20 Best Side Hustles in Australia For Extra Income

18. Reselling and Flipping

Buy items cheaply from garage sales, op shops, or clearance sales, then resell them online for profit. Success comes from understanding market values and spotting underpriced items.

Many resellers focus on categories they’re passionate about – vintage clothing, collectibles, electronics, or furniture. This makes the research process more enjoyable while building genuine expertise.

The hunt becomes addictive for many resellers. Finding a $5 item that sells for $50 provides both financial reward and the thrill of the discovery.

What you can earn: $300-$1,500+ per month

Time you’ll spend: 10-30 hours per week

How to start: Begin with categories you know well. Use eBay sold listings to understand current market values. Reinvest profits into better inventory.

Insider tip: Resellers who build relationships with specific op shops or garage sale organisers often get first access to the best items.
