Transportation Costs in Australia if Brent Oil Hits $60: Impact on Low-Income Households

Brent crude oil at $60 per barrel would usher in a new reality for Australian households, particularly those with constrained budgets. For low-income families earning less than AUD 2,500 per month (equivalent to roughly €1,500), the ripple effects through the transportation sector could significantly strain household finances, impacting essential services and daily commutes.

Transmission Mechanism: From $60 Crude to Your Fuel Tank

When Brent crude trades at $60/barrel, this price directly influences the wholesale price of refined petroleum products like petrol and diesel in Australia. While crude oil isn't directly pumped into vehicles, its price dictates the cost for refineries. This cost, alongside refining margins, freight, taxes (including the fuel excise duty, currently AUD 0.488 per litre for petrol and diesel), and retailer mark-ups, determines the bowser price. At $60/barrel for Brent, modelling suggests an average unleaded petrol price in major Australian cities could stabilise around AUD 1.70 - AUD 1.80 per litre. For comparison, petrol prices in early 2024 were fluctuating around AUD 1.90 - AUD 2.10 per litre, indicating a potential moderate decrease but still a significant cost for low-income earners.

Australian Specifics: Geographic Spread and Public Transport Access

Australia's vast geography and relatively low population density outside major urban centres mean a higher reliance on private vehicle ownership for many, especially in regional areas. Public transport infrastructure, while robust in capital cities like Sydney and Melbourne, is less comprehensive in many suburban and rural areas. This forces a significant portion of low-income households, who often reside further from employment hubs due to housing affordability, to depend on private vehicles for work, school, and essential services. A 2023 Australian Household Income and Labour Dynamics study showed that transport costs already consume an average of 14% of disposable income for the lowest quintile of households. Even with petrol at AUD 1.75/litre, this percentage would remain substantial.

Concrete Example: Monthly Cost for a Low-Income Household

Consider a low-income household in outer Sydney, with two working adults, each driving 250 km per week for work and essential errands. This equates to approximately 2,000 km per month. Assuming an average vehicle fuel efficiency of 9 litres per 100 km, this household consumes about 180 litres of petrol monthly. At an average price of AUD 1.75 per litre (based on $60/barrel Brent), their monthly fuel expenditure would be AUD 315.

For a household earning AUD 2,500 per month, this AUD 315 represents 12.6% of their gross income, potentially leaving them with AUD 2,185 for all other expenses including rent, food, utilities, and healthcare. This does not account for other vehicle running costs like insurance, registration, and maintenance, which further erode their budget. This outlay could lead to trade-offs, such as reducing grocery spending or delaying essential medical appointments.

What Low-Income Households Can Do

To mitigate the impact of $60/barrel Brent and the associated transport costs:

1. Optimise Driving Habits: Gentle acceleration, steady highway speeds, and proper tyre inflation can improve fuel efficiency by 10-15%. This could save the example household AUD 30-47 monthly.

2. Explore Public Transport Subsidies: Investigate state-specific low-income public transport concessions (e.g., NSW's Gold Senior/Pensioner Opal card, although its reach is limited). Even partial shifts to public transport for some journeys can reduce fuel dependency.

3. Vehicle Maintenance: Regularly serviced vehicles are more fuel-efficient. Consider a lower-cost, older, more fuel-efficient vehicle if an upgrade is possible and financially viable.

4. Carpooling & Active Transport: Organise carpools for work or school with neighbours and colleagues. For shorter distances, walking or cycling can eliminate fuel costs entirely and offer health benefits. Local councils often provide information on cycling routes and walking paths.

Even at $60/barrel, fuel costs remain a significant budgetary item for Australian low-income households. Proactive measures and careful planning can help soften the financial blow.
