Our Three-Week Australian Bucket List

Three-Week Australia Itinerary – Cairns to Melbourne

Day 1 – 3: Cairns, Far North Queensland

• Two nights in Cairns
• Travel to Airlie Beach & spend the night

Day 1 - Scuba Diving

Explore the Great Barrier Reef like never before with a scuba diving day tour! Whether you’re an avid snorkeller, keen to learn to dive or just want to unwind on a boat amongst World Heritage reef ecosystems, this is the best way to see the reef in Australia! Find Nemo and swim with turtles; totally a bucket list Aussie experience!

Day 2 - Cape Tribulation & the Daintree

Head to Cape Tribulation through the mesmerizingly lush Daintree Rainforest. This slice of biodiverse wonder is the world’s oldest rainforest, with an abundance of tropical flora and fauna. There are awesome guided tours that take care of all the details like transport and food if that’s how you prefer to discover the Daintree and Cape Trib!

Day 3 - Travel to & settle in Airlie Beach 

The drive from Cairns to Airlie is about 8 hours, so buckle up, chuck on the tunes and get road-tripping! Check-in late to your Airlie accommodation.

Day 4 – 8: The Whitsundays, Queensland

• 5 nights in Airlie Beach, Whitsundays
• Travel to Rainbow Beach & spend the night

Day 4 - Airlie Beach exploring

The bustling little township of Airlie is laden with markets, boutiques, swimming spots and excellent dining, so explore and relax into island time!

Day 5, 6 & 7 - Sail the Whitsunday Islands

As the gateway to the Whitsunday Islands, a trip to Airlie Beach isn’t complete without an overnight sailing experience. With an array of lively backpacker adventures to more upmarket trips, there is something for everyone! Explore the famous Whitehaven Beach, swim with fish, snorkel the reefs and sail in style, making friends, eating delicious food and chasing sunsets along the way!

Day 8 - Travel from Airlie Beach to Rainbow Beach 

The trip from Airlie Beach to Rainbow Beach is about a 10-hour drive, so sit back and enjoy the scenery! Spend the night at a Rainbow Beach hostel, waking up to the sound of the ocean.

Day 9 – 12: K'gari (Fraser Island), Queensland

• Two nights on K’gari (Fraser Island) tour
• One night in Rainbow Beach
• Travel to Noosa & spend the night

Day 9, 10 & 11 - K’gari 4WD Safari 

Catch the barge from the mainland to discover the boundless beauty of K’gari (Fraser Island). From gem-coloured lakes to infinite rolling coastlines and dense forests to freshwater creeks, this island is laden with incredible wonders, as well as interesting Indigenous history. The best way to 4WD down the beach and spot dingoes on K’gari is on a tour, of which we recommend a three-day, two-night camping trip to really immerse yourself in the island’s magic!

Day 12 - Travel from K’gari to Noosa

This leg is only about an hour and a half drive, so sit back, relax and roll up to your digs in Noosa feeling zen. From here we recommend a drink on Hastings Street, and of course, a barefoot walk on Main Beach!

Day 13 & 14: Noosa

• One night in Noosa, Sunshine Coast
• Travel to the Gold Coast & spend the night 

Day 13 - Noosa surfing, kayaking or free exploring 

Noosa is a divine holiday destination, home to radiant beaches, great surf, cruisy vibes and unique hidden gems. A total favourite choice amongst backpackers, we recommend grabbing a surf lesson, which includes your board hire, and hitting the waves! After this, a dinner with mates and a night at the popular Koala Bar is bound to have you feeling like a local. Just don’t forget the sunscreen!

Alternative activities include a Noosa Everglade kayak or a free day hiking the Noosa National Park and working on your tan!

Day 14 - Travel from Noosa to Gold Coast

About 2 hours by car, jump from one beach paradise to the next, arriving at the Gold Coast at your own pace. If you’re keen for a big night, hit the Surfers Paradise main strip, where the music’s always turned up and the night’s always alive! 

Day 15 & 16 - Gold Coast, Queensland

• One night on the Gold Coast
• Travel to Byron Bay & spend the night 

Day 15 - Gold Coast

Browse the shops in Surfers Paradise, unwind on Miami Beach, pick a coastal walk, hire a surfboard or enjoy a beach BBQ in the park. There are heaps of local free activities in the Gold Coast, so catch up on some downtime in this backpacker destination where beach and city meet!

Day 16 - Travel to Byron Bay

A super short leg today, with the trip to Byron Bay only taking an hour. 

Day 17 & 18: Byron Bay, New South Wales

• One night in Byron Bay
• Travel to Sydney & spend the night

Day 17 - Byron Bay

The famous bohemian beachside town of Byron Bay is a must on your Australian road trip. Byron’s a pretty interesting town, and while much more developed, trendy and expensive than it used to be (as locals often lament), the vibes here are still really fun and the beaches are gorgeous. Head out for an avo on toast, hike up to the lighthouse and paddle out on a dolphin kayak tour for a day of sunshine!

Day 18 - Travel from Byron to Sydney 

Head south on your second-last leg of the journey towards the iconic city of Sydney. From Byron Bay, the trip is about 8 hours.

Day 19 & 20: Sydney, New South Wales

• One night in Sydney
• Travel to Melbourne & stay the night

Day 19 - Sydney, New South Wales 

Be welcomed by the impressive arches of the Opera House as you explore Sydney! With unmissable photo destinations like the Sydney Harbour Bridge, Circular Quay and Luna Park, using the old yellow ferries is by far the funnest way to view the Harbour. A stop at the local fish market before a coastal stroll to Bondi Beach is the best way to get a feel for all aspects of the city! Come hungry for the sights and leave with a camera roll full of happy snaps!

Day 20 - Travel from Sydney to Melbourne 

Your ultimate destination is just around the corner, so hit the road for one last time and arrive in Melbourne in 9 hours.

Day 21: Melbourne, Victoria

•  One night in Melbourne +

Day 21 - Melbourne City 

Woohoo, you’ve made it to the grungy coffee capital of Australia! Melbourne is laden with colourful street art, a bustling arts scene and, as aforementioned, fantastic coffee.

How much does three weeks in Australia cost?

Ah yes, it’s budgeting time already. The first questions you’ll have when planning your trip to Australia is “how much will it cost?” and “how much daily spending money do I need” for your three-week road trip? 

The average itinerary for 3 weeks in Australia is anywhere between $2400 and $4000, including tours, accommodation and transport. Pre-booked itineraries are the best way for budget backpackers to get more bang for their buck with huge discounts, as well as enjoy seamless travel with everything prepaid and preplanned!

How much spending money do I need for three weeks in Australia?

As for daily spending money, it really does depend on how fancy you want to travel. If you’re more of a budget backpacker and are okay with eating budget food and sending postcards rather than spending heaps on souvenirs, $80 - $100 per day is fine. That’s about $1800 of spending money for 3 weeks (when you add accommodation, transport and tours).

If sit-down dining and ample shopping allowances sounds like you, we recommend about $150 - $300 per day, on top of an itinerary (about $3500 of spending money all up, not including accommodation, transport and tours).
