Motorcycling Australia has postponed the Yamaha Australian Off-Road Championship opening rounds to be held at Dungog this weekend.
Alternative dates for the Dungog rounds have yet to be announced.
“In consultation with key AORC event organisers nationally, Motorcycling Australia has made the joint decision that the AORC rounds one and two will not go ahead,” Motorcycling said in a statement.
“The Dungog area and surrounds have been and will continue to be affected by ongoing extreme weather events currently in place on the East Coast of New South Wales and Queensland.
“Presently, the tracks are unrideable and road access to the event is in doubt in line with current weather predictions.
“While we understand there may be frustrations surrounding the decision to postpone the event, we must ensure the reasonable safety of everyone involved in the AORC rounds,” the statement concluded.
