Say G’ Day to these G Adventures Australia tours 🇦🇺

1. Best of Australia

If you have a limited amount of time and you’re willing to travel to Australia’s East Coast, hop on board this 14-day trip down Australia’s east coast and make the most of the time you do have.

With a solid mix of must-do experiences and unique adventures, you’ll enjoy a surfing lesson in Byron Bay, a sailing excursion in the Whitsundays, and a trek through Mossman Gorge in the Daintree Rainforest.

You’ll then have a few days in Sydney before heading out to other sights like the Blue Mountains and the Tasman Sea.

2. South Australia & The East Coast

Your trip begins in Adelaide, the capital of South Australia, where we meet the city’s famed churches and gardens.

After that you’ll head to the Grampians National Park, where you can take a hike through the lush forests while searching for wildlife. Head north to the Great Ocean Road, where you’ll enjoy the sights, sounds, and even taste of Victoria’s lush landscape.

Make your way to the Mornington Peninsula for a stay at the Mornington Peninsula Yacht Club and a swim in the warm waters of the Southern Ocean.

Next, make your way to the Whitsundays where we stop at the islands, snorkel, and swim with fish. From there the tour travels south to explore the Great Barrier Reef and visit Cape Tribulation, where you can learn to surf.

On the journey home you’ll head to Sydney, the largest city in Australia.

3. South Australia, Melbourne & the Great Ocean Road

Sometimes, you just don’t have time to see everything that Australia has to offer.

But don’t worry, fellow adventurer, because this 10-day tour will take you on a jaunt from Adelaide to Melbourne, with a mix of must-see highlights and unique experiences along the way.

From the bustling city to the laidback lifestyle, from the buzzing nightlife to the natural beauty, there’s a lot to do, and a lot to experience on this amazing trip!

4. Discover Australia

This is the journey to Australia’s most stunning destinations. First stop on this National Geographic Journey is Melbourne.

Here, you’ll explore the city’s unique and quirky dining scene. Next stop – Uluru-Kata Tjuta National Park.

You will then cruise around the massive rock formations that lie in the centre of the park. And after that, head to Sydney to explore this vibrant city.

Finally, your G Adventures Australia tour arrives in the north of Queensland to see how locals live in the tropics.

5. Most of the Coast: Sydney to Cairns

This Australia East Coast tour takes you off the beaten path and gives you a chance to see the country through a different lens.

From Sydney to Cairns, you’ll learn about everything from surfing to sailing, while traveling in small groups and getting a taste of what life is like on the land.

6. Brisbane to Cairns Experience: Sand Dunes & the Whitsundays

Kick-off your tour down under at a rooftop bar in Brisbane and prepare yourself for exploring the stunning wilderness of the Noosa Everglades.

Go 4x4ing on Fraser Island – the world’s largest sand island and the only known place where rainforest grows on sand.

Then head to the marina and embark on a private yacht which will be your home for the next two nights. Then to top it all off, you’ll set sail to a secluded cove in the Whitsundays which will be your floating home for the next two nights.
