Only two boys and two girls from each state were selected to compete in the championships, which are for Little Athletics participants under 15 years of age.

Edgerton and Bush were two of six athletes shortlisted for the Victorian team after strong performances at the State Multi-Event Championships in February.

The pair participated in several training sessions in Melbourne with Victorian selectors after the state event.

Bush and Edgerton were told they had been selected for the four-person team on Sunday.

Events at the championships are the 100 metres, 800 metres, 90-metre hurdles for girls and 100-metre hurdles for boys, long jump, discus and a mixed 4x100-metre relay.

Competitors must complete all events, which tests areas of weakness as well as strength.

Edgerton lives in the Wimmera and trained in Horsham before transferring to the Camberwell-Malvern Little Athletics Centre in Melbourne.

Bush lives and trains in Horsham.

They are only the second and third Wimmera athletes to qualify for the Victorian team, after Sophie Hutchinson in 2009.

Horsham athletics coach Ricky Price said it was a superb effort for the pair to make up half the Victorian team.

He said both had been training hard for the opportunity.

“I had the goal for them after last year’s state multis – and they did too – of making this team,” he said

“Last year Andy was third at the state multis and Anna was fourth, so we discussed it and it’s really been a 12-month goal.

“This definitely hasn’t happened by chance.”

Edgerton said he had his sights set on the championships after making a Victorian under-13 squad two years ago.

“In the under-13s you work with the two under-15 competitors and I thought it would be good to represent Victoria again and become a mentor for the under-13s,” he said.

“I’ve been training very hard for it for the past couple of months so I’m prepared.”

Price said both athletes were working hard to improve their weaker events.

“Anna is standing in pretty good stead to be up in the top few – the discus is probably her weak link, but she’s been doing a lot of training and improved quite a bit in the past few weeks,” he said.

“Andy had to really work on his hurdles in particular but he’s coming along pretty well there.

“It’s hard to know where he fits in with the rest of it, but he’ll do well in events such as the 100 metres, long jump and 800 metres.”

The championships are likely to be Bush and Edgerton’s last Little Athletics competition.

Both will be eligible to compete in under-16 Little Athletics events next season, but Price said that was unlikely.

“You can go on and do Little Athletics in under-16s, but they don’t generally do it, so this is probably the last event they’ll ever do of Little Athletics,” he said.

“They’ve both had outstanding careers in Little Aths and are certainly two of the best athletes who have gone through Horsham.”
