1. High-Interest Savings Accounts and Term Deposits
In the current interest rate environment, high-interest savings accounts and term deposits are genuinely delivering passive income. Accounts from banks like UBank, ING, and Macquarie Bank have offered bonus rates of 5%+. On $10,000, a 5% savings account earns $500 per year — completely passively, risk-free, and protected by the Australian Government Guarantee up to $250,000 per institution.
2. Micro-Investing with Raiz or Spaceship
Apps like Raiz and Spaceship Voyager have made investing accessible with as little as $5. These platforms automatically invest your spare change or small regular contributions into diversified portfolios. Raiz offers portfolios ranging from conservative bonds to aggressive global equities. Spaceship specialises in tech-heavy global share portfolios.
3. Creating and Selling Digital Products
Digital products cost almost nothing to create and can be sold infinitely. Popular digital product formats include eBooks, Canva templates, Lightroom presets, Excel spreadsheets and planners, online course modules, and printable planners. Platforms like Etsy, Gumroad, Teachable, and your own Shopify store allow you to set up a digital product business with minimal upfront cost.
4. ETF Investing with Automatic Contributions
Setting up automatic monthly contributions to a low-cost ETF portfolio is one of the simplest passive income strategies. Choose a diversified ETF like VAS (Vanguard Australian Shares Index), VGS (Vanguard International Shares), or a combination. Set up an automatic transfer on payday and let it work. With $200 per month invested at a 9% average annual return, you'd have over $160,000 after 20 years.
5. Renting Out Assets You Already Own
A spare car can be rented out through platforms like Uber Carshare. A parking space in a high-demand area can earn $150–$400+ per month through Spacer or Parkhound. A caravan or campervan can earn $80–$200 per night on Camplify or Outdoorsy. Camera equipment, tools, sports gear, and even designer handbags can be rented through specialist platforms or Facebook Marketplace groups.
6. Affiliate Marketing and Niche Websites
Affiliate marketing involves recommending products and services and earning a commission when people buy through your link. Building a niche website, YouTube channel, or Instagram account around a specific topic and monetising it with affiliate links can generate genuinely passive income once the content is established and attracting organic traffic. The startup cost is low — a domain and hosting might cost $100–$200 per year.
