Victoria's Daily Fuel Price Cap Is Now Law. Here Is Everything You Need to Know
As of today, March 10, 2026, Victorian service stations can no longer jack up petrol prices halfway through the day. The state's new daily fuel price cap has officially taken effect under Phase 2 of the Fair Fuel Plan, and it changes the game for every motorist in Victoria.
The timing could not be more relevant. With the Hormuz crisis pushing unleaded past $2 a litre in most of the country, Victorian drivers now have a tool that no other eastern state can match. Prices can go down during the day, but they cannot go up. That is the law.
Here is how it works, what it means for you, and why it matters right now more than ever.
How the Daily Price Cap Actually Works
The mechanics are straightforward.
Every day between 8:30am and 2pm, every fuel retailer in Victoria must submit the maximum price they intend to charge the following day for each fuel type. Unleaded, diesel, premium, E10, the lot. If they miss the 2pm deadline, yesterday's cap automatically rolls over.
By 4pm, those capped prices are published on the Servo Saver feature in the Service Victoria app. That means you can see tomorrow's maximum price at every servo in the state before you even leave work.
The cap kicks in at 6am the next morning and runs for 24 hours. During that window:
- The station can start the day at or below its submitted cap
- It can drop prices as many times as it likes
- Once it drops the price, it cannot raise it again until 6am the next day
- The price displayed on the board must match what customers are actually charged
This is the critical part. A station can begin the day at its cap, then drop to compete with the servo down the road. But once it drops, that is it. No sneaking the price back up at 3pm when people are filling up on the way home from work.
Why This Matters Right Now
Victoria's unleaded average is currently sitting at 206.8 cents per litre, with prices ranging from 150.0 cents at the cheapest stations to 374.0 cents at the most expensive. That is a spread of more than $2.24 per litre between the cheapest and dearest servo in the state.
Diesel is averaging 214.2 cents, premium 95 is at 224.4 cents, and premium 98 has hit 231.1 cents.
With the Hormuz crisis continuing to push global oil prices higher and Australian fuel costs rising by 31 cents in three weeks, the daily cap does not make fuel cheaper. What it does is stop the most predatory pricing behaviour: stations watching wholesale prices tick up during the day and immediately passing that through, or deliberately spiking prices during peak commute hours.
The Numbers: What You Could Save
According to ACCC data, Melbourne motorists who fill up at the lowest point of the price cycle could save up to $333 a year.
The daily cap makes that easier. Under the old system, you might spot a low price on your phone, drive to the station, and find it had already jumped 15 cents by the time you arrived. That cannot happen anymore.
Let us put some real numbers on it. Take a typical 50 litre tank:
| Scenario | Price Per Litre | Cost Per Fill | Annual Cost (weekly fills) |
|---|---|---|---|
| Filling at today's VIC average | 206.8 cents | $103.40 | $5,377 |
| Filling at cheapest available | 150.0 cents | $75.00 | $3,900 |
| Filling at peak | 250.0+ cents | $125.00+ | $6,500+ |
The difference between filling smart and filling blind is more than $1,400 a year. The daily cap, combined with the Servo Saver app, gives you the information and the price certainty to consistently land closer to the bottom of that range.
Over 1,500 Stations Must Comply
Every fuel retailer in Victoria is covered. That is more than 1,500 service stations across Melbourne, Geelong, Ballarat, Bendigo, the Latrobe Valley, and every regional town in between.
There are no exemptions for big chains or independents. BP, Shell, Ampol, United, 7-Eleven, Costco, and your local independent servo all have to play by the same rules.
The Penalties Are Serious
This is not a suggestion. Consumer Affairs Victoria has expanded enforcement powers and they have made clear they intend to use them.
- Infringement notice: Over $3,000 per breach
- Court prosecution: Penalties exceeding $24,000 plus potential conviction
- Failing to register before selling fuel is a separate offence
Retailers also have to update their reported prices within 30 minutes of any change and notify Consumer Affairs when a fuel type becomes temporarily unavailable.
For independent operators, this means getting daily pricing procedures right from day one. Missing the 2pm submission window, failing to update a price drop within 30 minutes, or charging more than the submitted cap could each attract a separate fine.
How Victoria Compares to Other States
Victoria was actually the last state in Australia to introduce mandatory fuel price reporting. Here is how the landscape now looks:
Western Australia has run FuelWatch since 2001. It is the closest comparison to what Victoria has just introduced. WA retailers submit next day prices by 2pm, and those prices are locked for 24 hours from 6am. Sound familiar? Victoria's system is modelled heavily on FuelWatch, and WA's results speak for themselves. Western Australia currently has the lowest average unleaded price in the country at 198.1 cents per litre.
New South Wales has the FuelCheck app, which requires real time price reporting but does not cap daily prices. NSW unleaded averages 211.8 cents.
Queensland has mandatory reporting through the QLD Globe system. No daily cap. Average unleaded: 226.7 cents.
South Australia requires real time reporting. No daily cap. Average unleaded: 227.5 cents.
The pattern is worth noting. WA, the state with the most similar transparency and cap system to what Victoria just introduced, consistently has the lowest prices on the eastern seaboard. Correlation is not causation, but the data is hard to ignore.
What Servo Saver Does for You
The Servo Saver feature launched inside the Service Victoria app back in October 2025 for Phase 1, which covered real time price reporting.
Phase 2, which starts today, adds the ability to see tomorrow's maximum price from 4pm each afternoon. That means you can:
- Open the app at 4pm and see every station's cap for tomorrow
- Compare prices across your commute route or suburb
- Plan when and where to fill up with certainty
- If a station drops its price during the day, you know it cannot go back up
- A station cannot watch the morning news about oil prices and immediately hike its afternoon price
- Commuters will not get ambushed by a 15 cent jump between their morning drive past and their afternoon fill up
- The gap between the cheapest and most expensive station should narrow, because the cap creates a competitive race to the bottom rather than a race to exploit afternoon demand
The app is independent. It is not funded by advertisers and treats every station equally, whether it is a multinational chain or a family run independent.
What the Premier Said
Premier Jacinta Allan framed the changes squarely as a cost of living measure.
"To help you save money at the servo, we will require fuel companies to publicly report their price changes the day before and lock them into that price for 24 hours," she said.
"You know how much fuel prices fluctuate. Under our plan, you can find out tomorrow's fuel price at every single servo on your route to work and make your decisions accordingly."
"We know this won't change everything for families who are doing it tough, but these savings can add up to hundreds of dollars a year."
Consumer Affairs Minister Nick Staikos said the plan was about shifting the balance of power.
"We want to give families more power at the bowser. We're also keeping multinational fuel companies transparent about the prices they set and the deals they promote."
Industry Reaction
Not everyone is on board. The Australasian Convenience and Petroleum Marketers Association (ACAPMA), which represents fuel retailers, has supported mandatory reporting but pushed back on the price freeze component. The industry body warned that caps "could inadvertently reduce competition in the fuel market, which could drive up average fuel prices."
The argument goes like this: if stations know they cannot adjust prices during the day, they may set their caps higher as a buffer, particularly during volatile periods like the current Hormuz crisis. Whether that plays out in practice remains to be seen. WA's 25 year experience with FuelWatch suggests the competitive pressure to set low caps tends to outweigh the temptation to pad them.
The Bigger Picture: Timing and the Hormuz Crisis
The Fair Fuel Plan was announced and legislated well before anyone was thinking about the Strait of Hormuz. But its launch today lands in the middle of the most volatile fuel market Australia has faced since 2022.
With crude oil above $100 a barrel and wholesale prices still climbing, Victorian motorists are going to see high numbers on the board for a while regardless of what regulatory framework is in place. The cap does not control the base price. What it controls is the behaviour around that price.
In practical terms, it means:
As we noted in our analysis of the ACCC's fuel brief, the federal government is also ramping up pressure on fuel pricing behaviour. Victoria's daily cap is the strongest state level intervention yet.
How to Make the Most of It
Here is how to use the new system to your advantage.
Check Servo Saver at 4pm. That is when tomorrow's caps are published. Plan your fill up around the lowest cap on your route.
Fill up in the morning. The cap is at its maximum at 6am and can only go down from there. But if competitive pressure pushes prices down during the day, filling up later could save you more.
Compare across the day. If you spot a station that has dropped well below its cap, fill up there. It cannot raise the price again that day.
Use Petrolmate alongside Servo Saver. We track prices from official government APIs and community sources across every Victorian station. Our near me tool shows you the cheapest fuel right now, and our price trends page helps you understand whether today is a good day to fill up or whether waiting might save you more.
Stack your discounts. The daily cap makes discount stacking even more effective. A 4 cent supermarket voucher off a station that has already dropped its price below cap gives you the best of both worlds.
What Happens Next
Consumer Affairs Victoria has said it will be actively monitoring compliance from day one. Early enforcement action against stations that breach the cap would send a strong signal to the industry.
The real test will come over the next few months as the Hormuz situation plays out. If wholesale prices continue to climb, the daily cap will be tested in exactly the conditions it was designed for: preventing retailers from exploiting volatility to gouge at the pump.
We will be tracking the impact on Victorian prices closely. You can follow live prices on our Victoria fuel prices page or check what is happening at your local station using the map.
