Supermarkets have stockpiled foodstuffs in anticipation of the impact the national truck strike could have on the availability of produce.
Up to 270,000 truck drivers across the country were expected to walk off the job today as part of a campaign by two transport lobby groups for a fairer go for drivers.
Mick Pattell, from the National Road Transport Forum, says drivers are facing increased costs and regulation, with the registration fees for a B-double set to rise from $8000 to $14,000.
"That's going to be an impost that’s going to be passed on to the consumer," he said.
There have been reports of some bulk buying at markets this morning to prepare for the worst, but Margie Osmond from the Australian National Retailers Association says everyone needs to "take a deep breath".
Ms Osmond says there is no indication the strike will be uniform in effect across the country, with the biggest impact expected to occur in Queensland.
