Do I pay income tax on money made from reselling in Australia?
If the ATO considers your reselling a business, net profit is included in your taxable income and taxed at your marginal rate. If it's a hobby, sales are generally not taxable — but you also can't claim deductions. Personal item sales (things you bought for your own use and are now selling) are generally CGT events, not income — though the personal use asset exemption often covers items under $10,000. Speak to an accountant if your annual resale income exceeds $5,000.

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.
