“The economic fallout from the Middle East will not be evenly distributed across the global economy,” notes Ray White Group chief economist Nerida Conisbee.

For Australia, the impact tends to land in a very uneven way, creating both tailwinds and headwinds that ultimately flow through to households, borrowers, and the property market.

Australia’s “two-speed” exposure to energy shocks

On one side, Australia stands to benefit from higher global oil and gas prices. As a major exporter of LNG and coal, tighter global energy markets can lift national income. This typically flows through to stronger export earnings, higher company tax receipts, and increased royalties, particularly in resource-heavy states such as Western Australia and Queensland.

On the other side, Australia is heavily exposed as an energy importer in everyday life. That means global oil price spikes are quickly felt at the bowser, with petrol and diesel costs rising for households and businesses alike.

For borrowers, especially first-home buyers and property investors, this translates into a quieter but very real pressure point: higher living costs reduce discretionary income and can tighten borrowing capacity at the same time as lending conditions remain strict.

Fuel costs ripple through construction and inflation

While fuel prices are most visible at the petrol station, their impact spreads much further across the economy. Transport and freight costs rise, which flows into grocery prices and general household goods. Aviation costs increase, lifting airfares. At the same time, fuel-intensive industries face higher operating expenses.

Outer suburban and regional households are often the most exposed, as they rely more heavily on private vehicles and longer commuting distances.

In property and construction, the effect is structural. Energy is embedded across the entire building process, from diesel-powered machinery on site to the transport of materials and the production of inputs like steel, cement, and bricks.

As a result, higher fuel prices increase the cost of delivering new housing stock. At the same time, persistent inflation linked to energy makes it harder for interest rates to fall meaningfully, which keeps mortgage affordability under pressure.

For developers, this environment can tighten feasibility. Projects that rely on debt or thin margins, particularly higher-density developments—may no longer “stack up,” slowing the pipeline of new supply just as population growth continues.

A tightening supply story meets elevated demand

“The result is a complicated picture for the housing market,” Conisbee explains.

On one hand, higher interest rates and rising living costs are expected to temper price growth. On the other, weaker new construction continues to reinforce Australia’s underlying housing shortage.

Recent data from PropTrack shows national home values are still around 9% higher than a year ago, with more affordable capitals and lower-priced segments driving much of the growth.

This imbalance between supply and demand tends to shift pressure into the rental market. Even when price growth slows, limited new supply keeps rents elevated.

According to REA Group estimates, rental affordability remains under strain: a median-income household earning around $124,000 can now afford just 37% of advertised rentals nationally, while households on closer to $75,000 can access only around 2%.

What this means for borrowers and the mortgage market

For many Australians, the key issue is not just property prices or interest rates in isolation, but the combination of rising living costs, constrained supply, and tighter lending conditions.

For medical professionals and high-income borrowers, these dynamics still present opportunities in the property market, but they also highlight the importance of structured lending strategies, careful cashflow planning, and understanding serviceability under different economic scenarios.



At Medico Loan, we continue to see how external economic shocks, whether energy-driven or inflation-led, flow directly into borrowing power, property timing decisions, and long-term wealth planning.

In uncertain conditions, the focus shifts from simply securing finance to structuring it in a way that remains resilient across changing cycles.
