What does the OC Act (in NSW) say?
In Victoria it states:
129 Care of lots
A lot owner must—
(a) properly maintain in a state of good and serviceable repair any part of the lot that affects the outward appearance of the lot or the use or enjoyment of other lots or the common property; and
(b) maintain any service that serves that lot exclusively.
So it’s not the case in Victoria. And I’ve just replaced 4 of those transformers that have gone faulty at my own expense.
OT: Newer replacement transformers are small, electronic and very cheap. And probably run cool – it’s the downlights that get hot.
