Young Gubecka secures big win at Aussie swim champs

TEEN sensation Chelsea Gubecka has again shown why she is one of the country's most exciting prospects after producing a commanding performance in the 1500m final at the national championships in Adelaide.

The 14-year-old Queensland student dominated last night's race, clocking 16:22.351sec and finishing 29 seconds ahead of South Australia's Leah Cutting.

The nationals double as the selection trials for this year's world championships in Barcelona, but the women's 1500m will not be raced at the July-August event.

However, Gubecka has already qualified for the world championships after capturing the Australian open water title this year by beating dual Olympian Melissa Gorman.

Gubecka's time in the 1500m final was 21 seconds outside Gorman's Commonwealth and Australian records.

Gold Coaster Bonny Macdonald finished third in 16:56.97.

In the 200m freestyle semi-finals, Sunshine Coast product Brittany Elmslie was quickest in 1:57.30.

Another Coast product, London Olympics gold medallist Melanie Schlanger, was sixth quickest (1:58.12).
