Already the current Australian Land Speed Record Hoder at 804km/h (500mph), McGlashan will soon make an attempt on the world record in the Aussie Invader 5R, a rocket-powered car 10 years in the making.
A life-size replica of the 16-metre Aussie Invader 5R will join McGlashan at the event, along with three members of the team that built the land-to-land missile.
Powered by a liquid oxygen and bio-kerosene rocket engine producing around 200,000hp (149,253kW), the 5R is capable of accelerating from 0-1000mph (1609km/h) in just 20 seconds.
In most cases, that's faster than a bullet - but still a good deal short of the now-retired NASA space shuttle's
Should it achieve its potential, the Aussie Invader 5R will brake the sound barrier one-and-a-half-times over, while smashing the 1223km/h (763mph) record set by Britain's Andy Green in 1997.
"Rosco's story and project is both unique and inspiring," Event Director, Russ Tyrie said.
"We know visitors will enjoy speaking with him and the Aussie Invader team to find out more about their next record attempt and seeing a replica of the soon-to-be most powerful car in the world, the Aussie Invader 5R."
McGlashan said the team is planning to begin active tests of the car next year, with an attempt at the 1000mph record to come after that.
If none of these numbers have astonished you, try this one on for size: "at 1000mph, we will be travelling the same speed the earth spins at the equator," McGlashan said.
