19 simple ways to turn $100 into $200


Aussies looking to bring in a bit of extra cash to boost their primary income, or even save for something special, don’t need to go far.

One of the best and easiest ways to make money fast is to sell what you already have – or can acquire cheaply – while others can take on small jobs or opt for the slightly less reliable option of trading or gambling.

Here are 19 creative ways that anyone with a spare $100 and who is willing to work hard can easily double their money.

Volunteer for overtime

Most of us shrink away from overtime because of the extra hours but if you need money, let your supervisor know that you’re available to work.

Sell unwanted items on ebay

Start by selling things around the house that you no longer need, then with the money you raise, you can look for a niche – for example, some vendors hit rummage sales and thrift stores for cheap goods they can resell.

Return any old purchases or gifts

If you’ve received gifts you really don’t want – and they’re still in the packages – try returning them. Some retailers will take them back up to a year later.

It’s not going to make you rich fast, but it’s an easy way to raise money. Make sure you save any container which offers a 10c refund at collection depots and cash them in.

Also, picking up empty cans and bottles around the community means you are not only helping the environment and stopping pollution of our rivers, you will be making money as well.

Baby sitting

Baby sitters are always in high demand. A couple of five-hour gigs over a weekend could earn you $100 alone.

Become an Uber driver

Ride-sharing platforms like Uber let you turn your own car into a business at times that suit you, and without spending a dollar.

Set up a small cleaning business

Whether it’s window, car or home cleaning, a small business like this takes very little to set up and can quickly earn decent returns.


Tutors commonly charge up to $50 per hour, and although these websites take a healthy cut of that, they provide a no-cost way to start and quickly turn $100 into $200.

Odd jobs

Ask around if your neighbors need any odds jobs done and even if you need to buy materials to do it, you’ll quickly earn that money back, plus more.

Collect and sell scrap metal

Scrap metal recycling is another great way to make money. Turning scrap into cash is as easy as bringing in all metal objects you would normally throw away to our scrap metal centre and you will be paid cash based on the current scrap metal prices.

Sell your photos

Some websites, such as Shutterstock, allow you to post and sell your photos online for a fee.

Write product reviews

If you’re a tech junkie and buy a lot of new products, you may be able to do paid reviews on blogs. Blogs often have affiliate arrangements with tech products and will pay for user reviews.

Become a moving billboard

If you don’t mind having a large commercial sign on your car – or having it “wrapped” in ad material, you can earn a decent amount of money to boost your income.

Take surveys

Some companies will pay you for your opinions or allow you to earn points which can be redeemed for cash.


The odds aren’t guaranteed but it works for some people.

Buy shares

Buying the right shares at the right price is a popular way for Aussies to double their money.

Make lemonade

Make your own lemonade and sell it on a hot day or at an event – a high markup would double your money quickly.

Street performing

Whether you're a musician, magician, mime, juggler, clown, or comedian, if you can entertain people, you can make money busking.

Sign up for a rewards credit card

Some rewards credit cards give out a cash or point bonus redeemable on anything from flights to supermarket shopping.
