Tenants from hell what a nightmare. I know it sounds complicated but the Residential Tenancy Act 1987 might be your best friend as it can provide a number of options to you.
The Magistrates Court has exclusive jurisdiction to hear residential tenancy disputes. The Magistrates Court is a relatively low cost, informal court. Tenants and owners represent themselves.
Did you want the lease between you and the tenant brought to an end? If so there are some simple measures you can put in place and certain forms you can serve on the tenant if they are in breach of their lease. The ultimate goal here is eviction
Its difficult to say what you can exactly do without knowing the problems the tenant is causing you and what they are doing that is really pissing you off but from the sounds of it this tenant is one that you want out of your life.
I hope you have some luck in dealing with the tenant and can send them to hell
