Having used postal address for many years, I have not had a problem with the registry.
Specialist residential tenancy lawyers in WA? I have never come across one. I have dealt with many para-legal workers, in various government-funded legal help services for tenants. In general I have found a lack of understanding for the reality of owning residential property. As the Magistrates Court is a no-cost jurisdiction, I have never personally come across a lawyer who works in residential tenancy court. I have personally represented owners in Kalgoorlie, Midland, Rockingham and Perth Magistrates Courts, and often met para-legals, but never lawyers.
You appear to be ignorant about violence committed by tenants. For example in Perth 4 weeks ago a property manager was bashed by a tenant at a final inspection - see

20 bad landlords over a year? Its possible, for sure. But compare that around 100 plus tenants every single week in WA taken to court for non-payment of rent, property damage etc.
Tenants hide their address from the landlord? They do that all the time. Its called leaving without a forwarding address. Commonest trick in the departing tenant's book.
I have made this original post not for legals but for Woodbridge and other owners who have concerns for their privacy and safety. Play it safe okay? When you have done a hostile eviction, and the tenant has threatened you and your family, you will rest a little easier if the tenant does not know where you live.
