Keeping of the pet should have conditions set when the committee approved it. I doubt midnight leaking on the balcony would be agreed so it’s likely a by-law breach. In Qld you send a form 1 to your committee outlining what you feel is the breach, and they then have 2 weeks to get it addressed if it is – if they don’t proceed to adjudication. If it not finalized it risks being a fined offense if it gets to a Magistrates court. You might suggest ways forward but you don’t really care so long as the issue is resolved to your satisfaction. If not: rinse and repeat. but allow this to be the committee’s problem to solve, not yours.
