In fact in QLD the BC has a duty to enforce the bylaws it cannot just ignore the request because if it dosn’t take action the complainant can take action against the BC to force it to take action against breaches of bylaws.
This is from a ruling from an Adjudicator ruling in QLD:
In lieu I order that the body corporate take such positive and reasonable steps as it thinks appropriate to ensure that By-law 16 and By-law 22 of the scheme are known to, and complied with, by all owners and occupiers of the scheme.
Must admit I’m not sure what would happen if the BC ignored the ruling.
