When do I need to register for GST as a reseller in Australia?
Register for GST when your annual reselling turnover reaches $75,000. You must register within 21 days of hitting this threshold. Below $75K, registration is optional but can be useful to claim input tax credits on stock and business purchases. GST is 10% on all taxable sales.

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.
