Online Marketplaces in Australia: How To Choose Where To Sell and Grow
An online marketplace is a platform where many sellers list products or services for buyers in one place, with the platform providing traffic, trust and often payments. In Australia, marketplaces range from local buy and sell platforms such as Facebook Marketplace to large retail marketplaces and specialist platforms for services.
Many businesses jump onto a marketplace because it is popular, then struggle with fees, competition and lack of customer data. This guide explains how marketplaces work, how to compare them and six steps to choose where to sell.
Quick Answer: Should Australian Businesses Sell on Marketplaces?
Australian businesses should sell on marketplaces when the platform already attracts their buyers and the fees still leave a profit. Marketplaces offer instant traffic and trust but limit customer data and brand control. Most businesses benefit from using marketplaces alongside their own website. Start by checking where your buyers already shop.

How Do Online Marketplaces Work?
Online marketplaces work by attracting buyers at scale and letting sellers pay for access through fees, commissions or advertising. The platform sets the rules, such as Facebook’s Commerce Policies, and controls how listings are ranked and shown.
| Factor | Marketplace | Your own website |
|---|---|---|
| Traffic | Built in | You must earn it through SEO and ads |
| Fees | Commissions or listing fees | Hosting and payment fees |
| Customer data | Limited | Fully yours |
| Brand control | Low | High |
| Rules | Set by the platform | Set by you, within the law |
6 Steps To Choose an Online Marketplace
These six steps help Australian businesses choose marketplaces that add profit, not just sales.
- Find where buyers shop. Search your products on major marketplaces and note who sells and at what price.
- Calculate fees. Include commissions, payment fees, shipping and advertising in your margins.
- Check the rules. Read seller policies and restricted product lists before listing.
- Assess competition. Count sellers and reviews in your category.
- Plan customer capture. Use packaging and follow-up, within platform rules, to build repeat customers.
- Test, then scale. Start with a few products and expand what proves profitable.
Why I Treat Marketplaces as Rented Land
I treat marketplaces as rented land: valuable for traffic, risky as your only channel. Over two decades in marketing, including ecommerce and retail brands, I have seen sellers lose much of their income overnight when a platform changed fees or rules.
The safest strategy pairs marketplaces with an owned website, email list and search visibility. My ecommerce SEO guide explains building that owned channel. Claims in listings must also be accurate; the ACCC says a business must be able to prove any claim it advertises.
