GT Academy's first casualties

After three days of competition for the Nissan GT Academy international race camp at the Silverstone Grand Prix circuit in the UK, half the video-gaming hopefuls have been sent packing, their dreams of becoming professional race drivers dashed.

Corey Creed and Tyler Blackburn were the first locals eliminated, followed by Simon Feigl who lost out after the 370Z gymkhana challenge.

Starting day four, three Aussies remain, Matt Simmons, Elliott Schutte and Nick Dalton.

The winner of GT Academy 2015 will be decided early Thursday morning, August 12, Australian time.

An Australian has yet to win the competition, coming very close last year, as the runner up.

The Nissan GT Academy is a competition where every day gamers who nailed hot laps on the Playstation video game Gran Turismo 6, and performed strongly at their national finals, have a chance to win a professional racing contract with Nissan.

Valued at around one million-dollars, former winners have gone on to win prestigious races such as the Bathurst 12-Hour and world's most famous sports car race, Le Mans 24 Hours, in the LMP2 class.

In total 15 contestants were sent home, from rival countries vying with the Australians for the sole race contract, including North Africa, Mexico, Turkey and the USA.

"At this stage it's not life changing but no one wants to go home first. It gets a lot harder from here," said Rob Barff, GT Academy International head judge.

Rick Kelly, Nissan Motorsport V8 Supercars racer and mentor to Team Australia also had his say.

"This is a chance of a lifetime; they've all worked so hard to come over to Silverstone so to have everything on the line and be eliminated this morning was tough," said Kelly.

Can Australia break through for its maiden GT Academy win? Stay tuned for the result later in the week.
