About 40 per cent of service stations are still selling regular unleaded at 222.9 cents per litre or higher, according to the NRMA.
Prices at Sydney petrol stations vary by up to 51 cents different, meaning shopping around could save more than $28 on a full tank.
The price is expected to drop to around 195 cents over the next two or three weeks in Sydney.
Around the nation, each capital city is at a different point in the price cycle but Melbourne, Adelaide and Hobart are the cities expected to keep rising.
NRMA spokesperson Peter Khoury said with many Australians expected to take this Friday off and make it an Anzac Day long weekend, finding the right place and time to fill up was critical.
“After Sydney broke its record for the highest average price for regular unleaded last week, Brisbane has now come close to doing the same at 231.7 cents per litre, it’s well past the point when Australians need some relief,” Khoury said.
The most expensive and cheapest countries on Earth for petrol
Khoury said families leaving Sydney should consider filling up outside the city as there were a number of regional locations that were cheaper.
The average capital city prices for regular unleaded are below.
