As Meares' world team sprint partner McCulloch has enjoyed international success, but she has never defeated Meares head-to-head and showed her desire to do so by flying past Kassandra Kell to claim the crown two races to nil in the final.

McCulloch, 22, had set a new championship record in qualifying with a time of 11.383sec for the flying 200m, beating Meares' 11.390 in 2007, and will now face up to Meares at the world titles in Copenhagen next month.

"There is obviously a little bit of honour to uphold here and I have put a little bit of pressure on myself too, but I really wanted to come out here and stamp my authority and put a good time on the board which I did, so I am very happy," said McCulloch.

South Australia claimed the men's 4000m team pursuit title with a blistering run led by individual pursuit specialists Jack Bobridge and Rohan Dennis.

The SA team's time of 4:00.417 was a new championship record.

It left defending champions Western Australia scurrying hopelessly in their wake and also made it a second title of the week for Bobridge, after he had become the second fastest pursuit rider of all time - only Briton Chris Boardman has been faster - on the way to winning gold in the individual classification.

In a neat tactical ploy, SA's team included Australian junior 1km time trial champion James Glasspool, who led off the quartet at breakneck speed before dropping off to leave his teammates to ride strongly the rest of the way.
