SWIMMING: Allora swimmer Bailey Harm put his relay team in the lead with a brilliant third leg on the way to winning freestyle gold at the nationals.

He was part of the 11 years Queensland freestyle relay team which won gold at the School Sport Australia Swimming Championships in Melbourne.

The Queensland team was ranked second to New South Wales and was second when Bailey dived in as the third swimmer in the freestyle relay.

He made up ground on New South Wales and had Queensland a body length in front at the last change.

Queensland went on to win the gold medal on top of a gold medal win in the mixed medley relay where he swam the backstroke.

He also swam backstroke in the silver medal winning effort of the Queensland team in the boys medley relay.

Bailey now has five national medals after winning gold and silver in relays last year.

In individual events, Bailey made two finals and was sixth in 50m backstroke and seventh in 50m freestyle at the Melbourne Sports and Aquatic Centre.

He trained until April at the Allora pool under coach Andrew Fidge and has been travelled to Toowoomba three times a week to train under Fidge in a heated pool.

His coach also travelled to Melbourne for the three-day nationals last week.

Bailey headed home from Melbourne on Saturday and then won eight from eight in his races at the Darling Downs Short Course Championships at Fairholme Pool in Toowoomba on Sunday.

He is back at school this week at Scots PGC College and next week will compete in the Queensland Track and Field Championships.

He is in the 11 years high jump and has a best of 1.48m. He set a new record at this year's Scots PGC clan championships when he bettered the record by 13cm.
