public liability

My unit does not have body corp, and my property manager says I need public liability for the shared driveway. The Landlord insurance companies I talked to do not have such a policy. Is this something that you need to buy separately from a different company? Thanks

I am in NSW. As a first home owner, we've almost decided to purchase a 2-bedroom unit. The unit is currently leased by a tenant. My conveyancer suggested to get a public liability if we decide to keep them there. What sort of public liability insurance is it and how much does it normally...
