Can you believe it's mid-October already? That somewhat startling fact means we're already halfway through spring. But never fear – there's still time to get out and about in Sydney, even if your wallet is looking a little bare.

Sort your car hire in Sydney and check out these four free things to do!

Head to the beach

This one's almost too obvious. It's getting hotter and you're looking for something free to do? Of course you'd go to the beach! Bondi is one of Australia's most iconic and has plenty to do apart from lying in the sun – surfing, swimming and coastal walks are but some of the things you could do.

Spring also brings a special (and free) event to Bondi – Sculpture by the Sea, the world's largest annual free outdoor sculpture exhibition. Beginning on October 19, a two-kilometre stretch of the coast will be transformed into a temporary sculpture park. It gets quite a bit of attention, too – it's expected that over half a million people will visit over the exhibition's 18 day running time.

Cycle through the city

While it might cost you a few clams to hire a bike, once you've done so, the only thing you'll have to pay for is the food to keep you going. Sydney caters fairly well to cyclists – there's a dedicated network of cycle paths that snake their way across the city.

If you have children and would prefer to stay off the roads entirely, there are several parks you can visit. Centennial Parklands is a collection of three smaller parks, covering a total of 360 hectares and filled with trees, wildlife, ponds and statues.

Hang out at Darling Harbour

There is perhaps no better place in Sydney to soak up the culture and the lifestyle than Darling Harbour. Found in the heart of the city, the place is always buzzing with people and is a great spot to just people-watch. If you want to spend a bit of coin, you can visit the SEA LIFE Sydney Aquarium, the WILD LIFE Sydney Zoo, or dine and drink at one of the many restaurants and bars.

There are, however, some attractions you can visit for free. The Australian National Maritime Museum can be found at the Northern end of Darling Harbour. While you'll need to shell out for the premium exhibits, much of the museum's standard fare is browsable for free.

Appreciate some art

Art & About was once a festival-style program that packed a single month of the year full of free art exhibitions. It's now transformed, however, into a continuous calendar, with different things starting and stopping all year round.

There's currently only one installation running – "The Last Resort" by Anri Sala, a rotunda on Observatory Hill, Watson road, transformed with drums on the ceiling that produce a contemporary interpretation of a Mozart concerto. Previous exhibitions include "Little Sydney Lives" featuring photographs from child photographers and "Australian Life", a gallery of 22 images that examine the country's identity.

You don't need to spend an arm and a leg, or even a few dollars, to keep yourself entertained in Sydney this spring. Don't delay it any longer; book your car hire in Sydney today!
