Australia's Housing Shortage: Why Supply Can't Keep Up (And What It Means for Property Prices)

The Core Problem: Supply and Demand Are Moving in Opposite Directions

At its most basic level, property prices are driven by supply and demand. Right now, those two forces are pulling in opposite directions, and the data backs it up.

According to the latest UDIA Housing Index (December quarter 2025):

• The housing index is 6% below the decade national average
• It sits 16% below the series peak recorded in June 2021
• Demand is up 2% quarter-on-quarter and 7.1% year-on-year
• Population growth is running at nearly 20% year-on-year
• Supply, however, is down 2.4% quarter-on-quarter

In plain terms: more people need homes, fewer homes are being built. That's a recipe for sustained price pressure.

Approvals Are Up, But Completions Tell a Different Story

At first glance, dwelling approvals look encouraging. In November, new home approvals jumped 15% compared to October, with higher-density approvals up 34%. Year-on-year, approvals are up 20%.

But here's the catch:

• Approvals ≠ completions. Every stage from approval to commencement to completion sees a decline in numbers.
• Dwelling commencements are actually down 5.5% quarter-on-quarter
• The current pace of approvals, around 16,000 per month, is approximately 20% below what's needed to hit Australia's 1.2 million homes target over five years
• No state is currently on track to meet its share of that target
• New South Wales is particularly behind, building only around two-thirds of the homes it needs

The approvals pipeline looks better on paper than it is in reality.

‍

It's Taking Longer Than Ever to Build

Even when homes are approved and construction begins, they're taking significantly longer to complete than historical averages:

• Units now take an average of 9.27 quarters (over 2 years) to complete, an all-time high
• The long-term average for units was 7.35 quarters
• Houses are averaging 3.46 quarters, up from a trend of 2.45
• Townhouses are experiencing similar blowouts

Why is it taking so long? 

A combination of factors:

• Rising land costs (Sydney land prices have risen from $96/sqm to over $2,460/sqm over 10 years)
• Higher construction costs that haven't come back down post-pandemic
• A wave of builder and construction company collapses reducing industry capacity
• Skilled labour shortages slowing project delivery

More approvals mean nothing if the industry can't physically build fast enough.

The Rate Hike Factor: What the RBA's Move Means for Renters and Investors

The RBA's recent rate hike, and signal that another pause of 3-6 months is likely, adds a further layer of complexity to the housing picture.

Here's how rising rates interact with the supply shortage:

• Fewer people can borrow, pushing more Australians into the rental market
• Rental vacancy rates are already critically low, with listings falling sharply
• If rate cuts don't materialise, rental prices are likely to rise significantly over the next 12-18 months
• The average new Australian mortgage has surged to nearly $750,000, with New South Wales averaging $873,000 and Queensland reaching $736,000

Despite rate rises, prices have continued to grow in many markets. During the 13 consecutive rate hikes from record lows, many Australian markets still recorded 30-40% price growth. Why? Because credit availability still drove buyer activity, and that demand had nowhere else to go.

‍

First Home Buyers Are Still Entering the Market

The federal government's expanded 5% deposit scheme has added further momentum:

• Nearly 32,000 first-time buyers took out a mortgage in the most recent quarter, the highest since early 2022 when the cash rate was 0.1%
• First home buyer loans increased by 9.1% in the past year
• As loan sizes grow and more buyers enter, upward price pressure continues

This isn't a sign of an overheated market about to collapse. It's a sign of a market with genuine structural demand that isn't being met by supply.

What Searches for New Homes Are Telling Us

Searches for new homes on realestate.com.au have surged to the highest levels since 2022. But this demand isn't simply flowing into new builds, because new builds aren't available in sufficient numbers, and when they are, they're priced significantly higher than established properties.

The result? That pent-up demand flows directly into the established property market, where supply is already tight and stock levels remain well below long-term averages.

For investors, this is important: established properties in high-demand locations remain a key beneficiary of new housing undersupply.

‍

What Does This Mean for Property Investors?

The data consistently points to one conclusion: Australia's housing shortage isn't a short-term blip. It's a structural, multi-year challenge driven by:

• Chronically low construction relative to population growth
• Rising build costs and builder insolvencies
• Long build timelines delaying supply
• Ongoing demand from migration, first home buyers, and upsizers

For investors, this environment creates a clear case for:

• Buying established properties in markets with strong demand fundamentals
• Acting sooner rather than later, as waiting for certainty often means paying higher prices
• Focusing on long-term hold strategies that benefit from sustained price pressure
• Avoiding oversupplied unit developments where high-density approvals are concentrated

The gap between supply and demand doesn't close quickly. And in property, that gap is priced in over time.
