Brains,
The idea is to ensure;
a) The properties comply with safety standards.
b) The properties have adequate building & contents insurance (contents mean fittings - not renters own property)
c) The properties have adequate landlord insurance.
If accident occurs the $10 million public liability cover from the landlord insurance kicks in.
Now the idea of seperate entity is to pay what they deserve, not to pay what they can take.
If the courts feel they can get everything from you, then you will read in the papers the courts have awarded a record payout - not because its fair, but because they had the means to get it from you.
Why do courts award such payouts? - because they can, Ive heard (source forgotten) a court will award what it can to take the burden off the public and target the private.
And if your insurance company can find a way to make you pay instead of them, then great!
To recap - the idea is to ensure you insure adequately to cover your obligations to society.
