The drone attack on Saudi Arabia’s oil fields in combination with a weak Australian dollar and inconsistent pricing cycles has created what NRMA spokesman Peter Khoury called a “perfect storm”, causing petrol prices to skyrocket.The average price per litre for petrol in Sydney, Melbourne, Brisbane and Adelaide is peaking at $1.66 per litre. “That’s the highest we’ve seen in 11 years,” Khoury told a number of factors have converged to force the increase, Khoury said that some petrol stations are taking unfair advantage of the situation and gauging prices.”It is true that there are a number of stations out there that are charging as much as $1.73 to $1.75 per litre– they are simply ripping people off,” Khoury said.Given the inconsistency in the market, drivers are being advised to shop around.Luckily, the prices in most major cities besides Sydney are set to ease over the coming weeks.”There is relief in sight,” Khoury said, thanks to the flow on effect of world oil prices dropping this week.The bad news is that while petrol prices tend to increase in dramatic jumps, they decrease gradually, only falling about 1c per day.

Unlike the rest of the country, petrol prices in Sydney are expected to continue climbing over the coming days. This, Khoury said, is simply because of the pricing cycles.”It just happens the cycle is working against us right now,” he said.Petrol prices in Sydney, Melbourne, Brisbane and Adelaide rise and fall according to what Khoury called “inconsistent cycles”, meaning the length of each cycle changes.”The cycles that we have in these four cities are unique to Australia. Nowhere else fluctuates like that,” the NRMA spokesman said.Perth prices, on the other hand, fluctuate in a consistent seven-day cycle, with Monday always being the cheapest day to buy, and Tuesday the most expensive.Canberra, Hobart, and Darwin prices don’t change according to cycles and tend to be consistently higher due to the fact they are less competitive markets.
