But he is worried his chance to compete at the 2016 Rio Olympics is in doubt, due to what he considers “unfair selection criteria”.

Turner has been Australia’s number one ranked double trap shooter for the past 18 months.

He competed at the World Cup in Germany in June; finished equal fifth in the men’s double trap at the Glasgow Commonwealth Games in July, and competed at the world championships in Spain the following month.

He went on take out the Australia Cup final in December with a world benchmark score of 140.

This year he has placed second at the national ISSF titles at Lake Macquarie (only behind an Italian shooter), and won the single barrel championship at the national DTL championships in Wagga, qualifying for the Mackintosh team (a competition against Commonwealth countries).

But Turner was not been selected to compete at the 2015 World Cup, held in Cyprus last week – and he is worried this will harm his chances of being selected for next year’s Olympic Games, as he says World Cup events are vital for Australia’s Olympic quota places.

Turner said he didn’t want to take anything away from Australia’s only double trap representative, James Willett, for his selection, but questioned why only one athlete was sent when three positions were available.

A Shooting Australia spokesperson said athletes must shoot a qualifying score at an endorsed selection event to be chosen for the World Cup team.

The spokesperson also said that Turner will have other opportunities – including the Oceania Championships this year, and events early next year – to qualify for the Australian team for Rio.

A dual Olympian (Sydney 2000 and Athens 2004), Turner firmly believes a “first-past-the-post” policy should suffice.

“Even being ranked number one doesn’t entitle me to attend world events,” Turner said.

“If they (Shooting Australia) won’t allow you to shoot, then you’re behind the eight-ball from the beginning.”

Turner appealed twice – unsuccessfully – to be included in the team, and attempted to take his case  to the Court of Arbitration for Sport.

“The base line is, any sport should be equal and fair,” he said.

“If they don’t believe that, then they’re out of touch.”

Shooting Australia’s selection policy for the 2015 World Cups states that its principal aims for selection for a 2015 World Cup are to provide Australia with the best possible chance of maximising the number of medals it can win in shooting events at the Rio Olympic Games and of gaining Olympic Games quota places; and to provide pre-elite athletes with an opportunity to compete at an international multi-discipline event for the purpose of accelerating their development.
