Hi,
Heaps of information here on Somersoft on that topic. Just do a search. I've got a couple of threads going where the experts here have helped me with all my questions on the topic around my Mona Vale townhouse development. There's a fair body of knowledge encapsulated in them alone. I owe a lot to SS for giving me all that fantastic advice...
Search "Mona" and you should find them.
Cheers,
Michael.
