Petrol and diesel prices have increased after discounts to the fuel excise ended on Monday at the same time as escalating tensions in the Middle East led to a spike in the price of oil.
The national average cost of unleaded petrol was $1.82 a litre for July and the price had risen to $2.09 by Friday.
But staff at petrol stations were not wearing the same level of customer frustration as when the Iran-US war first broke out in February, Motor Trades Association of Australia executive director Bruce Billson said.
He told AAP Australians had been through such a price spike before.
"It's a calmer picture at the bowser than people might expect ... we're simply not seeing the panic-buying behaviour of previous spikes," Mr Billson said.
"There's a much better understanding this time of what's actually driving pump prices, and that means service station staff aren't wearing the same level of customer frustration."
Mr Billson said fuel supply in Australia had been steady.
"Australia is holding more fuel than it has in recent times, so the pressure isn't coming from availability," he said.
"It's the global oil price doing the work here, pushing prices up in Australia just as it is right across the world."
Energy Minister Chris Bowen will on Saturday announce latest supply levels in his first weekly update since the end to excise discounts.
The weekly address outlines the number of ships carrying oil to Australia and an update on domestic reserves for petrol, diesel, and jet fuel.
Mr Bowen last announced Australia had 43 days of petrol, 39 days of diesel and 34 days of jet fuel stockpiled.
The federal government's fuel excise cut, which reduced the price of fuel by 32c a litre in April, was wound back to 16c in July before being scrapped altogether on Monday.
