proud to be part of this."
The first match ended in a 58-53 victory for England at the University of Bath, with 40 current Millfield netballers making the trip to support their country.
A subsequent 51-49 victory at Wembley Arena completed the series win, with the whitewash wrapped up at the National Indoor Arena.
While still at the Street school, an uncapped 17-year- old Cookey was a surprise inclusion in the England squad for the 2002 Commonwealth Games in Manchester.
She missed out on competing due to injury, but went on to win bronze medals at the Melbourne 2006 and Delhi 2010 games.
Cookey was vice-captain during England's 2011 World Series victory and last May was named captain for the Europe Open Championships, which England also went on to win.
