Apps That Track Daily Oil Price Changes

Filling up your car has never felt quite as painful as it does in 2026. By April, regular unleaded across Sydney hit over 225 cents per litre, diesel surged past $3.00 in some states, and the Australian Government moved to cut fuel excise by 50 per cent just to take the edge off. If you're not using some kind of price-tracking tool right now, you're almost certainly overpaying ,sometimes by 20 to 40 cents per litre compared to what someone a kilometre down the road is paying.

The good news is that Australians have access to some of the best fuel price transparency tools in the world. A combination of government-mandated reporting schemes and independently developed apps means that near real-time pricing data is available in almost every state and territory. The ACCC itself publicly encourages drivers to use these apps ,their own research consistently shows that consumers can save meaningful money simply by shopping around using the data that's freely available.

But with a dozen or more apps on offer, each with different coverage, accuracy levels, and features, it helps to know which one is actually worth installing. This guide covers every significant option, state by state, so you can find the right tool for wherever you are.

Why Fuel Prices Vary So Much ,and Why This Matters

Before diving into the apps, it's worth understanding why prices vary so dramatically between stations, suburbs, and days. In Australia's five largest cities ,Sydney, Melbourne, Brisbane, Adelaide, and Perth ,fuel retailers operate on what the ACCC calls a price cycle. Prices rise sharply over a short period, then fall gradually over a longer period, before the cycle repeats. In Sydney, these cycles can span 1–2 weeks, and the difference between the peak and trough of a cycle can be 40 cents per litre or more.

On top of the cycles, individual stations set their own prices and there can be significant variation between stations in the same suburb. The ACCC's own research found that in Sydney, the range between the highest and lowest-priced major retailer can vary by over 13 cents per litre. In Brisbane, that spread can be even wider on some days. For a 60-litre tank, that's a $7–$8 difference for exactly the same product.

Local competition, the proximity of supermarket-linked stations (Woolworths, Coles), and whether a station is on a major highway or tucked away in a suburb all affect pricing. Fuel price apps cut through all of that by showing you exactly what's available, right now, in your area.

How Much Can You Actually Save?

The ACCC estimates that consistently shopping around using a fuel price app can save a regular driver $10–$20 per tank. For a family filling up once a week, that's $520–$1,040 per year ,just from checking your phone before you pull into a servo.

App Deep-Dives ,The Ones Worth Installing First

PetrolSpy ,The Best All-Rounder

If you only install one app, most independent tests and reviews point to PetrolSpy as the most consistently accurate and useful option available to Australian drivers. It covers all states and territories, sources data from government mandatory reporting schemes where available (NSW, WA, QLD, TAS, NT), and uses crowd-sourced submissions for the remaining regions.

What makes it stand out in independent testing is its accuracy rate ,Choice magazine testing found it accurate 100% of the time in QLD (sourcing from mandatory reporting) and 90% in NSW. It shows prices on a map view, highlights the cheapest station in your current map view, allows filtering by fuel type (unleaded, E10, premium, diesel, LPG), and sends notifications when it's the best time to buy during a price cycle.

It's free on iOS and Android, and available as a website (petrolspy.com.au) for desktop or mobile browser use. There are ads, which some users find annoying, but the core functionality is genuinely useful.

•       Best for: Drivers in any state who want one reliable, consistent app across all their travels

•       Platform: iOS, Android, Web ,petrolspy.com.au

FuelCheck NSW ,The Best for NSW and ACT Drivers

For anyone in New South Wales or the Australian Capital Territory, FuelCheck NSW is the standout choice ,and it's run directly by the NSW Government. Over 2,000 service stations upload their prices in real time whenever they change, with no financial incentive to report falsely. The result is a database that's genuinely accurate and genuinely real-time.

The app is clean, simple, and completely ad-free. You don't need to create an account. You can filter by fuel type and brand, view all stations on a map, or switch to a list view sorted by price or distance. For NSW and ACT drivers, there's no reason to use anything else ,the data quality here is the best available in any Australian state.

•       Best for: Anyone in NSW or ACT ,the most accurate data, no frills, no ads

•       Platform: iOS, Android, Web ,fuelcheck.nsw.gov.au

FuelWatch WA ,The Best for Western Australian Drivers

Western Australia has some of the most consumer-friendly fuel pricing laws in the country. FuelWatch is the WA Government scheme that requires all fuel retailers to lock in their prices for a full 24 hours and submit the next day's prices by 2pm each afternoon. By 4pm, those prices are publicly visible ,meaning you can plan exactly where to fill up tomorrow before you even leave home tonight.

FuelWatch doesn't have a standalone app, but the mobile-optimised website (fuelwatch.wa.gov.au) works well on phones and tablets. The ServiceWA app also integrates FuelWatch data. The 24-hour price lock-in is unique to WA and makes comparison significantly simpler than in states where prices can change multiple times a day.

FuelWatch also offers an email subscription service with daily price alerts ,with over 9,500 subscribers as of 2024, it's clearly a well-used feature.

•       Best for: WA drivers ,the predictability of next-day prices is a genuine advantage

•       Platform: Web (mobile-friendly) ,fuelwatch.wa.gov.au | Also available via ServiceWA app

MotorMouth ,The Colour-Coded Price Guide

MotorMouth was Australia's first dedicated fuel price app and it remains one of the more distinctive options available. What sets it apart is its colour-coded pricing system ,green stations are offering a good price for the current point in the cycle, yellow is borderline, and red means you're overpaying relative to where prices should be. This makes it immediately intuitive, even if you don't know the local price cycle pattern well.

MotorMouth pulls data from mandatory government databases where available and supplements with community submissions. It covers around 4,500 service stations nationally. One quirk to be aware of: without a registered account, the app limits how many station prices you can see ,but registration is free. The Brisbane-based team behind it has been building and refining the product for years, and the accuracy in major cities is generally solid.

•       Best for: Buyers who want intuitive 'is this a good price?' guidance rather than just raw data

•       Platform: iOS, Android, Web ,motormouth.com.au

RACQ Fair Fuel ,Best for Queensland Drivers

The RACQ (Royal Automobile Club of Queensland) runs its own fuel price tool specifically tuned to Queensland's market. The Fair Fuel Price finder not only shows current prices at stations near you, but also provides guidance on whether prices are currently at a good point in the cycle ,telling you if it's a smart time to fill up or if it's worth waiting a few days for prices to come down.

This cycle prediction feature is particularly useful in south-east Queensland, where price cycles are pronounced and predictable. The app covers regional Queensland too, with pricing guidance based on what RACQ considers a reasonable margin above wholesale costs for regional areas.

•       Best for: Queensland drivers, particularly in south-east QLD, who want cycle-aware buying advice

•       Platform: iOS, Android ,available through the RACQ app | racq.com.au/fuel-prices

My NRMA ,Best for Members

The My NRMA app includes a fuel finder tool that shows real-time prices near your location, and for NRMA members, it unlocks up to 5 cents per litre discount at participating Ampol stations through the app's wallet feature. If you're already an NRMA member (or considering joining), this is a no-brainer addition to your phone.

The NRMA also publishes weekly fuel reports that explain the current state of Sydney's price cycle and what's influencing prices nationally ,useful context if you want to understand not just where prices are now, but where they're likely to head.

•       Best for: NRMA members, NSW-based drivers, anyone using Ampol stations regularly

•       Platform: iOS, Android ,mynrma.com.au

Servo Saver ,New for Victorian Drivers

Victoria was a relative latecomer to mandatory fuel price reporting, introducing the scheme in August 2025. Since March 2026, Victoria also has daily maximum price caps in place ,a significant consumer protection measure. The Servo Saver feature, built into the Service Victoria app, is the official way to access this data.

It's still relatively new and doesn't yet have the depth of functionality of apps like PetrolSpy or MotorMouth ,but as Victoria's mandatory reporting matures and more data flows in, it should become increasingly reliable. For now, Victorian drivers using the Servo Saver app alongside PetrolSpy will have the most complete picture.

•       Best for: Victorian drivers wanting an ad-free government tool; best used alongside PetrolSpy

•       Platform: Available via the Service Victoria app ,service.vic.gov.au

GasBuddy ,Good for Regional Areas

Originally an American app, GasBuddy has developed a meaningful Australian user base and is particularly noted for having better coverage in regional and rural areas than some of the government-data-driven apps. Its crowd-sourced model means that as long as enough people in an area are using and contributing to it, you'll get accurate local data even in towns without mandatory reporting.

It's not the most accurate in major cities where government-sourced apps have an edge, but for drivers who regularly travel to regional areas where FuelCheck or FuelWatch data doesn't reach, GasBuddy fills an important gap.

•       Best for: Regional and rural drivers, road trips, anyone travelling to areas outside major city coverage

•       Platform: iOS, Android, Web ,gasbuddy.com

How to Use These Apps to Actually Save Money

Having the app is one thing. Knowing how to use it strategically is what actually puts money back in your pocket. Here are the habits that make a real difference:

Understand Your Local Price Cycle

In Sydney, Melbourne, Brisbane, Adelaide, and Perth, prices follow predictable cycles. Most apps will show you a graph of the past 30–45 days of average prices ,study it. Once you recognise where you are in the cycle, you can time your fill-ups to land near the bottom. In Sydney, the cycle typically spans about 7–10 days. Filling up at the low point vs the high point of a cycle can save you 30–40 cents per litre.

Set Price Alerts

PetrolSpy, MotorMouth, and the NRMA app all allow you to set price alerts for specific fuel grades in your area. When the price drops below your nominated threshold, you get a push notification. This is the laziest possible version of fuel cost management and it works ,you don't have to remember to check, the app tells you when it's time to fill up.

Check Before You Leave, Not When You're Already Running Low

The best time to check a fuel price app is when you still have enough fuel to get to a cheaper station. If you wait until you're on the empty light, you're going to fill up at whatever servo is nearest and pay whatever they're charging. Having a rough idea of where the cheap spots are in your suburb or on your regular routes means you can plan around them.

Use Filters Wisely

Most apps let you filter by fuel type ,make sure you're looking at the right grade for your car. E10 is often cheapest but not all vehicles can run it efficiently. Premium 95 and 98 will always be more expensive, but the difference between the cheapest and most expensive stations for premium can be just as large as for regular unleaded. Filtering to your exact fuel type gives you an accurate comparison.

Don't Just Chase the Cheapest ,Consider the Drive

A station 5 km out of your way at 10 cents per litre cheaper than your local might sound good, but the extra distance eats into the saving. For a 40-litre fill, you'd save $4 but potentially use $2–$3 in extra fuel getting there. Within your normal route or suburb, any station 10+ cents cheaper is genuinely worth using.

What the ACCC Says ,Why These Apps Matter More Than Ever

The ACCC has been monitoring Australian fuel prices since 2001 and publishes detailed quarterly reports on market behaviour. In response to the current period of elevated prices driven by Middle East conflict and global crude market movements, the ACCC has been publishing weekly monitoring updates ,something it only does in periods of significant market stress.

The regulator's consistent advice is clear: use the apps. Their own research confirms that across all fuel types, consumers who actively shop around using price tools pay meaningfully less than those who don't. The ACCC also monitors retail price behaviour to ensure that retailers aren't inflating prices beyond what global input cost movements would justify ,and it has shown it will act when they do. In February 2026, the Federal Court ordered Mobil to pay $16 million in penalties for making false or misleading statements about fuel prices at nine Queensland stations.

The bottom line from the regulator's perspective: Australian fuel markets are competitive enough that shopping around works ,and these apps are the practical tool for doing it.

Frequently Asked Questions

Are fuel price apps accurate in regional and rural Australia?

Accuracy varies significantly depending on where you are. In states with mandatory price reporting ,NSW, WA, QLD, TAS, and NT ,apps that source data from the government databases (PetrolSpy, FuelCheck, FuelWatch) are highly accurate in both metropolitan and regional areas covered by the scheme. In Victoria and South Australia, where mandatory reporting is newer or less comprehensive, regional accuracy drops. For areas beyond the reporting schemes, crowd-sourced apps like GasBuddy and MotorMouth rely on user submissions, which means accuracy depends on how active the local user base is. In many remote areas, data may be hours or days old. For serious regional travel, FuelWatch (WA) and the government apps for each state are your best starting point, with GasBuddy as backup for the gaps.

Do these apps work for diesel and LPG, not just unleaded?

Most of the major apps cover multiple fuel types. PetrolSpy, MotorMouth, FuelCheck NSW, and FuelWatch WA all allow you to filter by fuel type including E10, unleaded 91, premium 95, premium 98, diesel, and in some cases LPG. Coverage for diesel is particularly strong in states with mandatory reporting, since the same reporting obligation applies to all fuel types. LPG coverage is patchier as the number of stations offering it has declined significantly over the past decade. If diesel is your primary interest ,as it would be for commercial operators, tradies, and 4WD owners ,check whether your chosen app shows diesel prices prominently. PetrolSpy and FuelWatch are the strongest options for diesel tracking nationally.

Can I track crude oil prices (not just pump prices) on these apps?

The apps covered in this guide focus on retail pump prices at local service stations ,what you'd actually pay at the bowser. For tracking crude oil and international refined fuel benchmarks that drive Australian retail prices, these apps aren't the right tool. The ACCC publishes weekly fuel price monitoring updates (accc.gov.au) during periods of market stress that include international crude price movements and their expected flow-through to Australian retail prices. For live crude oil price data, financial data platforms like Bloomberg, Reuters, or the Oil Price website (oilprice.com) are more appropriate. The NRMA's weekly fuel report also explains the current international context in plain language ,worth reading if you want to understand why pump prices are moving the way they are.

The Bottom Line

The short answer is yes ,there are excellent apps for tracking local fuel price changes in Australia, and they genuinely work. The combination of government-mandated price reporting (in most states), independent apps that aggregate that data cleanly, and the predictable price cycle patterns in major cities means that an informed driver with the right app can consistently pay 10–40 cents per litre less than someone who just pulls into the nearest servo without checking.

Start with the government app for your state ,FuelCheck NSW, FuelWatch WA, FuelCheck TAS, or Servo Saver in Victoria. Add PetrolSpy as your nationwide backup and for any travel interstate. If you're a Queensland driver, the RACQ app adds useful cycle prediction on top of raw price data. And if you regularly drive to regional areas, make sure GasBuddy is also on your phone.

At a time when every trip to the servo stings a little more than it used to, these tools are one of the few genuinely free, genuinely effective ways to keep more money in your wallet.
