What should I do if my property use is being challenged by local authorities?

Consult a lawyer for advice. If you wish to challenge the local authority’s decision, you can apply to VCAT, but you must have valid grounds. This includes having standing (being adversely affected), a legal issue (justiciable), and ensuring VCAT has jurisdiction. The success of your challenge often depends on the remedy you seek, so defining this with your lawyer will help determine the best approach.
