The discussions come amid a number of recent crashes and concerns about the layout of a track at the Harry Graham Drive facility.

Neville Turner - a 51-year-old, experienced motocross rider - died after he hit a tree during a social ride about 10.30am on Sunday.

The crash happened on a lower-speed practice track, which is a smaller version of the main racing circuit and located in a heavily-wooded area, the club said.

The Mercury has been made aware of at least two other recent serious-injury crashes on the same section of track.

One of them, in March, involved a teenage boy who broke his leg after he miscalculated a jump and was hit by another rider.

A person with links to the club, who spoke on the condition of anonymity, said there had been calls for the practice track's layout to be changed to improve safety.

"It's been brought up time and time again. People have been injured on that same part of the track, probably three helicopters this year to that part of the track and there's probably another 10 bad injuries on that track," the person said.

"The main track itself is very safe, but that track where that bloke got injured is very, very dangerous and everyone knows."

Club president Paul Treverrow denied suggestion the club had failed to act.

"I haven't heard any people talking to me directly about the track being dangerous," Mr Treverrow said.

"There hasn't been any communication to the club directly that the track is dangerous.

"We're always looking at improving safety in every aspect of all the circuits at the facility. That particular circuit has had some revisions in terms of jumps and layout in the last couple of months, due to a couple of accidents there."

Mr Treverrow said Mr Turner's death was the first fatality at the complex in more than two decades and people using the practice track were aware they were riding near large gum trees.

He said there were accidents on all the circuits and described the scene of Sunday's crash as "an unusual place for the accident to happen".

"We are at a bit of a loss, at this stage, as to what has happened," he said.

"He's obviously struck a tree but what's caused that obviously I can't comment on ... something's gone awry there."

Mr Turner was unconscious for some time and couldn't be revived, despite the efforts of an onsite medic and paramedics.

He was riding by himself at the time and there were only a couple of other riders on the track, Mr Treverrow said.

"Most of our accidents are typically on the main track," he said.

"We do get spates ... we'll call the helicopter about three times in three months and then we won't call them for 12 months.

"Everyone knows motorcycling, and particularly motocross, is a dangerous sport.

"Typically your injuries involve broken wrists and collarbones, and things like that. It's very uncommon to be killed in a dirt bike accident, unless you're out on the road on your dirt bike."

Mr Treverrow said Mr Turner was "quite experienced" and rode semi-regularly at the complex.

"It [his death] is absolutely devastating," he said.

Club officials are expected to meet on Tuesday or Wednesday to discuss the tragedy and ways to prevent a similar accident.
