Petrol prices are falling across several Australia state capitals ahead of the new year.

In Sydney, average fuel prices are 121.8 cents per litre and trending downwards, but there are bargains scattered across the city, according to the National Roads and Motorists Association.

The price has already dipped about 20 cents per litre since last week and will continue to fall up to 12 more cents.

“There’s a massive number of service stations on or just over $1,” NRMA spokesman Peter Khoury said.

“We should continue to see falls throughout the new year into next week and falls of about a cent or two cents every day.

“What we want people to do is just do their research before they fill up because even in those more expensive suburbs you will find bargains.”

Fuel costs are also falling in Melbourne, with an average price of 122.7 cents per litre.

“Melbourne and Sydney have been on par now for the last week to two weeks,” Mr Khoury said.

“We’re going to see Melbourne and Sydney continue to fall, Brisbane is now slowly starting to fall, and Adelaide was already at the bottom, and now it’s starting to go up.”

Adelaide petrol prices were now an average of 109 cents per litre and surging, so the best time to fill up was now, Mr Khoury said.

Meanwhile, Brisbane has an average price of 132.3 cents and going down.

“Brisbane was much higher because its low point was a couple of weeks ago,” Mr Khoury said.

“It went up and now it’s slowly starting to come back down.”

Perth prices are on average 132.7 cents per litre after peaking on Wednesday and are now trending downward.

Average petrol prices in Canberra, where the average price is 122.6 centres per litre, Darwin (115.8) and Hobart (123.9) were more stable because they were not driven by price cycles, Mr Khoury said.

But with a bit of shopping around, there are bargains to be had.

For example, the most expensive petrol in Sydney on Thursday was about 139.9 in Wetherill Park and the cheapest was 96.8 cents at Georges Hall.

Good deals were also in Fairfield at 97.9 cents and Greenacre 98.9 cents.

Mr Khoury advised people planning on filling up between now and next week to hold off as long as they could.

“The prices are just going to keep falling,” he said.

“But do your research if you do have to fill up now because obviously there are bargains to be found.”
