I wouldn't touch property in Australia, but that's probably just me.
These things to think about are if you own only one property, it's an economies of scale thing.
First off in NSW if it's not your PPOR you pay land tax, they abolished the cut off so you pay on any investment property.

You then get to pay rates, both council and interest.
Then you are expected to do maintenance, I know the place I rent the owner had to spend more on installing a working air con than he makes off me in 10 months. That's without them having to fix some other minor problems because I can live with those. This isn't even taking into account structural issues your property may develop, you see so many renovation shows because houses really are that shoddy
My place has cracks all over the place because of the soil type but it really doesn't bother me, when the sun comes shining through I might start worrying. And that is without termite or mold.
If you don't manage it yourself you pay a cut to the Real Estate agent to lease out. If you manage it yourself you might possibly earn more working at maccas than the fees you save.
On top of that you get to pay insurance, if your tenants destroy your house great you get a fraction of your money back, otherwise your insurance premiums just suck money from you. You also get to worry every day it's not rented out.
Houses aren't very liquid. I don't consider being able to get a HELOC as liquidity.
Most people who negatively gear hope to get capital appreciation when they sell so if they lose say $5k a year on it they hope when they sell it will go up by more than $5k a year on average. But just as things can go up they can also go down.
If you can find a cashflow positive place then great, but be aware it may not stay positive for long.
If you are really interested have a read of the somersoft forums, they are a great resource for Australian property investment. Just be aware the people there are heavily property focused so it may be a bit biased, but some have made a good living at it, but remember not everyone is as dedicated or lucky to find deals.

You really need to check where you are at in life and what your aims are for the money to be able to get a good picture of whether property is for you. If you only have $10k deposit and don't make more than $30k a year then maybe purchasing a property worth even 3 times your yearly pre-tax income ($90k) may not be a good idea. People say property is low risk, only if you have the funds to see you through the rough times. How many times have you read stories in the newspaper of families who are going broke because interest rates have risen and they need to pay $30 more a week for the house?
People do make money off property, some work hard on finding the good deals, some get lucky but overall I wouldn't put my money on the casual investor making more than if they were in stocks. I'm more into stock and alternative investment vehicles just so you know my bias
On the plus side, you have something you can draw more money against. You can depreciate some of it. You can write it off on tax. It could appreciate more than it costs you to run. You get to drive past it and think "That is mine".
Wrapping properties seems to be the big money thing at the moment, the rent to own deals.
Edit: Just to add, you also get to pay a nice chunk for the privilige of buying and selling the property to a variety of places like the real estate agent (commission), solicitors (contracts, conveyancy), the government (stamp duty, Vendors Tax) and so on.
