Last year, Sydney Airport staff successfully returned more than 7,000 items to passengers. However, some passengers aren't so lucky. We're not sure how you could leave your Hublot Big Bang Unico White Ceramic (ref. 421.HX.1170.RX) watch on a plane, but someone's managed to do it.
The good news is that it—and plenty of other high value items—are now up for auction in the annual Sydney Airport Lost Property Auction, which is hosted by Theodore Bruce Auctioneers & Valuers and is now live at the auction website. Every year the auction raises money for charity, and this year the auction house has partnered with Sydney's Inner West Council so all proceeds go to support local families struggling with cost-of-living pressures by providing swimming lessons for children.
With nearly $2 million raised for charities since the annual auction started 12 years ago, the high value items we've chosen below will go a long way towards teaching kids to swim. To start things off, Sydney Airport has donated $100,000, and the airport wants to raise a further $200,000 from the auction. Let's check it out!

Here's each auction category at the Sydney Airport Lost Property Auction 2025:
There are five auction categories to browse through in the Sydney Airport Lost Property Auction with everything from cameras to laptops, watches, jewellery, sneakers, jackets, sunglasses, and even whisky (our favourite) up for grabs. We've sifted through the most desirable, high-dollar items from the auction in each of these categories and featured them below.
The most valuable item in the entire auction is the Hublot Big Bang Unico White Ceramic (ref. 421.HX.1170.RX), which is priced at AUD$34,300 when new. While it's not in great condition and its authenticity cannot be verified by us through a computer screen, if it is infact real, it's a high-valuable piece, with prices sitting in the $20-30,000 range on the seconday market. The 44 mm watch uses a HUB1280 UNICO Manufacture Self-winding Chronograph Flyback Movement with Column Wheel and Matte Black Skeleton Dial (72 hours power reserve). This movement is housed in a microblasted and polished white ceramic case with six H-shaped titanium screws. It's not for the feint of heart, but it's a serious watch nonetheless.

While prices can change, these are the next most expensive items up for grabs at the auction:
The Tamron 35 – 150mm E Mount lense is fine, but it's not one of the best lenses on the market. If you're a fashionable person then you'll probably get excited about Lot 3287, which is described as a a men's Red Puffer Vest, Marked Ralph Lauren Polo. We can't authenticate the year, but an original vintage 1993 Polo HI TECH Utility Vest like this would fetch around USD$550 in todays money.
Of course, the Louis Vuitton duffel bag and bottle of Hennessy X.X.O Cognac will fetch decent money when their auctions end.
When you're not looking at the high-end of the market, the auctions are a great way to donate proceeds to charity and score some discounted tech. Plenty of Apple and Samsung products are up for grabs, including AirPods and tablets. Check out all of the items at the website, linked below!
