Weekly Fuel Price Report: 29 June – 5 July 2026

Published: 11 July 2026

Welcome to this week's fuel price update. Over the reporting period from 29 June to 5 July 2026, we have observed a comprehensive upward shift in both petrol and diesel prices across the country. Whether you are driving in a major urban centre or have travelled through regional areas, the cost of fuelling your vehicle has noticeably increased. We analyse the latest data below to help you navigate this rising market and optimise your fuel budget.

Reported fuel prices and forecast

• Widespread Increases: The national average for Unleaded 91 (U91) has climbed to 161.86 cents per litre (cpl), driven by aggressive price cycle jumps in major capitals.
• Capital City Extremes: Adelaide saw the most dramatic jump for U91, surging 11.23% (16.69 cpl) to average 155.13 cpl, yet it still managed to remain the cheapest capital city. Canberra recorded the most expensive U91 average at 167.69 cpl.
• Diesel Hikes: Diesel (DSL) drivers are facing steep increases, with the national average hitting 181.94 cpl. Canberra experienced a painful 10.65% increase in diesel prices (up 19.77 cpl), while Perth diesel jumped 9.24% (15.72 cpl).
• Premium Fuels: Premium unleaded options followed the broader market trend, with P95 and P98 rising by roughly 5% to 10% depending on the location, averaging 178.04 cpl and 186.90 cpl nationally.
• Forecast: Given the universal rising trend across the eastern seaboard and Western Australia, we expect retail prices to peak shortly. Motorists should anticipate elevated prices in the immediate short term before the discounting phase of the cycle begins.

Looking Ahead

Looking ahead over the next three to four weeks, we expect the current price spikes in major capitals like Sydney, Melbourne, Brisbane, and Adelaide to reach their zenith. As the retail price cycle turns, motorists should start to see a gradual discounting phase. If you haven't filled up yet, it may be wise to purchase only what you need for the next few days to avoid buying at the very top of the cycle.

For diesel drivers, the outlook is less cyclical. Sustained wholesale pressures and global factors suggest diesel prices will remain relatively firm in the coming weeks. We recommend that diesel drivers seize any local discounts they can recognise, rather than waiting for a substantial market drop.

Check prices before you fill

Fuel prices can move quickly between nearby stations. Use ' . App(\App\Services\SiteConfigService::class)->getSiteName() . ' to compare reported prices, update times and station locations before you choose where to fill.

The map is useful when you want to see nearby stations quickly. The list is useful when you want to sort by price, distance or fuel type before leaving home, work or the shops.

Use the app for saved stations, alerts and directions when you are out. Use the website at ' . Url('/map') . ' when planning on a larger screen.

Before buying a full tank, check whether the saving is worth the drive: compare the pump price, distance, update time and local price trend.

Conclusion

It has been a challenging week for the family budget with universal price rises across all major fuel types. However, by staying informed and tracking the local discounting cycles, there are still savings to be found. We will continue to analyse the data and keep you updated as the market evolves. Drive safely and check your local prices before you hit the road.
