Apply to VCAT
You can apply to VCAT and ask them to make an order that the rent increase is not allowed.
If you have received the rent assessment report from Consumer Affairs Victoria (CAV), you must apply to VCAT within 30 days. If you do not apply to VCAT within 30 days, you will need to explain the delay to VCAT and VCAT will decide whether to allow your application.
If you choose to apply to VCAT without the CAV report, you will need to explain to VCAT why you should be allowed to apply without the CAV report.
You can apply to VCAT via their website.
