Lots of things.
1. Negative gearing is a huge culprit, we have incredibly favourable tax policies for people investing in real estate and neither major party is willing to touch something so dear to the bloody baby boomer generation.
Basically as I understand it, you can negatively gear a property ad infinitum, and use the losses in rental income versus mortgate size to offset other tax liabilities.
2. There's also a first home owner grant where first-time buyers get given up to $15,000 to help buy the first home they purchase. Helps bait people into joining the overinflated market.
3. Some of it's due simply to economic growth - we haven't had a recession since 1991 and have gotten a lot richer in that time. That's gonna have a flow-on in real house price terms even without 1 and 2 channeling people's investment money into real estate.
4. Lack of density due to maybe some cultural factors. Australians are weirdos and a lot of us hate apartments and dense living because we're stupid and think kids need back yards to play cricket in rather than parks with other kids. This means more push for larger blocks of land and larger houses which pushes prices up. Density is increasing even as they sprawl outwards, but Australian cities are all still pretty sprawly. Sydney is our densest populated city and Greater Sydney is roughly as dense as LA, just 40% that of London. Canberra is as low density as friggin Phoenix.
There's some pretty great charts/maps of our major cities population distributions here
5. Supply issues, again related to density. There's not enough dense housing in the inner cities and probably not enough housing stock for weirdos who like the suburbs either.
Part of this is political economy. Planning and development is mostly a state government domain but due to the vertical fiscal imbalance (due to different high court constitional law decisions, states can't raise income tax but are mostly responsible for healthcare and education) those State governments are heavily dependent on transaction tax (stamp duty) revenue. So they're not terribly interested in reducing the cost of housing as it impacts their own income - they've skin in the house price game.
Planning and development is also a mess of conflicting local and state government agencies anyway. There's little coordination in policies for managing urban growth, for example in public transport to support more dense development. A lot of the choicest inner city areas are pretty NIMBYish with small local councils and long-term residents. Etc etc. In most cities except Sydney it's more expensive to build and buy inner city apartments than a big house on the fringes.
6. Then there's just some geographical constraints that operate in tandem with low densities and a rich population that's gone 23 years without recession... for example most of the urban fringes and potential infill places are owned in small blocks by existing semi-rural or hobby-farm residents, making it hard to do big new developments. Sydney as I understand it has basically hit the limits of available land to expand into, having reached mountains, ocean, and national parks in pretty much every direction. Making infill the only possibility.
7. Politically, the people impacted by lack of affordability aren't important voters. With single member electoral districts renters are a minority in most places, and outer-suburban electoral districts have generally been the marginal seats, ones which have swung elections. Any attempt to change most of the policies that are feeding the situation are going to be electoral poison with the middle class, baby boomer, mortgage-holding homeowner demographic which swings election.
The federal government, for instance, is so disinterested they scrapped the body tasked with merely monitoring housing supply.
So basically I'd be looking mostly to negative gearing and economic prosperiy as a culprit for the inflation while noting density is also a factor keeping underlying pries high.

Negative gearing is where the income from rent from the property is less than the costs of the investment, which includes the interest of the investment loan and other expenses.
Loss-making investors are hoping to be able to eventually sell the property for a price that more than makes up for the losses incurred along the way.
Australia is one of the few countries among those with similar tax systems to allow negative-gearing losses on all income-producing assets, not just property, to be offset against investors' other income.
It is seen as particularly generous to investors, given the capital gains on which capital gains tax applies is discounted by 50 per cent as long as the investment is held for at least a year
