Electric vs. Petrol: Summer Road Trip Costs in Australia 2025?

Summer in Australia beckons with the promise of sun-drenched beaches, winding coastal roads, and unforgettable adventures. As we gear up for the 2025 summer road trip season, a crucial question weighs on the minds of many motorists: which is the more economical choice – electric or petrol? With fluctuating fuel prices and the increasing adoption of electric vehicles (EVs), making an informed decision can significantly impact your holiday budget.

The Great Australian Road Trip: Petrol vs. Electric – A Cost Analysis

Let's delve into a detailed comparison of the costs associated with petrol and electric vehicles, considering the realities of long-distance travel in Australia.

Upfront Costs: A Significant Hurdle for EVs?

While the long-term running costs of EVs are often touted as a major advantage, the initial purchase price remains a significant barrier for many Australians. Generally, EVs still command a higher price tag than their petrol-powered counterparts. However, government incentives and rebates can help to offset this initial investment. Thorough research into available incentives in your state or territory is highly recommended.

Fuelling vs. Charging: A Tale of Two Technologies

The most obvious difference lies in how these vehicles are “fuelled”. Petrol vehicles rely on readily available petrol stations across the country, offering convenience and quick refuelling times. Electric vehicles, on the other hand, require charging, which can be done at home, at public charging stations, or at dedicated fast-charging locations. The availability of charging infrastructure, particularly in remote areas, remains a crucial consideration for long-distance EV travel.

Understanding Petrol Prices in December 2025

Petrol prices in Australia are notoriously volatile, influenced by global events, exchange rates, and local market conditions. As of December 2025, prices vary considerably across capital cities. For instance, in Sydney, Unleaded 91 (U91) is currently averaging around 180.63 cpl, while Premium 98 (P98) sits at 205.08 cpl. Brisbane motorists are facing even higher prices, with U91 at 205.02 cpl and P98 at a hefty 228.95 cpl. Adelaide currently boasts some of the most competitive prices, making it potentially Australia's most affordable capital city for motorists. Diesel prices also show significant variation, with Canberra currently experiencing the highest prices at 202.9 cpl, compared to Adelaide's more palatable 185.96 cpl. These fluctuations highlight the importance of monitoring prices and strategically planning your fuel stops.

Interestingly, Unleaded 91 prices are currently 18.7% higher in Brisbane (205.02 cpl) compared to Perth (172.74 cpl). Premium 98 prices also show a large difference across states, with Brisbane (228.95 cpl) being 15.7% more expensive than Perth (197.81 cpl). In Sydney, Premium 95 (198.85 cpl) costs 10.1% more than Unleaded 91 (180.63 cpl). Additionally, Brisbane motorists can save 1.4% by choosing E10 (202.16 cpl) over Unleaded 91 (205.02 cpl).

Calculating Charging Costs for EVs

Charging costs for EVs depend on several factors, including the size of the battery, the charging rate, and the electricity tariff. Home charging is generally the most cost-effective option, especially if you have solar panels. Public charging stations, particularly fast-charging options, tend to be more expensive. It's crucial to research the charging networks along your planned route and understand their pricing structures. Many networks offer membership options that can provide discounted rates.

Fuel Efficiency vs. Energy Consumption: The Numbers Game

To accurately compare costs, we need to consider fuel efficiency (for petrol vehicles) and energy consumption (for EVs). Fuel efficiency is typically measured in litres per 100 kilometres (L/100km), while energy consumption is measured in kilowatt-hours per 100 kilometres (kWh/100km). These figures will vary depending on the vehicle model, driving conditions, and driving style. Consult the manufacturer's specifications for your vehicle to obtain accurate figures.

Maintenance and Servicing: The Long-Term View

Electric vehicles generally have lower maintenance costs than petrol vehicles. They have fewer moving parts, require less frequent servicing, and don't need oil changes or spark plug replacements. However, EV batteries will eventually need replacing, which can be a significant expense. Petrol vehicles, on the other hand, require more frequent servicing and are prone to wear and tear on components such as the engine, transmission, and exhaust system.

Practical Tips for Saving Money on Your Summer Road Trip

Regardless of whether you choose petrol or electric, here are some practical tips to help you minimise your travel expenses:

• Plan your route carefully: Avoid unnecessary detours and choose the most efficient route possible.
• Drive efficiently: Maintain a steady speed, avoid harsh acceleration and braking, and use cruise control where appropriate.
• Pack light: Excess weight reduces fuel efficiency (or increases energy consumption).
• Maintain your vehicle: Ensure your tyres are properly inflated and your vehicle is well-maintained.
• Shop around for fuel (or charging): Use apps and websites to compare prices and find the cheapest options along your route.

Conclusion: Making the Right Choice for Your Summer Adventure

The decision between electric and petrol for your 2025 summer road trip depends on a variety of factors, including your budget, travel distance, access to charging infrastructure, and personal preferences. While EVs offer the potential for lower running costs and reduced environmental impact, the higher upfront cost and charging limitations may be a deterrent for some. Petrol vehicles, on the other hand, offer greater convenience and range, but are subject to fluctuating fuel prices and higher maintenance costs.
