Do Australian Consumer Law guarantees apply to secondhand sales?
ACL guarantees apply to traders (businesses), not private sellers. As a business reseller, buyers have rights to goods that match the description, are of acceptable quality, and are fit for purpose. 'Sold as is' disclaimers don't override ACL. However, ACL quality expectations are reduced for secondhand goods — a used jacket doesn't need to perform like new. Full disclosure of known faults protects you. Private sellers (genuine personal items, one-off sales) are not bound by ACL guarantees but must still not make false representations.

Key things to know for Australian sellers
Australian online selling has its own quirks: GST registration thresholds, Australia Post rate structures, and platform-specific buyer behaviour differ from the US and UK advice you'll find most readily online. Checking ATO guidance directly and using the Australia Post postage calculator for accurate quotes are good starting points.
Using multiple platforms together
Most successful Australian resellers end up selling across at least two platforms. The marginal effort to list on a second platform is much lower if you already have photos and a description, and reaching two different buyer pools meaningfully increases your chances of a sale.
