If you have written evidence that you raised these issues more than to months ago, with no response, then you can apply to Fair Trading for mediation prior to taking a Section 232 (2) action against the owners corporation (as represented by the strata committee) for failure to fulfill its statutory duties.
If you’re not prepared to shake things up officially – and that may be all it will need – then you should probably just let it go. The power of inertia is huge and the number of excuses people will come up with for doing nothing is often a lesson in creativity and self-justification.
But as soon as you give people a reason for not doing nothing, you’ll be surprised at how much support you generate.
