Unfortunately Sammy, this is yet another scenario where the owner has to pay for a lawyer to get their strata committee to repair common property issues. It took me six years to have our dilapidated lift replaced, despite residents being stuck in the lift on a regular basis, some for half an hour.
Tina is right. Get copies of all emails regarding the matter. As I live in NSW, going to NCAT does not necessarily require lawyers. But you have to be well prepared and brave.
