One week in Australia: a Sydney to the reef itinerary
Australia is enormous, and a single week cannot begin to cover it. What one week can do, and do brilliantly, is pair the country's most famous city with its most famous natural wonder. This itinerary runs from Sydney up to the Great Barrier Reef, mixing harbour city life, a day in the mountains, and tropical north Queensland, with a short domestic flight linking the two halves.
It is designed for first-time visitors who want the signature highlights without a punishing pace. You can follow it in either direction, and it adapts easily for couples, families, and solo travellers.

Countries covered: Australia. Suggested duration: 7 days. Best paired with the dry season in the tropical north, broadly June to October.
Day 1: Sydney
Ease into the trip around Sydney's vast natural harbour. Walk from the Sydney Opera House along the water to the Royal Botanic Garden, then across to Circular Quay for your first proper look at the Harbour Bridge. Spend the afternoon in The Rocks, the city's oldest quarter, and finish with dinner overlooking the harbour. Base yourself in a central hotel or a mid-range stay near Circular Quay so the main sights are on foot.
Day 2: Sydney beaches
Give the day to Sydney's coast. Ride out to Bondi Beach, then walk the clifftop Bondi to Coogee coastal path, which strings together a run of beaches, rock pools, and lookouts over the Tasman Sea. In the afternoon, take a ferry to Manly for a different angle on the harbour and a relaxed beach town feel. The ferry ride itself is one of the best value harbour cruises going.
Day 3: Sydney culture and harbour
Slow the pace with a morning at the Art Gallery of New South Wales or a wander through the Darling Harbour precinct. If you have the energy, a BridgeClimb or a simpler walk across the Harbour Bridge pylon lookout rewards you with a sweeping view. Keep the evening free to pack, as tomorrow is an early start into the mountains.
Day 4: Blue Mountains
Take a day trip west to the Greater Blue Mountains Area, a rugged expanse of sandstone plateaus, deep gorges, and eucalypt forest named for the blue haze cast by the gum trees. Ride to the classic lookouts over the Three Sisters at Katoomba, walk a section of forest trail, and breathe the cooler mountain air. Trains and organised day tours both run from Sydney, with the journey taking roughly two hours each way. Return to Sydney for the night.
Day 5: Fly to Cairns
Take a morning domestic flight from Sydney to Cairns in far north Queensland, a journey of around three hours. Cairns is the main gateway to the Great Barrier Reef and the Daintree Rainforest, and the change in climate is immediate as you step into the tropics. Settle in, walk the Cairns Esplanade and its lagoon, and book your reef trip for the following day. A mid-range hotel or a hostel near the Esplanade puts you close to the marina.
Day 6: The Great Barrier Reef
Give the whole day to the reef. Boats leave Cairns marina in the morning for the outer reef, roughly one to two hours out, where you snorkel or dive over coral gardens alive with reef fish, turtles, and rays. Choose a certified, reef-safe operator, and if you are less confident in the water, pick a trip with a reef pontoon. Our Great Barrier Reef visiting guide covers how to choose an operator and when to go.
Day 7: Daintree Rainforest
Spend your final day in the Daintree Rainforest, one of the oldest rainforests on Earth, an hour or two north of Cairns. Cruise the Daintree River in search of wildlife, walk a boardwalk through ancient forest, and reach Cape Tribulation, where the rainforest meets the reef. Return to Cairns in the evening for your onward flight. If your schedule allows a stopover, the town of Port Douglas makes a scenic stop on the way back.
Visa and entry
This is a single-country trip, so you need one entry authorisation for Australia. Most visitors travel on the Electronic Travel Authority or the eVisitor visa, both arranged online before departure and both allowing stays of up to 90 days. There is no visa on arrival. Our Australia entry requirements guide explains which route applies to your passport, and you can check the rule for your nationality on the Australia entry page.
Staying connected in Australia
Australia is vast, and mobile coverage thins out quickly once you leave the coastal cities. Sorting out data before you fly means you can pull up maps, ferry times, and reef tour bookings from the moment you land, without hunting for airport WiFi or a physical SIM.
An eSIM is the simplest option for most travellers. It installs digitally, so there is no card to swap, and you can set it up before departure. Saily offers Australia data plans that activate when you arrive, keeping your home number available for calls and messages.

Frequently asked questions
Is one week enough for Australia?
One week is not enough to see the whole country, but it is plenty to pair Sydney with the Great Barrier Reef, which is exactly what this itinerary does. Trying to add the Red Centre or the west coast in the same week would leave you spending most of your time in transit.
Should I do Sydney or Cairns first?
Either works. Starting in Sydney lets you ease in with a big city before the tropical north, while starting in Cairns front-loads the reef in case weather forces a reschedule. This itinerary runs Sydney first, then flies north.
How do I get from Sydney to Cairns?
A domestic flight is the practical option, taking around three hours. Driving the east coast is a wonderful trip in its own right, but it needs far more than a week to do well.
What is the best time of year for this itinerary?
The dry season in the tropical north, broadly June to October, gives the best reef conditions, with clearer skies and good visibility. Sydney is pleasant across much of the year, so plan the dates around the reef.
Do I need a visa for this trip?
You need authorisation to enter Australia, usually the Electronic Travel Authority or the eVisitor visa, arranged online before you fly. See our Australia entry requirements guide for the route that applies to your passport.
Is this itinerary suitable for families?
Yes. Sydney's beaches and ferries, the Blue Mountains lookouts, and reef pontoon trips all work well for families. Choose reef operators that cater to children and non-swimmers, and build in rest time given the travel between regions.
How much of this can I do by public transport?
Sydney is well served by trains, buses, and ferries, and the Blue Mountains are reachable by train. In the tropical north you will rely more on organised tours or a hire car, particularly for the Daintree.
Can I add the Uluru or the Red Centre in a week?
It is possible but rushed, as it means another long flight and at least a full day each way. Most travellers save Uluru for a separate trip or extend to ten days or more to include it comfortably.
How do I stay connected while travelling around Australia?
Coverage is strong in the cities but patchy in remote areas and at sea. Setting up a data plan such as a Saily eSIM before you arrive means you land connected, with maps, transport times, and tour bookings ready to go.
