AIMEE van der Hulst broke a 30-year record with a leap of 1.57m at yesterday's All Schools Sports at Hamilton Oval.
The Warwick High School student broke the record for 14-year-olds of 1.54m set in 1982 by Kim Charles from the same school.
Aimee did not miss a jump until she attempted 1.59m.
It was a personal best and a good start to an athletics season Aimee hopes will continue well with a placing at the regionals.
She has represented Southern Downs for the past five years in high jump and recorded one win and two placings at regional level.
Assumption student Brodie Sharman ran 10.43secs for the 100m to break a record set in 1998 by Warwick High student Kurt Goodwin.
Brodie said he did not even check the record before his event, just wanting to run a personal best.
Jack Bannister, of Allora State School, extended the 14-year discus record of Matt Denny from 53.92m to 54.62m. It was a personal best by one metre.
