Best Places to Buy and Sell Online in Australia in 2026

The amount of money that Australians spent online is 82.6 billion in 2025, which is a 14 percent increase over the previous year. It is now more than ever that you can buy and sell online Australia whether it is clearing out the garage, finding a second hand car, or expanding a small business. However, with dozens of platforms available, selecting the right one will save you time, money, and much frustration. This list includes the best Australian buy and sell sites in 2026 — the free local classifieds to the nationwide retail marketplace — to help you select the best site to suit what you are specifically requiring.

The Reason Why Australians Are Increasingly Buying and Selling Online

One of the largest driving forces of more Australians going online is the cost of living. Buyers are in search of cheaper prices and vendors are converting unwanted stuff into additional income. As per the Australia Post eCommerce Report 2026, 8 out of 10 Australians are currently searching online ads site Australia for the best bargain before purchasing anything. Marketplace apps are used by 69% of shoppers — almost as often as retailer websites at 78%. And given the percentage of 41% of households in Australia shopping online at least once a fortnight, it is no longer a trend. It is a very ingrained habit.

Mobile is at the heart of it. Marketplace sessions in Australia are increasingly starting on a phone (between 77 percent and 85 percent of sessions): the most desirable platforms are those that can be used effectively on a phone: fast, simple and easy to navigate using a small screen.

The Difference Between Classifieds and Retail Marketplaces

To select a platform, it is convenient to know about the two broad categories of the platforms in Australia.

The local classifieds marketplace is one that pairs you to a local seller or buyer. Listings are usually free or extremely cheap, and the transaction occurs between individuals — usually cash on pickup or a mere bank transfer. They suit best second hand products, automobiles, furniture, employment, property and services. No platform fees are taking away your sale price and you are selling to the individual who is purchasing you.

The retail marketplaces such as eBay and Amazon Australia operate in a different manner. They are organized online stores featuring controlled checkout, shipping applications, and inbuilt buyer safeguards. They are effective in new goods and business inventory and products that are shipped across the country instead of collected locally. The trade-off is cost — platform fees usually cost 8–15 percent of each sale. To a privy seller clearing the unused room, these fees can quickly accumulate.

The Top Websites to Sell and Purchase on in Australia

Dealin — Free All-in-One Classifieds in Australia (Recommended)

The only local site that has offered the benefit of listing cars, furniture, jobs, property, services, and businesses in the same site, free of charge, is Dealin. It is designed to cater to ordinary Australians who wish to connect with consumers nationwide without incurring exorbitant listing charges. Dealin is used by individuals, tradies, car dealers, property owners as well as small businesses to list, promote and grow. Listings are live within minutes and all are under one dashboard. To the vast majority of Australians, Dealin is the best starting point.

• Most appropriate: all persons: casual sellers, frequent buyers and SMEs
• Costs: no fees (free)

Gumtree

Gumtree is still the largest purely classifieds site in Australia, and about 96 percent of its traffic is domestic. It possesses an established base of users of autos, furniture, jobs, and second-hand goods, and there are free listings with paid upgrades to get additional exposure. The audience is older and the platform is long enough to legitimately have local trust. But, over the past few years, numerous sellers have noted an increase in the number of scam messages and a slow selling period on it, so it is worth listing on Dealin with it.

Facebook Marketplace

Facebook Marketplace is currently one of the most active buy and sell platforms Australia of everyday household products. It is free, mobile-first and allows the buyer to view the Facebook profile of the seller to gain some social security. The cons are lots of lowball offers and time-wasters, and you even have to have a Facebook account to play. It is great to transport ordinary goods in a short time frame like furniture, infant equipment, clothes but not very well to expensive products or something that is business-related.

eBay Australia

When you need to find buyers all the way across the country and you need buyer protection in place that is well organized, then use eBay. Its seller rating system makes it the most reliable site when it comes to more expensive goods and the auction style can inflate final prices to higher levels than you would get with a classifieds listing. Their primary disadvantages are the charges, approximately 12 percent of the final sale price, and a listing procedure that is a much lengthier affair than placing an advertisement on a classifieds site. Best suited to electronics, collectibles and things that are worth the hassle of packing and posting.

• Best use: electronics, collectibles and high-value goods
• Fees: around 12% end value fee

Amazon Australia

Amazon Australia leads in new retail goods and is projected to take 20% of all internet sales in Australia buy and sell websites by 2026. To customers it provides extensive product choice and dependable delivery. It needs a professional account to sellers and is appropriate to businesses that have stable and recurring inventory and not single sales. It is not made to deal with second-hand items, local classifieds or personal deals.

Trading Post

Trading Post is among the oldest classifieds websites in Australia that have a faithful following of motors, farm equipment and rural products. The general traffic is not as high as that of Gumtree or Facebook Marketplace but serious, intent-driven buyers in the respective categories are attracted. Worth listing on with a primary platform when selling a vehicle, a trailer, or big machinery.

What Platform Would You Recommend?

The correct solution is all about what you are selling and to whom you want to communicate.

• When selling old furniture, appliances, or household goods, consider Dealin, Facebook Marketplace, or Gumtree first.
• Dealin Motors, Gumtree and Trading Post are most likely your best bets in case you are selling your car privately.
• Dealin Jobs is placed next to Seek and Indeed when it comes to finding or advertising a job.
• In the case of property, Dealin Property collaborates with realestate.com.au and Domain.
• In case you are a small business and sell products, it is worth combining Dealin Marketplace, eBay, and Amazon AU.
• And when you want to purchase or sell a business wholesomely, you go to Dealin Business For Sale and Seek Business.

To the majority of ordinary Australians, beginning with Dealin takes care of all the above in one free platform — without needing to use a variety of applications or having to pay a percentage of every transaction.

How to Be Safe When Purchasing and Selling Online

Online classifieds are safe provided you have a few basic steps to follow. Always pick up and drop off to local meetings and sellers at a busy place — a forecourt of a petrol station or car park in a shopping centre is good. Keep all your communication within the platform to have a clear record in case anything goes awry. Watch out on PayID scam requests whereby a purported buyer requests you to accept the transfer then collect the item once they have gathered the item — this is one of the most popular fraud methods on Australian classifieds sites at the moment. And when a price is too good to be true it is nearly always true.
