5 Best Car Auction in Sydney (2026)

Grays is one of Australia's best-known auction companies, and its Arndell Park site in Western Sydney is the local hub for its car sales. It runs online auto auctions across a huge, constantly changing catalogue, with weekday inspection and pickup at the yard. As the highest-volume name here, it's where a lot of Sydney buyers start, though the scale means the experience can vary from one lot to the next.

CarNet Auctions runs a Smithfield yard in Western Sydney that both auctions cars and operates as a used-car dealer, so you can buy off the lot or sell your own vehicle through them. Reviewers describe a low-pressure process and staff, Tony and Shane come up often, who follow up and handle the paperwork end to end. It keeps longer hours than the dealer-only houses, including Saturdays.

First State Auctions is a Sydney CBD auction house on York Street, and it's the odd one out on this list: its catalogues run to designer handbags, fine and second-hand jewellery, and collectible pieces, not cars. Bidding is online with a fresh catalogue each week, and reviewers rate the ease of the process and the quality of the items. It surfaces under Sydney auction searches, but if you're after a vehicle, it isn't the place.

Auto Auctions operates from Old Guildford near Granville in Western Sydney, buying and selling cars including electric vehicles, and it's set up well for interstate buyers who can't inspect in person. Reviewers describe video walk-arounds, clear communication, and staff, Matt and Seth among them, who manage everything from inspection to pickup. It also handles quick car sales for people offloading a vehicle.

Carlins Automotive Auctioneers has been running since 1960 and holds dealer-only vehicle auctions weekly across Sydney, Melbourne, Brisbane, and Perth, with its Sydney base at Girraween. Alongside the trade auctions, it buys cars and can source specific vehicles buyers are after, and it lists wholesale and retail stock online. The dealer-only format means it's aimed more at the trade than walk-in retail buyers.
