I would be reluctant to say property will continue to appreciate at the same rate as it has historically, ie average double in value every 8-10 years. How ever I would I do think it will continue to appreciate and don't see how property falling more than 10% at any point, a 10% fall would see buyers flooding back into the market.
With that the Aussie dream of owning you own home is still relevant and will continue to be so, you own home is more than just an asset so you can't compare it to owning stocks.
As for investment property, historically the returns are less that stocks but it carries less risk. I doubt that will change
