How to Claim the Sixt Auto Club Discount
- Confirm you’re a current member of NRMA, RACV, RACQ, RAA, RACT, RAC WA or AANT, whichever operates in your state.
- Head to Sixt’s Auto Club partner page or your own Auto Club’s member benefits page (e.g. mynrma.com.au for NRMA members) and book through the dedicated Auto Club link, not the general Sixt homepage.
- Have your membership number ready, you’ll need to quote it at the time of booking and again when you collect the vehicle.
- Confirm the discount has been correctly applied to your quote before completing payment, 20% off passenger vehicles or 15% off commercial vehicles, base rate only.
- Bring your Auto Club membership card or digital membership confirmation with you to the counter when collecting the vehicle.
How Much Can You Save with Sixt?
| Discount Type | Saving | Applies To |
|---|---|---|
| Auto Club member discount (passenger vehicles) | 20% off base rate | NRMA, RACV, RACQ, RAA, RACT, RAC WA, AANT members |
| Auto Club member discount (commercial vehicles) | 15% off base rate, plus up to 200km free per day | Utes, vans, 4WDs, buses, moving trucks |
| International rentals for Auto Club members | Up to 15% off | Sixt locations outside Australia |
| Booking in advance vs on the day | Genuinely cheaper, consistently | All vehicle types |
Discount applies to the base rental rate (time and kilometre) only, not additional fees or damage waiver products. Confirmed directly from Sixt’s own Auto Club partner page and multiple state motoring club benefit pages, always check your specific Auto Club’s current terms since rates can change.
Best Ways to Save with Sixt
- Join an Auto Club if you’re not already a member. The 20% passenger vehicle discount alone is worth more than most short-term promo codes, and it applies year-round, not just during a sale period.
- Book a commercial vehicle if you need extra space. The 15% commercial discount plus 200km free per day makes utes, vans and moving trucks genuinely good value for interstate moves or larger group trips.
- Consider an EV if one’s available at your location. Sixt was the first rental company in Australia to offer EVs, and rentals include unlimited free charging in the daily rate, a real saving if you’re doing significant kilometres.
- Check for a suburban branch, not just the airport. Sixt operates a genuinely dense branch network beyond airport counters, a suburban pickup can sometimes be cheaper and easier than fighting airport queues.
- Book ahead if your dates are flexible. Advance booking consistently beats last-minute rates, and avoiding peak periods (Christmas, Easter, school holidays) brings the price down further.
What Is Sixt?
Sixt is a global car and truck rental company with over 100 years of history, expanding into Australia with over 30 years of local operations. It now runs more than 145 locations across every Australian state and territory, including all major capital city airports (Sydney, Melbourne, Brisbane, Perth, Adelaide, Canberra, Hobart, Darwin) and a genuinely broad network of suburban branches beyond the airport.
Sixt’s Australian fleet spans passenger cars and SUVs through to a full commercial range, utes, vans, 8-seaters, 4WDs, buses and moving trucks. It was the first car rental company in Australia to offer electric vehicles, and continues to run one of the largest EV rental fleets in the country. Sixt is also the confirmed, official car and truck rental partner of Australia’s major Auto Clubs, a genuinely differentiated partnership most competitors don’t have.
Is Sixt Worth It?
Yes, particularly if you’re a member of an Australian Auto Club, the 20% passenger vehicle discount is a genuine, consistent saving that beats most short-term promo codes most competitors offer. Sixt’s broader vehicle range (utes, vans, trucks, EVs) and denser branch network beyond airports are real differentiators worth knowing about even if you’re not chasing the Auto Club discount specifically.
Why Your Sixt Code Might Not Work
- You booked through the general Sixt site instead of the Auto Club partner link. The 20%/15% Auto Club discount only applies when booking through the dedicated Auto Club portal or partner page, not a standard Sixt booking.
- Your membership number wasn’t quoted at both booking and collection. Some locations require the membership number to be confirmed again when you pick up the vehicle, not just at the time of booking.
- The discount doesn’t apply to fees or damage waiver products. If your total doesn’t look 20% lower, check whether you’re comparing the base rate specifically, not the full quoted price including extras.
- A third-party coupon code has expired or was never genuine. Given how inconsistent third-party coupon sites are for Sixt specifically, treat any code found outside Sixt’s own site or your Auto Club’s member portal with caution.
Final Thoughts: Best Sixt Deals Right Now
For most Australians, the real Sixt deal worth chasing isn’t a promo code, it’s the confirmed 20% Auto Club member discount available through NRMA, RACV, RACQ, RAA, RACT, RAC WA or AANT. Combine that with booking in advance and considering a suburban branch over the airport counter, and Sixt becomes a genuinely competitive option across cars, utes, vans and moving trucks alike.
