A green slip is a type of compulsory motor vehicle insurance, most commonly referring to Compulsory Third Party (CTP) insurance for vehicles in New South Wales (NSW), Australia.

What is a green slip?

In NSW, a green slip is an insurance policy that:

  • Covers people injured or killed in a motor vehicle accident involving your vehicle (e.g., other drivers, passengers, pedestrians).
  • Is legally required before you can register a vehicle (except trailers, which are covered by the towing vehicle’s policy).
  • Used to be issued on green paper, which is where the name “green slip” comes from, but is now handled electronically.

It does not cover damage to vehicles or property – for that you need separate comprehensive or third‑party property insurance.

What does a green slip cover?

A green slip (CTP insurance) generally helps pay for:

  • Medical treatment and rehabilitation for people injured in an accident.
  • Lost income if someone cannot work due to their injuries.
  • In some cases, longer‑term care costs or lump‑sum compensation, depending on the scheme and claim outcome.

It is focused on injuries and death , not car repairs.

When do you need a green slip?

You usually need a valid green slip when:

  1. Registering a vehicle in NSW – you must have an active green slip in place first.
  1. Renewing registration – the vehicle must continue to be covered at all times it’s registered and driven.

Trailers don’t need their own green slip because they’re covered by the towing vehicle’s policy.

Green slip vs pink slip vs blue slip (NSW)

In NSW, people often hear about three different “slips”:

  • Green slip – CTP insurance for injury and death cover; required for registration.
  • Pink slip – yearly eSafety inspection that checks whether older vehicles (over five years) are roadworthy.
  • Blue slip – inspection for unregistered vehicles or vehicles coming from interstate/overseas before they can be registered.

These are separate requirements that may apply at different times in a vehicle’s life.

Why is “what is a green slip” a trending topic?

The phrase “what is a green slip” regularly trends in Australia because:

  • New drivers and people moving to NSW encounter the term during registration and often confuse it with regular car insurance.
  • Recent explainers and guides from insurers and comparison sites (NRMA, AAMI, Youi, greenslips.com.au) highlight changes and reminders about registration and CTP rules.
  • Each year, price changes, policy tweaks, and government scheme updates send people back online searching for clear explanations.

Online forums and comment sections often include posts like:

“I’ve got comprehensive insurance – do I still need a green slip?”
“Moving to NSW, what is a green slip and how is it different from rego and pink slips?”

These reinforce the ongoing confusion and keep the topic active.

Mini example story

Imagine you’ve just bought a used car in Sydney.
You receive a registration renewal notice telling you:

  • You need a pink slip because your car is more than five years old, to prove it’s roadworthy.
  • You must buy a green slip from an insurer, so injuries in any crash involving your car are covered.

Only after the pink slip is done and the green slip is in place can you pay the registration fee and get the car legally on the road.
