Smart side hustles: ways to earn extra and invest towards your future
In 2025, the cost of living is higher than ever, and many Australians are looking for ways to supplement their income. Whether you’re a young professional working towards a home deposit, a parent balancing work and family, or just looking for ways to boost your financial security, a side hustle could be the answer. Not only can it help cover everyday expenses, but it can also provide an opportunity to grow your investments and build long-term financial stability.
With so many options out there, finding the right one can feel overwhelming. The good news? There’s something for everyone—whether you want to work online, in the gig economy, or build passive income over time. Here are some of the best side hustles that can actually work.
Online side hustles
Paid surveys
Completing online surveys is a simple way to earn extra cash or rewards in your spare time. Many survey platforms offer small payments in exchange for sharing opinions on brands and products. With Raiz Surveys, Raiz users can earn Raiz Rewards, which go directly into their Raiz account—helping to grow savings and investments effortlessly.
Freelancing (writing, graphic design, marketing, etc.)
If you have skills in writing, design, social media, or even admin work, freelancing platforms like Upwork, Fiverr, and Freelancer make it easy to connect with clients. Many freelancers start with small projects and build their way up over time.
Selling digital products
Creating and selling digital products—like templates, e-books, or stock photos—can generate ongoing income with minimal maintenance. Platforms like Etsy and Gumroad allow you to sell to a global audience.
Online tutoring
If you have expertise in a subject, online tutoring is a great way to earn extra income. Websites like TutorMe and Superprof connect tutors with students in everything from maths and science to music and language skills.
Gig economy side hustles
Rideshare & food delivery
Driving for Uber, DiDi, DoorDash, or Menulog is a flexible way to earn extra cash. While fuel and vehicle costs should be factored in, the ability to work when it suits you is a big plus.
Pet sitting & dog walking
Platforms like Mad Paws and Pawshake make it easy to offer pet sitting, dog walking, or even boarding services. Perfect for animal lovers who want to get paid for spending time with pets.
Task-based work (odd jobs & handyman services)
Sites like Airtasker connect people who need odd jobs done with those willing to do them. This can include anything from furniture assembly to garden work.
Passive income side hustles
Renting out a spare room or property
If you have extra space, renting it out on Airbnb can be a great way to generate additional income (remember to get the OK from your landlord first if you’re renting!). Even renting out a car with services like Uber Carshare can bring in extra cash.
Investing in the markets
While investing isn’t a traditional “side hustle”, it can be a way to potentially grow wealth over time. By reinvesting dividends, you may be able to build a steady income stream. However, investing always carries market risks, and returns are not guaranteed.
Content creation (YouTube, blogging, or podcasting)
If you enjoy sharing your knowledge or creativity, content creation can turn into a profitable side hustle. Monetisation comes from ads, sponsorships, and affiliate marketing, but it takes time to grow an audience.
Making the most of your extra income
A side hustle can be a great way to increase financial security, pay off debt, or invest towards future goals. Whether you’re freelancing, driving, or creating content, setting aside some of your extra earnings can help build long-term wealth. Many people choose to invest a portion of their side hustle income to make their money work harder for them and create a more secure financial foundation.
No matter which side hustle you choose, the key is finding something that fits your lifestyle and goals. With the right approach, a little extra effort today could lead to greater financial freedom in the future.
