The landscape is known for its dynamic birdlife, and consists of tidal mudflats, billabongs and enormous sandstone escarpments.

You can get up close and personal with all sorts of marine life - whether snorkelling, diving or on a boating excursion. Most famous for whale sharks, The Ningaloo Coast is UNESCO protected.

5. Great Ocean Road and the Twelve Apostles, Victoria

Why it’s special

One of the world's most scenic coastal drives and a highlight of holidays in Victoria, the 243 km road links the coastal towns between Torquay and Warrnambool. Only eight of the Twelve Apostles, the limestone pillars that rise from the ocean near the coastal town of Port Campbell, now remain. Their striking presence gives an insight into this part of the road which is also known as the Shipwreck Coast.

Best time to visit: The Great Ocean Road can be driven at any time of the year. In winter you’ll see more grey skies and dramatic storms and in summer it is likely to be more picturesque but often includes bumper-to-bumper holiday traffic. The best time for the drive is during autumn (March to May) and spring (September to November).

Ideal trip length:  3 - 4 days

How to experience it: Drive from Melbourne, stopping for beach days in coastal towns and venturing inland for rainforest walks and wildlife experiences. Book in advance and start at the RACV Resort in Torquay, then caravan parks or private accommodation along the way.

What to know before booking: This iconic coastal drive is on the Australian National Heritage list. Some of the turns are very tight and it’s easy to get distracted by the gorgeous coastal views and lush forests. Use your mapping apps and a travel agent to help you plan stops along the journey.

The Twelve Apostles are about 230km from Melbourne. Driving straight via the inland highway takes three hours, but it can take up to five hours if you take the scenic coastal route. It’s possible to do the trip in one day but it's better if you take your time.

6. Cradle Mountain-Lake St Clair National Park, Tasmania

Why it’s special

Home to Tasmania's highest alpine peak, this Tasmanian Wilderness World Heritage Area containing ancient Gondwanan rainforests and Australia's deepest lake. It is also a haven for adventure activities such as canyoning, rafting and abseiling.

You’ll see lots of wildlife while you’re touring, including wombats, quolls, wallabies, pademelons and possibly Tasmanian devils.

Best time to visit: Summer (December to February) is best for hiking. If you want to experience snow, visit in winter (June to August).

Travellers can also combine Cradle Mountain with a broader Tasmania road trip, using Launceston as a practical northern gateway or continuing south to Hobart and other island destinations.

Ideal trip length:  3-4 days for a road trip with day hikes.

How to experience it: The Overland Track is a world-class hiking trail located within the park. It takes six days to walk the 65km trail so plan carefully and ensure you have appropriate clothing and supplies for the elements.

There are plenty of stunning walks to do in this region. From short trails through old-growth rainforest and around glacial lakes, to the strenuous six-hour Cradle Mountain Summit, there is something for people at all levels of fitness.

What to know before booking: Campervans, motorhomes, caravans, and trailers are not allowed on Dove Lake Road so you have to park at the Cradle Mountain Visitor Centre and catch the shuttle bus to the major sites.

7. Kimberley, Western Australia

Why it’s special

The colours of the Kimberley, one of the world's last truly remote wilderness areas, are mesmerising. From the beehive domes of the Bungle Bungles to the pearling history in Broome, the thermal springs of El Questro Wilderness Park and the freshwater lakes teeming with crocodiles, the rugged landscapes of the Kimberley attract visitors from all over the globe.

Best time to visit: Dry Season from May to October, when the weather is mild and dry with endlessly blue skies.

Broome is a common starting or finishing point for Kimberley journeys and can be combined with an expedition cruise, guided tour or longer road trip through the region.

Ideal trip length: 2 - 3 weeks

How to experience it: Because many Kimberley highlights are remote, organised 4WD tours and expedition cruises can make access easier by providing suitable transport, expert guides and planned entry to locations reached by rough roads, walking tracks or small boats. They may include places such as the Bungle Bungle Range, Mitchell Falls, remote rock art sites, Horizontal Falls and Montgomery Reef. Experienced travellers can also self-drive parts of the region with a suitable vehicle, a carefully planned itinerary and up-to-date advice on road and weather conditions.

What to know before booking: Plan to travel during the dry season between May and October. This is when road conditions are safe and tourist sites are accessible. From June to August is peak season so if you want to travel during these months, book your tours and accommodation as far as possible in advance.

8. Kangaroo Island, South Australia

Why it’s special

For lovers of nature, wildlife, beach time and good food, Kangaroo Island is a highlight of South Australia holidays and an untouched sanctuary of native wildlife, dramatic coastal landscapes, and unique local produce isolated from the mainland of Australia.

Best time to visit: Summer (December to February) is ideal for beach time and water activities. Autumn to winter (March to September) is best for wildlife spotting and is far less crowded.

Many travellers begin in Adelaide and continue by road to Cape Jervis for the ferry, making Kangaroo Island easy to combine with an Adelaide, Adelaide Hills or South Australian wine-region stay.

Ideal trip length: 3 - 4 days

How to experience it: Book an Ocean Safari tour to swim with seals and dolphins, or a foodie tour to taste wine, gin, honey and seafood fresh from the island. Kangaroo Island offers stunning coastal wilderness, iconic Australian wildlife, and exceptional local food and wine.

What to know before booking: Car and passenger ferries run between Penneshaw Terminal on the island and Cape Jervis Terminal on the mainland, about 12 times a day (45 minutes). Book ahead in the high season, especially if you want to take your car on the ferry.

Qantas flies once or twice a day between Adelaide and Kingscote Airport on the island. There’s no public transport here, so you’ll need to hire a car or book a guided tour if you’re flying in.

Be careful driving at dusk and dawn as wildlife is very active. Also, check the quarantine rules as biosecurity laws are in place to protect the unique island environment.

Practical planning: how to choose where to go and when

How do you choose where to go and when?

Australia’s natural wonders are spread across very different climates, from the steamy tropical north to the hot desert centre, the snowy alpine climates and the cool southern regions. The time of year determines factors like heat, humidity, access, wildlife, reef visibility, road conditions, school holidays and tour availability.

How a travel agent can help

If you’re planning holidays around school terms and work schedules, knowing how and when to book tours to make the most of your time is critical, especially if you only have a few days in a destination. Nothing ruins a holiday quicker than the disappointment of not being able to book activities while on the road.

That’s where working with a trusted travel agent can make all the difference. They can help find the best destinations to visit that work with your timeframe, budget, fitness level and preferred travel style. If you have limited time, an agent can help prioritise the most rewarding experiences, plan smooth train, bus or airport connections, build in realistic travel days, and suggest guided tours, rail journeys or packages. They understand the important limitations of seasonal closures and have expert insights into booking requirements.
