The NRMA has called for an investigation into today's fuel price hikes, saying travellers have been unfairly targetted with price gouging.
The motoring body wants the Australian Consumer and Competition Commission to mount a probe into increases which it says are around 10 to 15 cents higher than they should be.
Peter Khoury from the NRMA says the price rises being seen across the country are out of the normal price cycle and need investigating.
"For reasons unexplained, the oil companies almost halved the cycle in the week leading up to Christmas," he said.
"So today, when there were no more kids at school and families have packed their bags and packed the cars and are heading away on holidays, the price has jumped when in fact they should have dropped." However, the ACCC says it regularly monitors petrol prices around holiday periods and has found the price movements to generally fit within the typically weekly or fortnightly price cycle.
"The increase in petrol prices in Sydney in the last 24 hours is consistent with the common retail petrol price cycles that regularly occur in Australia's largest cities," the ACCC said in a statement.
"The duration of the price cycle in Sydney has changed from seven days to up to 14 days.
As a result, the day on which prices rise changes from cycle to cycle." The ACCC says motorists may notice price movements more over holiday periods because a large number of motorists make long trips, using more petrol than usual.
