State-by-State Towing Rules in Australia: Quick Reference Guide

Heading interstate with your caravan? Don’t assume the rules are the same everywhere. While Australia has national definitions for towing weights and limits, each state and territory has its own quirks when it comes to licences, speed limits, mirrors, brakes, and enforcement. This quick guide gives you the essentials so you’re not caught out at the border.

Tip: Always check the official transport authority website before you travel. Rules can and do change, and penalties vary by state.

National Rules That Apply Everywhere

  • You must not exceed any of your vehicle or caravan’s limits (ATM, GTM, GVM, GCM, tow ball load).
  • All caravans over 750 kg GTM must have brakes. Over 2,000 kg ATM generally requires electric brakes and breakaway systems.
  • Towing mirrors are required if your caravan obstructs your view behind.
  • No passengers are allowed in a moving caravan.

  • Print or save your compliance plate numbers and weighbridge receipts.
  • Carry your caravan registration papers — required in some states.
  • Fit quality towing mirrors before leaving; don’t risk a fine mid-trip.
  • When in doubt, slow down. 90–100 km/h is the sweet spot for safe towing nationwide.
