Petrol Prices: Is a Price Rise Happening in 2026? What Australian Drivers Need to Know

For many Australian households, petrol costs aren’t just numbers on a price board — they’re a regular and pressing part of the weekly budget. As we settle into 2026, the question on motorists’ minds is simple but vital: Are petrol prices set to rise this year? The answer is nuanced — and depends on a complex mix of global markets, government policy, and domestic pricing dynamics.

Where Petrol Prices Stand Today

In late 2025, retail petrol prices in Australia were averaging around 178–180 cents per litre across the major cities — a level shaped by international crude prices, refining costs, and local wholesale and retail margins.

That figure reflects the steady recovery in fuel costs following the pandemic era, when prices plunged to historic lows before rebounding sharply over the past few years.

Despite this recovery, there were signs of slightly lower prices at the end of 2025, with some reports pointing to a noticeable drop at the pump in December 2025.

Global Oil Markets: The Primary Driver

Crude Oil Prices — The Big Variable

At the heart of petrol pricing is the price of crude oil on international markets. Crude oil makes up the lion’s share of the cost of petrol once it’s refined and delivered to Australian forecourts.

Recent global data suggest oil markets may stay relatively subdued in 2026:

• Some forecasts show Brent crude could average around US$55–$60 per barrel in 2026 — down from higher levels in recent years and in line with a global oversupply and weaker demand outlook.

• Other data sources point to volatility and uncertainty — events like geopolitical tensions, production decisions by OPEC countries, or supply shocks could still push prices higher.

What this means is that while some price forecasts expect subdued crude prices, oil markets remain unpredictable — and sudden changes could still ripple through to petrol prices at the bowser.

Could Petrol Prices Rise in 2026? The Case for Higher Prices

Yes — there are several reasons why petrol prices could rise at some point this year:

1. Global Supply Disruptions and Geopolitics

Oil markets are sensitive to geopolitical events, especially in major producing regions. Even if a price jump might not be immediate, traders and analysts warn that tensions or disruptions can quickly translate into higher oil and fuel costs.

2. Domestic Retail Pricing Behavior

Petrol retailers sometimes raise prices based on expected cost increases or during seasonal demand peaks, even if wholesale prices haven’t yet moved as much. In 2025, motoring groups warned of price hikes at the pump despite wholesale costs being steady.

3. Fuel Taxes and Excise Structure

Australian petrol prices include fuel excise and GST, which form a significant portion of the pump price and are indexed regularly. Unless excise rates change (which sometimes happens in annual tax adjustments), that tax component continues to add to the cost of each litre.

But There Are Also Downward Forces

It’s crucial to balance that with the reasons petrol prices might not rise — or could even edge lower:

1. Lower Global Oil Price Forecasts

As noted above, some global forecasts see oil prices easing or remaining relatively low throughout 2026 — which typically flows through into lower petrol costs over time.

2. Weakening Demand Trends

Fuel demand globally has softened in recent years, partly due to economic slowdowns and gradually rising adoption of electric vehicles. Some Australian industry commentary even suggests petrol prices could drop slightly in 2026 if demand remains weak.

3. Seasonal and Local Pricing Cycles

In Australia, petrol prices move in cycles — they rise and fall with short-term factors like seasonal travel demand. Despite longer-term trends, drivers often see temporary dips in prices, especially when crude prices are stable or falling.

What Influences Petrol Prices in Australia?

Understanding why petrol prices might rise requires unpacking the key elements that make up the pump price:

🔹 Global Crude Oil Prices

This is the biggest influence. Crude oil must be refined into petrol, and global supply-demand balances, OPEC decisions, geopolitical risks, and economic growth all sway crude prices.

🔹 Exchange Rates

Australia imports a significant portion of its refined fuel. A weaker Australian dollar makes imported petrol more expensive, even if crude prices are flat.

🔹 Refining and Distribution Margins

Refining costs and how much retailers charge can affect local petrol prices — and margins can fluctuate independent of crude prices.

🔹 Government Taxes

The petrol price includes federal fuel excise and the 10% GST, which together can add a substantial layer to the price drivers pay.

So, Will Petrol Prices Go Up in 2026?

The answer is: probably — but not necessarily everywhere or all the time.

Here’s a realistic scenario based on current data and expert forecasts:

✔ Some price rises are plausible

• Micro-spikes linked to geopolitics, seasonal demand, or stronger crude pricing.

• Retailers adjusting prices ahead of seasonal travel peaks.

• Indexed fuel excise adding incremental pressure.

✔ But sustained, steep increases are less certain

• Many oil price forecasts see flat to modestly lower crude pricing through 2026.

• Weak demand trends and EV adoption could blunt upward pressure.

• Local cycles mean temporary falls or flat stretches may balance short rises.

✔ Regional variation is likely

Urban and regional areas often see different pricing due to distribution costs, competition, and local supply conditions.

What Does This Mean for Australian Drivers?

Budgeting and Planning

Drivers should prepare for continued variability at the pump in 2026. Some months may bring relief with lower prices; others could see bumps — especially if crude markets tighten or demand surges seasonally.

Smart Fueling Habits

Cost-conscious motorists can still save by:

• Tracking price cycles through apps and sites that compare local prices.

• Filling up early in the week — historically cheaper than weekends.

• Using loyalty programs and fuel discounts where available.

Longer-Term Shifts

Over the long run, electrification of transport and changes in travel behaviour could reduce demand for petrol, eventually easing fuel price pressure. But that transition will take years, not months.

Bottom Line: What Aussies Should Expect in 2026

There’s no simple yes or no answer — but here’s the reality:

• Short-term price rises are possible due to market dynamics or global events.

• The broad trend isn’t clearly upward if crude prices stay subdued or fall.

• Fuel prices will remain volatile and influenced by many external factors.

• Motorists should budget for variability, not stability.

In a world where energy markets are increasingly interconnected and unpredictable, petrol prices in 2026 will reflect a balancing act between global oil fundamentals, local cost factors, and evolving demand patterns. Australian drivers may see ups and downs at the pump — but watching global signals and domestic pricing trends will help decipher what’s coming next.
