Australia’s property markets have always been shaped by a mix of supply, demand, and sentiment. But in 2026 a new layer of pressure that is less visible, but increasingly influential, has emerged. The sharp rise in fuel costs and the broader cost of living squeeze is shaping the rental markets and shifting the expectations of both landlords and tenants.
The rising cost of construction as well as the impact to household budgets and tenant mobility, the rising fuel prices are quietly reshaping rental dynamics. For landlords, the implications are nuanced, whilst there is potential for rental growth there are also heightened risks around tenant affordability, vacancy, and long-term portfolio stability so it is increasing important that landlords understand how to respond strategically in this changing environment.
The Impact of Fuel Prices on Investment Properties.
We are all aware that fuel cost does not just affect what you pay at the bowser. It flows through almost every part of the economy because when fuel prices rise, so too do transportation, construction, maintenance, and goods costs. Recent global disruptions have pushed oil prices higher, feeding directly into inflation across Australia. But the price of fuel also indirectly impacts the property markets.
For property investors, this manifests in several ways:
• Higher maintenance costs: Tradespeople face increased travel and materials expenses, which are passed on.
• Rising construction costs: New housing supply becomes more expensive, slowing development. Reduced supply of properties will push property prices higher.
• Increased strata and property management costs: Energy and transport-heavy services rise in price.
• Tenant’s cost of living pressures: This impacts the affordability of the rental market, and can impact cashflow, profitability, and vacant periods for Landlords.
At the same time, households’ budgets are feeling the squeeze. Rising petrol prices, alongside interest rates and general inflation, are stripping billions from Australian household budgets each month. This dual pressure—higher costs for landlords and reduced capacity for tenants—creates a delicate balancing act on affordability.

Rental Prices
Despite cost pressures on tenants, rents across Australia continue to climb. In early 2026, national rents rose more than 5% annually, with some cities like Sydney seeing increases above 7%. The primary driver is not fuel directly, but supply constraints. Vacancy rates are sitting around 1–1.6%, well below long-term averages, and rental listings remain significantly reduced.
At the same time, we are seeing:
• Population growth continues to outpace new housing supply.
• Construction pipelines are slowing due to rising costs.
• Investor borrowing capacity is impacted by interest rate increases.
Fuel prices amplify these issues by increasing development costs and slowing supply further, indirectly pushing rents higher. However, there is a ceiling on what tenants can pay, they can only pay what they can afford, and this leaves Landlords restricted on their rental increases, and at risk of having vacant periods if their property’s rent is priced too high. The largest risk is that the constraints on the amount of rental income a landlord can charge may turn a previously positively geared, cash flow positive property into a negatively geared property that is costing the landlord each month to cover the mortgage costs.
The Affordability Ceiling
One of the most important dynamics in today’s rental market is the growing gap between rents and wages. Australian tenants are now spending around 33% of their pre-tax income on rent, the highest level on record and over the past five years, rents have increased roughly 2.5 times faster than wages.
This creates what investors should recognise as a natural limit to rental growth.
When cost of living pressures intensify:
• Tenants downsize or relocate.
• Share housing becomes more common.
• Some tenants exit the rental market altogether.
In practical terms, this means that while landlords may face rising costs, the market does not always allow those costs to be fully passed on.
Rent Increase Rules
Across NSW, VIC and QLD, recent reforms have aligned the core rule that rent can generally only be increased once every 12 months (however, the way this rule operates and the additional protections around it, vary by state).
The rent increase rules must be a critical consideration for Landlords in a volatile economic environment. Even if costs rise quickly due to fuel or inflation, landlords cannot adjust rents immediately or frequently. Strategic timing and forward planning are essential.
The Tenant Risk: When Rent Becomes Unsustainable
As cost-of-living pressures mount, tenants may reach a tipping point. With rising expenses across fuel, groceries, energy and transport, households are being forced to reassess their budgets. Some estimates suggest weekly living costs have increased significantly across multiple categories, including transport driven by fuel volatility.
For landlords, this introduces a key risk that tenants may leave not by choice, but by necessity.
This can result in:
• Increased tenant turnover
• Shorter lease durations
• Greater competition for affordable rentals
• Higher arrears risk in extreme cases
While demand remains strong overall, not all properties are equally protected. Higher-end rentals or properties in less accessible locations may feel this pressure more acutely.
The Cost of Vacancy, A Growing Concern
A vacant property is one of the most underestimated risks in a landlord’s portfolio, particularly in a rising cost environment. If a property sits empty, landlords still face:
• Mortgage repayments
• Council rates
• Insurance
• Maintenance
• Property management fees (in some cases)
At the same time, these holding costs are increasing due to inflation and fuel-related cost pressures. Even in a tight rental market, vacancy risk can arise if rent is set above what the market can bear, the property is poorly presented or located, or the tenants leave during seasonal slow periods.
In a high-cost environment, the strategy of pushing rent to the absolute maximum can backfire. A slightly lower rent with a stable, long-term tenant often produces better financial outcomes than chasing peak rent and risking vacancy.
Supporting Tenants Through the Squeeze
In a challenging economic environment, landlords who take a proactive and empathetic approach often see better outcomes. Supporting tenants is not just a moral consideration, it is also a sound investment strategy.
Some practical ways landlords can assist include:
1. Open Communication
Encouraging tenants to communicate early if they are struggling to afford rent, can prevent issues from escalating and discussions can be had early on.
2. Flexible Payment Arrangements
Short-term adjustments, such as payment plans, can help tenants stay in place during temporary hardship.
3. Moderate Rent Increases
Rather than pushing for maximum market rent, consider sustainable increases that tenants can realistically afford.
4. Longer Lease Options
Providing lease security can reduce turnover and give tenants confidence in uncertain times.
5. Property Improvements That Reduce Costs
Simple upgrades such as energy-efficient appliances or insulation can lower tenants’ living expenses and improve retention.
A Balanced Approach for Investors
The current environment presents both opportunity and risk.
The opportunities are that:
• Rental demand remains strong.
• Supply constraints support rental growth.
• Yields may improve in some markets.
On the other hand, risks lie when:
• Tenants are under increasing financial pressure.
• Rent increases are legally constrained.
• Vacancy risk can quickly erode returns.
The path forward for landlords is not simply about increasing rent to cover rising costs. It requires a more nuanced approach that balances financial performance with tenant sustainability. Those who understand the broader economic picture, including the ripple effects of fuel prices and inflation, will be better positioned to navigate this cycle.
In the end, successful property investing has always been about more than numbers. In today’s economic environment, it is equally about judgement, timing, and the ability to adapt to the current challenges.
