Pick a state
Each of the eight destination guides covers the main driving corridors in that state, the national parks worth the detour, realistic distances between towns, and the months that actually work.
Clear Horizons is an independent online guide to travelling inside Australia by road. We publish distances, driving times, road surfaces, seasonal windows and campsite notes — the details that decide whether a trip works, not the adjectives.
Most Australian trips are decided by driving time. Sydney to Byron Bay is roughly 770 km and takes about nine hours without stops, which makes it a three-day trip rather than a weekend. Adelaide to Perth along the Eyre Highway is about 2,700 km — realistically four long days of driving, with fuel stops spaced far enough apart that the gap between them, not the total distance, sets your daily plan. Melbourne to the eastern end of the Great Ocean Road is under two hours, but the road itself averages closer to 45 km/h once you are past Lorne because it is narrow, winding and busy.
Every guide on this site opens with the same block of figures: distance in kilometres, realistic driving time including stops, sealed or unsealed surface, the practical season, and where mobile coverage is unreliable. If a route needs a high-clearance four-wheel drive, we say so in the first paragraph rather than the last. If a road closes for months at a time — as the Gibb River Road in the Kimberley does through the wet season — that closure is treated as the headline fact about the route, because it is.
A cross-section of what the guides cover, from a two-day coastal run to a two-week crossing.
Short in kilometres, long in hours. Three days lets you drive the Otway section in daylight and reach the Twelve Apostles outside the middle-of-the-day coach window.
Alice Springs, the West MacDonnell Ranges, Kings Canyon and Uluru-Kata Tjuta. Doable in five days; six removes the day where you drive four hours and see nothing.
Kalbarri, Shark Bay and Ningaloo Reef on one sealed corridor. The detour into Denham adds 260 km return and is worth a full day rather than a stop.
Freycinet, the Bay of Fires and the Tasman Peninsula. Small distances, but the ferry booking and the summer accommodation squeeze are the real constraints.
Wilpena Pound and the Ikara-Flinders Ranges National Park, with the unsealed northern tracks as an optional extension for the right vehicle.
A long, flat, mostly two-lane highway. Plan it as five driving days plus three stationary ones, not eight days of continuous movement.
Australia is large enough that "summer holidays" means opposite things depending on latitude. South of roughly the Tropic of Capricorn, the best driving months are the shoulder seasons: March to May and September to November, when daytime temperatures sit in a workable range and school-holiday traffic has eased. Tasmania is the exception in the south, where December to March is the only reliably warm window and everything books out well ahead.
North of the Tropic — the Top End, the Kimberley, Cape York and inland Queensland — the year splits into a dry season from roughly May to September and a wet season from November to March. In the dry, the days are warm, the roads are open and the humidity is manageable. In the wet, unsealed roads close, river crossings become impassable and some national parks shut entirely for months. This is not a preference; it is a hard constraint that determines whether a route exists at all in a given month.
Inland, the constraint is heat. Summer daytime temperatures across central Australia routinely sit above 40 °C, which makes walking tracks unsafe in the middle of the day and puts real strain on vehicles and cooling systems. Our when to go guide breaks this down region by region and month by month.

The trip planner filters more than 40 routes by state, number of days, trip type, month and where you intend to sleep. It runs entirely in your browser and saves your shortlist locally.
Our distance and fuel guide, outback packing list and park pass overview cover what the route pages assume you already know.
Clear Horizons does not sell tours, take bookings, run affiliate links or accept payment for coverage. There is no advertising inside the guides and no sponsored placement in the trip planner. When a route or park requires a fee, we say that a fee applies and point you to the relevant state park service — we do not quote dollar figures, because those change and a stale number is worse than none.
We also do not publish reader reviews or star ratings. Where a page carries an opinion, it is signed by a named member of the small editorial team listed on our about page, and the reasoning behind it is written out. Our editorial policy sets out how the information is checked, how often each guide is reviewed, and how to tell us when something is wrong.
The most common planning mistake we see is treating the map distance as the trip. On a sealed highway with no towns you might average 90 km/h. On the Great Ocean Road, the Great Alpine Road or anything in the Tasmanian highlands, 55 km/h is a fairer figure once you include stops, and it drops further with a caravan behind you. Build the itinerary from hours, then check the kilometres — not the other way around.
