Should you take on a second job or side hustle in 2025?

With living costs continuing to climb across Australia, more professionals are turning to second jobs and side hustles as a way to make ends meet. But while the extra income can offer some financial relief, it’s not a decision to make lightly.

New research from Robert Walters shows that 70% of Australian workers are open to taking on additional work. For some, this might mean freelance consulting in the evenings. For others, it could be weekend work in retail or hospitality. But before jumping in, it’s important to weigh the benefits against the risks and understand your employer’s policy around second jobs.

In this article, we explore what’s behind the rise in side hustles, the pros and cons of pursuing one, and what you should consider before saying “yes” to a second job.

Why are more Australians working multiple jobs?

The growing interest in side hustles isn’t surprising when you look at the numbers. According to the Australian Bureau of Statistics, almost one million Australians are now working multiple jobs. Among 20–24-year-olds, almost 1 in 10 are juggling more than one role.

At the core of this trend is financial pressure. Despite a national wage increase of 3.2% over the past year, inflation and rising essentials, from rent and fuel to groceries, have outpaced earnings growth in many regions.

A closer look at the data:

• 90% of Australians say they’re concerned their current income won’t cover expenses this year (Robert Walters research, 2025)
• In NSW, 90% of workers say their salary doesn't match the cost of living
• In VIC and QLD, that figure is 84% and 83% respectively
• WA fared slightly better, with 27% of workers saying their salary has kept up with inflation

As Shay Peters, CEO of Robert Walters ANZ, notes:

“Work-life balance used to be the top priority, but today, salary has retaken centre stage.”

Pros of taking on a second job or side hustle

Taking on a second income stream can offer some meaningful benefits, particularly in uncertain economic times.

1. Extra income
   The most obvious benefit is financial. A second job or side hustle can help cover rising expenses, reduce debt, or support long-term savings goals like buying a home or investing.
   
   
2. Skill development
   Side gigs can be a great opportunity to build new capabilities, especially if they involve a different industry or discipline. This can also help future-proof your career.
   
   
3. Career pivot potential
   Some professionals use a side hustle to test a career change before fully committing. For example, a lawyer might freelance as a copywriter or take a short course in UX design while working part time.
   
   
4. Greater autonomy
   Freelancing, consulting or launching a small business on the side can offer a sense of independence and flexibility that traditional nine-to-five roles may not.

Risks and challenges to consider

While second jobs can be financially helpful, they can also create new complications.

1. Burnout and time strain
   Juggling multiple roles can lead to long hours, less downtime, and eventual burnout, especially if you’re already in a demanding role.
   
   
2. Employer policies
   Some employers have clear policies around secondary employment or conflict of interest. In certain industries such as legal, financial services, or government, second jobs may not be allowed or may require disclosure.
   
   
3. Tax and compliance
   Earning additional income can impact your tax bracket or require you to register for an ABN (Australian Business Number), especially if freelancing. It’s worth getting professional financial advice before you start.
   
   
4. Focus and performance
   If a side hustle begins to affect your performance in your main role, it could put your primary employment at risk.

What to consider before starting a side hustle or second job

Before jumping into another role, it’s important to ask yourself a few key questions:

• Is your employer okay with it? Check your employment contract or HR policy before starting anything external.
• Do you have the time and energy? Realistically assess your current workload and personal responsibilities.
• What are your financial goals? Clarify whether the extra income is short-term support or part of a long-term plan.
• Will it impact your wellbeing? Be honest about how it may affect your mental and physical health.
• Is it sustainable? Make sure any second job won’t compromise your performance in your primary role.

Final thoughts

With the cost of living showing no signs of slowing down, many Australians are rethinking how they earn and spend their income. Side hustles and second jobs are becoming part of the new reality for professionals who need more financial flexibility.

But whether you're considering an after-hours job, a passion project, or freelance work, it’s important to weigh the benefits carefully against the personal and professional risks. Make sure you understand your obligations, your employer’s stance, and your own capacity.
