Motorists across the South East continue to feel the squeeze as petrol prices ease slightly off last week's peak

Data produced by the Australian Institute of Petroleum (AIP) shows for the week ending June 26, the national average price for 91-octane unleaded was 211.9 cents per litre.

This was just 0.6 cents per litre shy of the 212.5 cents per litre peak reached in March, before the fuel excise cut kicked in.

Diesel prices caused even more pain over the same period, with the national average sitting at 230.7 cents per litre.

Although prices have eased somewhat since, the advice for local motorists from RACQ's fuel expert Dr Ian Jeffreys is to hold off from filling up.

"The south east Queensland metropolitan markets are in the discounting phase of the price cycle so we advise motorists to hold off filling up, as prices will continue to fall over the coming days and into next week," Dr Jeffreys said.

"Motorists in Jimboomba should be aiming for a cheap price of 208 cents per litre so make sure you're using apps like RACQ's Fair Fuel Finder to track down the best deal you can.

"The Beaudesert ULP market does not follow the SEQ price cycle. However, Beaudesert motorists still need to be aware of the cycle, because on some days it will be cheaper to buy to close home and others to buy in Brisbane, Logan or the Gold Coast if they're travelling to these areas."

Although it may be tempting to travel into town to score cheaper fuel, Dr Jeffreys said motorists shouldn't make it their sole reason for travelling.

"In general, RACQ would encourage motorists to combine trips," he said.

"Before you travel to Brisbane, Logan or the Gold Coast check the price comparison sites because on some days, it'll be cheaper to buy fuel close to home and on others at your destination."

As of June 29, the cheapest fuel in the Jimboomba area can be found in Greenbank, where the service stations on Teviot Road are offering unleaded for 214.9 cents per litre.

The majority of service stations in Beaudesert are also offering unleaded for the same price, except for the Ampol station on Beaudesert-Nerang Road.

Diesel drivers in Jimboomba should also head for Teviot Road, as both service stations are selling diesel for 232.9 cents per litre, marginally less than retailers in Jimboomba.

The average price for diesel in Beaudesert is 234.9 cents per litre.

The price of diesel continues to climb, and Dr Jeffreys said this is likely to worsen as sanctions on Russia continue to bite.

"Daily average diesel prices continue to trend up across south east Queensland, with a new record reached yesterday of 235.4cpl for Greater Brisbane," he said.

"The ongoing war in Ukraine and the sanctions against Russia continue to put pressure on global prices and this is affecting the diesel price being paid at the bowser.

"As Russia was a major diesel producer diesel prices have been especially hard hit by the sanctions against Russia."
