Australian Fuel Prices & Trip Planning Guide
Whether you're planning a weekend road trip up the coast, managing a fleet of commercial utes, or cross-verifying ground logistics for an aerodrome flight, predicting your fuel expenses accurately is critical. Australian fuel prices fluctuate significantly across state jurisdictions and weekly price cycles.
Our advanced trip fuel calculator automatically handles return journeys, road tolls, group passenger splits, and metric/imperial fuel economy conversions (L/100km, km/L, MPG).
Unleaded & Premium Petrol (U91, 95, 98)
The majority of Australian passenger cars run on Unleaded 91 or E10. European vehicles, turbos, and performance cars often require Premium Unleaded (95 or 98 RON). Premium fuels cost more per litre but can provide cleaner burns and marginal efficiency gains.
Diesel & Heavy 4WDs
Diesel is heavily utilized across Australia for 4x4s, touring rigs, and commercial transport. While diesel engines deliver superior fuel economy over long distances, diesel pricing follows global wholesale trends rather than consumer retail cycles.
Aviation Fuel in Australia: Avgas 100LL & Jet A-1
Posted Airfield Prices (PAP), Carnet Cards & Aerodrome Refuelling
Unlike automotive petrol which is publicly published under mandatory retail price monitoring schemes, aviation fuel (Avgas 100LL and Jet A-1) is not tracked by a single public API in Australia. Aviation fuel operates on posted airfield prices (PAP) set by wholesale distributors and aerodrome fixed-base operators (FBOs).
General aviation pilots operating out of secondary aerodromes like Jandakot (YPJT), Bankstown (YSBK), Moorabbin (YMMB), and Archerfield (YBAF) primarily refuel using 24/7 automated bowsers via:
- Viva Energy Aviation & Fuel2Sky Carnet ↗ — Major supplier of Avgas 100LL and Jet A-1 across Australian regional & capital airports.
- Air BP & myairbp Portal ↗ — Global aviation fuel card system for flight schools, charter operators, and private pilots.
- Airservices Australia ERSA (En Route Supplement) ↗ — Official directory of aerodrome fuel services, contact frequencies, and call-out fees.

Frequently Asked Questions
How is fuel cost calculated for a trip in Australia?
Fuel cost is calculated using the formula: (Distance ÷ 100) × Fuel Efficiency (L/100km) × Fuel Price ($/L). For example, a 500 km trip in a car consuming 8.0 L/100km at $2.00/L will require 40 litres of petrol and cost exactly $80.00.
How much CO2 does my road trip produce?
Burning one litre of petrol produces approximately 2.3 kg of CO2 (and 2.7 kg for diesel). A 500 km trip burning 40 litres produces 92 kg of CO2, requiring approximately 4 mature trees over an entire year to offset.
Are aviation fuel and Avgas calculated the same way?
No. Aviation fuel burn is calculated by multiplying flight duration by engine fuel flow (gallons or litres per hour) plus mandatory CASA 45-minute VFR reserves. For pilot flight planning, use our dedicated E6B Aviation Flight & Fuel Calculator.
