The Problem with Australia's Property Market

Australia's property market is one of the most expensive in the world, with hundreds of billions in sales every year. However, if you've ever tried to buy or sell a home, you'll know how hard it can be to find one thing: the actual price, whether it be how much the house down the road recently sold for, or how much the house on the street over is guided at.

PropertyPrice.net product identity

Here's why:

  • Price guides (how much an agent estimates the property is worth) are often vague or selectively shared.
  • Sold prices can be hidden, delayed or locked behind paid reports.

As a result, buyers are left guessing and sellers face a less informed market.

This lack of transparency doesn't just frustrate people - it makes the whole system harder to trust.

How we increased price transparency

We first built propertyprice.net for a small property investment group, but quickly realised it solved a much bigger problem. Now open to the public, propertyprice.net allows users to discover both price guides for properties currently on the market and sold prices for recent sales.

The idea is simple: if the information exists, people should be able to see it. No waiting, no paywalls - just clear, accessible data to make more informed decisions.

For buyers, that means confidence when deciding which properties are likely to be within budget, and less time wasted on attending inspections, buying building and pest reports and having contracts reviewed.

For sellers, it means attracting serious, informed interest and having access to the latest data for the comparable sales.

For the market overall, this means more accountability and fairer outcomes. Transparency shouldn't be optional - it should be standard.
