Back-to-back Maitland Sportsperson of the Year and Australia’s youngest Paralympic ­medallist Maddi Elliott will compete alongside fellow teenagers Abbey Harkin and Matthew Pender, the 2012 and 2013 Maitland Junior Sportsperson of the Year recipients respectively.

They will contest a combined 21 events over the next six days, with finals being televised nationally each night. 

Elliott will kick-start the meeting, which ­doubles as Commonwealth Games trials for Glasgow later this year, with the heats of the women’s multi-class 100 metre breaststroke at 10am at Chandler’s Brisbane Aquatic Centre.

This will be followed later today by ­preliminaries of the 50m freestyle event which Elliott, who has cerebral palsy, holds the S8 world record for with a time of 30.28 seconds.

The 15-year-old from Gillieston Heights ­continues her busy schedule tomorrow with the 100m freestyle. On Thursday she has the 50m backstroke, Friday delivers the triple of 100m backstroke, 100m breaststroke and 200m freestyle while she wraps up the carnival on the weekend with the 400m freestyle and 50m butterfly on Saturday and the 100m butterfly and 50m breaststroke on Sunday.

Elliott’s former Novocastrian Swimming Club teammate Abbey Harkin will compete at 

the Australian championships under the Ravenswood banner after shifting schools to Pymble Ladies College at the start of the year.

The 15-year-old, formally of Louth Park, has six races to contend across four days.

Harkin begins with the women’s 400m ­individual medley and 50m breaststroke today, follows with the 100m backstroke and 200m breaststroke tomorrow and Thursday ­respectively before ending on Friday with the 200m IM and 100m breaststroke.

Pender, 17 of Aberglasslyn, has a less ­demanding program with three events spaced evenly between Friday and Sunday. 

The West Wallsend Swimming Club ­representative will begin his campaign with the 100m butterfly, continue with the 200m ­backstroke and finish with the 200 IM.

Pender, Harkin and Elliott will swim alongside the likes of James Magnussen, Emily Seebohm, sisters Cate and Bronte Campbell, as well as Hunter product Thomas Fraser-Holmes.

The championships will be shown on ONE from 7.30pm.
