So property offers a much safer way to leverage your investment.
...really? That's not really how I see it.
On property returns:
The property market generally moves as a whole and you generally have an agent telling the vendor what their house is worth. Therefore, it's very, very hard to find a 'bargain'.
In the stock market, even though you have financial advisors (lol), you don't have anyone who really knows every stock. So if you dig through enough mud and dirt, you'll eventually uncover something worthwhile.
If you do this well enough, you'll absolutely smash any property returns (unless you start building/renovating).
On leverage:
Debt is debt, the bank can theoretically call in their loan when they feel there is no longer sufficient equity. They just don't do it with property because it'll trigger a domino effect.
Not to mention that a loan on a house takes up a considerable amount of your disposable income, locking you into that particular investment for a while.
And finally, Sirosisofliver (Not 100% on the spelling) and a few others wrote a thread on investment basics and some examples of PPOR vs IP. It's one of the greatest pieces I've seen on the pros/cons of each, so I'd definitely read that if I were you.
