However, prices are now creeping back up.
NRMA spokesperson Peter Khoury said increasing petrol prices reflected the ongoing volatility in wholesale oil prices.
He said oil prices jumped again last week, but prices had since stabilised.
Fuel prices at the pump in Melbourne had already spiked, Khoury said, with prices sitting at $1.89 a litre.
Sydney had increased around 6-7 cents in the past few days, with fuel prices sitting around $1.67 a litre.
Brisbane was around $1.78 a litre, on average, and Adelaide around $1.84 a litre.
“So, I guess the point is, prices are gonna go back up but not as high as the record highs that we saw.”
His final price prediction? In the next price cycle for the cities that have them, he expects unleaded prices to peak in the “high $1.80s” a litre.
