Second-Hand School Uniforms in Sydney: Where to Buy & Sell (2026 Guide)

TL;DR

• Sydney families spend $300 to $600 per child a year on uniforms, and buying second-hand cuts that by 60 to 70%
• You can buy and sell pre-loved Sydney uniforms online, at school second-hand shops, through parent Facebook groups, or at local exchanges like the Pymble Uniform Exchange
• Rethread lists every Sydney and NSW school in one place, with no listing fees and no commission
• Searching by your exact school is the fastest way to find the right blazer, kilt or sports kit in the right size

Sydney has some of the most expensive school uniforms in the country. A full winter set at a private or selective school can run past $500, and that's before PE gear, a blazer and the second pair of everything kids inevitably need. The good news is that Sydney also has one of Australia's most active second-hand uniform markets, if you know where to look.

This guide covers where to buy and sell second-hand school uniforms across Sydney and NSW, from the big-name exchanges to your own school's P&C shop, and how to find exactly what your child needs without trawling every parent group in the city.

Where to buy in Sydney

Online marketplaces

The fastest way to find a specific Sydney school's uniform is online, where you can search by school, size and condition instead of hoping a shop happens to stock it.

Rethread is Australia's dedicated second-hand school uniform marketplace, and every NSW school is already listed, from Sydney's selective and public high schools to the big independent and Catholic colleges across the North Shore, Inner West, Eastern Suburbs, Hills and beyond. You search your school, see what's listed, and buy direct from another Sydney family. Listing and browsing are both free. See everything available across the state on the NSW second-hand uniforms page.

Facebook Marketplace and school-specific parent groups are also popular in Sydney, particularly at schools with active P&C communities. The trade-off is no standard sizing or condition grading, and pickup and payment are left entirely to you.

Gumtree carries some listings too, but uniforms sit mixed in with general clothing, so searching by a specific Sydney school is hit and miss.

Uniform exchanges

Sydney is home to one of Australia's longest-running second-hand uniform services: the Uniform Exchange in Pymble, on the Upper North Shore. You can drop off items to sell on consignment or browse in person, which suits families nearby. The limitation is that it's one physical location. If you're in the Inner West, South West or Sutherland Shire, it's a hike, and stock depends on what's been dropped off for your particular school. For a specific school outside the North Shore, searching online first usually saves the trip.

Your school's own shop

Most Sydney schools run their own second-hand shop, usually staffed by P&C or P&F volunteers. These are the first place to check for your exact uniform because the stock is all for your school. They're typically:

• Open only a few times a term, often at the start of a term
• Cash or EFTPOS only, no online browsing
• Stocked solely from what other families have donated, so there's no guarantee your size is in
• Priced low, but with no returns or condition guarantees

Check your school's website or P&C Facebook page for opening days. Sydney shops sell out fast in the January and late-July back-to-school rush, so go early.

Op shops and fetes

Vinnies, Salvos and local op shops occasionally stock generic items like plain white shirts, grey trousers or sports shorts, though school-specific pieces with crests are rare. Sydney school fetes and spring fairs often run a second-hand uniform stall, which is great for a cheap bulk grab, but stock and sizing are pot luck.

Finding sellers near you

If you're searching "second-hand school uniform near me" from a Sydney suburb, the most reliable results come from filtering by your actual school rather than your postcode. A blazer from your child's school is the same whether the seller is in Parramatta or Penrith, and most Sydney families are happy to post, or meet for pickup. On Rethread, searching your school name surfaces every listing for it statewide, which beats hoping a seller lives in your exact suburb.

What should you pay?

Pricing varies by condition, item and school, but as a general guide:

Sydney's selective and private schools sit at the top of these ranges, which is exactly why buying second-hand saves the most there. As a buyer, anything above half the retail price is steep for used. As a seller, overpricing is the number one reason items sit unsold, so check what similar listings are going for before you set yours.

How to sell yours

Once your child has outgrown their uniform, selling it recovers some of the cost and gets it to another local family rather than the back of a wardrobe.

What sells fast

• Blazers and formal jackets, which are expensive new, so buyers actively hunt them second-hand
• Complete sets, which move faster than single pieces
• Sports and PE kit in good condition
• Anything with the school crest clearly visible, because Sydney parents search by school

Listing on Rethread

1. Go to rethread.com.au/sell
2. Search for your school
3. Add clear photos, the size, honest condition and your price
4. Listing is free and Rethread takes no commission when it sells

Most items sell within a few weeks when priced right, and listings go fastest in the January and late-July back-to-school windows.

Why bother with second-hand?

Beyond the savings, every reused uniform is one less that ends up in landfill. Australians send enormous volumes of wearable clothing to tip each year, and school uniforms, worn for a season or two and built to last, are among the easiest wins. Buying pre-loved in Sydney keeps good uniforms in circulation, supports other families, and quietly teaches kids that second-hand is normal and smart.
