If you are a tenant, your landlord or rental agent is legally obliged to provide a copy of up-to-date by-laws.
If you are a landlord or owner-resident the by-laws should have been attached to your title deeds or documents of sale. If you no longer have them your solicitor or conveyancer may have hem. Also your strata manager should have them too.
Some schemes also include the consolidated by-laws in their AGM agendas.
