is a roadworthy certificate the same as a pink slip

Short answer: no — they’re cousins, not twins.

In NSW, a Pink Slip is an eSafety inspection mainly for registration renewal; a Roadworthy Certificate (RWC) in places like VIC and QLD is generally for sale/transfer or clearing a defect and can cover a broader checklist.

• Pink Slip (NSW): usually annual when required and lodged electronically with Service NSW; separate Blue Slip if the car’s unregistered or has major changes.
• RWC (VIC/QLD): typically one-off for transfer; issued by licensed testers and the exact items vary by state.

Neither is a full mechanical report — they’re safety compliance checks so you’re legal, not pampered. Expect roughly AUD 50–200 depending on state and vehicle, and check your local authority for the fine print.
