You don’t need a dozen apps to plan a Big Lap. You need three, and you need to know what each one is good at and where it falls short. WikiCamps finds your camps. Hema gets you there safely. Google Maps fills the gaps. Together they handle every planning decision you’ll make on the road, from “where are we sleeping tonight?” to “is there a mechanic in the next town?”

This guide walks through each app in detail: how to set it up, how to use it effectively, and the specific tricks that experienced Big Lappers rely on. If you’re new to any of these, spend 30 minutes with this guide before you leave home and you’ll be planning like a veteran within a week on the road.

Three apps, three jobs. WikiCamps finds your camp, Hema navigates the back roads, Google Maps handles everything else.


The Three-App System

Each app has a clear role, and understanding the boundaries prevents you from using the wrong tool for the wrong job.

WikiCamps Australia is your accommodation database. It answers: where can I camp tonight? What facilities does it have? Is it free or paid? What did other travellers think of it? How do I get there? It’s the single most important app on your phone.

Hema Explorer is your off-road navigator and road condition reference. It answers: what’s the road like? Is it sealed, gravel, or 4WD only? Where are the fuel stops on this stretch? What’s the terrain like? It replaces Google Maps anywhere the bitumen ends.

Google Maps is your general-purpose tool. It answers: how far is it? How long will it take? Where’s the nearest supermarket, mechanic, doctor, or fuel station in this town? It’s the best tool for sealed-road navigation and finding services, but it knows nothing about camp quality and can’t be trusted on unsealed roads.

The mistake most beginners make is relying on Google Maps for everything. It works fine for the first few weeks on the east coast. Then you hit a gravel road it doesn’t know about, or it routes you down a track your caravan can’t handle, or it shows a “campground” that turns out to be a locked gate and a muddy paddock. That’s when the other two apps earn their keep.


WikiCamps: Finding Where To Stay

The Basics

WikiCamps is a one-off purchase (around $8, no subscription) available on iOS and Android. It contains a crowd-sourced database of campgrounds, caravan parks, free camps, dump points, water refill stations, rest areas, information centres, and points of interest across Australia. Users submit new listings and review existing ones, so the data is constantly updated by the travelling community.

How To Search Effectively

Map view is the most intuitive way to find camps. Zoom into the area you’re heading to and the pins appear. Colour-coded: green for free camps, blue for paid parks, orange for dump points, and so on. Tap a pin to see the listing, facilities, reviews, and photos.

Filter religiously. WikiCamps has extensive filters: camp type (free, paid, national park), facilities (toilets, water, showers, power), pet-friendly, size limits, 2WD accessible, and more. If you’re towing a 22-foot van with a dog and need water and toilets, set those filters once and save them. You’ll use this saved filter daily.

Read the recent reviews, not just the rating. A camp with a 4-star rating might have been 5 stars six months ago and 2 stars last week because the council closed the toilets or the access road washed out. Sort reviews by “most recent” and read the latest 3 to 5 before committing. Travellers are excellent at flagging issues, road conditions, and whether the photos still match reality.

Check the “Last Visited” date. A listing that hasn’t been reviewed in 2 years might no longer exist. Councils close free camps, parks change management, and roads deteriorate. Recent reviews mean current information.

WikiCamps Power Tips

Use the “Trip Planner” feature. You can plot your route and WikiCamps shows all listings within a set distance of your path. This is brilliant for finding camps you’d otherwise miss, and for identifying gaps where there’s nothing available (so you know to fill up on water and plan accordingly).

Download data before you leave. WikiCamps works offline, but only with data you’ve already synced. Before departure, open the app on Wi-Fi and sync the full database. Re-sync whenever you have a strong connection. In remote areas with no signal, the offline data is your only reference.

Save favourites and create lists. When someone at the campfire recommends a spot, open WikiCamps, find it, and save it to a list. “Recommendations,” “Must-Visit,” “Backup Options.” These lists become invaluable as the trip progresses.

πŸ’‘
Tip

Always identify 2 to 3 camp options for each night, not just one. Your first choice might be full, closed, or not as advertised. Having backups means you’re never scrambling at 4pm with nowhere to sleep.

Hema Explorer: Getting There Safely

The Basics

Hema Explorer is a subscription-based app (around $50/year or lifetime purchase) built specifically for Australian off-road and remote navigation. It includes topographic maps, road condition ratings, track difficulty levels, fuel station locations, water points, and points of interest. The maps are available offline, which is essential for remote travel.

When To Use Hema Over Google Maps

Any unsealed road. Google Maps often doesn’t distinguish between a well-maintained gravel highway and a deeply rutted 4WD track. Hema does. Its road condition ratings (sealed, maintained gravel, dry-weather only, 4WD required) tell you whether your 2WD and caravan can handle a road before you’re committed to it.

Remote fuel planning. Google Maps shows the nearest fuel station but doesn’t always know whether it’s open, whether it has diesel, or whether it’s a 24-hour card-operated pump versus a staffed servo that closes at 5pm. Hema’s fuel station data is more detailed and more relevant for remote travel.

When you have no signal. Google Maps’ offline mode is limited and clunky. Hema’s offline maps are its core feature. Download entire states before you leave and navigate with full detail anywhere in the country, signal or not.

Checking road conditions and closures. Hema integrates with state road authority data to show current road conditions and closures. This is critical in the Top End approaching wet season, across the outback after rain, and anywhere that unsealed roads might be affected by weather.

Hema Power Tips

Download maps for your entire route before you leave. Each state’s map data is a substantial download. Do this on home Wi-Fi, not at a caravan park where the connection is shared between 200 vans.

Use the “measure distance” tool to check actual driving distances on back roads. Google Maps’ estimates for unsealed roads are often wildly inaccurate because it assumes highway speeds. Hema gives more realistic distances and helps you plan fuel stops on remote stretches.

Check the legend. Hema’s colour-coded roads take a few minutes to learn but become second nature. Red dashed lines mean very different things to green solid lines. Understanding the legend prevents you from turning onto a road your van can’t handle.


Google Maps: The Glue That Holds It Together

What Google Maps Does Best

Distance and time estimates on sealed roads. Google Maps’ routing algorithm on bitumen is excellent. If you’re driving Highway 1 from Cairns to Townsville, Google Maps gives you the most accurate time estimate of any app. Use it for planning driving days and estimating arrival times.

Finding services in towns. Need a mechanic in Geraldton? A supermarket in Katherine? A laundromat in Esperance? A doctor in a small town? Google Maps’ business listings, hours, and reviews are unmatched. WikiCamps and Hema don’t cover this.

The “Saved Places” and lists feature. Create lists like “Must-See Stops,” “Fuel Stations,” “Recommendations From Travellers,” and “Mechanics Along Route.” Pin locations as you discover them. Over the course of the trip, you build a personalised map of your entire journey’s useful stops.

Where Google Maps Falls Short

Unsealed roads. Google Maps frequently routes you onto roads that are unsuitable for caravans, including 4WD-only tracks, unmaintained farm roads, and seasonal roads that are closed. It doesn’t show road conditions, doesn’t know about towing restrictions, and doesn’t understand that your 8-metre rig can’t make a hairpin turn on a narrow mountain track.

Remote fuel stations. Google Maps sometimes shows fuel stations that have closed, or misses small independent servos and roadhouses that Hema knows about. In remote areas, always cross-reference with Hema or a fuel price app.

Campsite quality. Google Maps shows campgrounds as locations, but has no useful information about facilities, suitability for caravans, recent conditions, or whether it’s actually worth stopping at. WikiCamps is the only reliable source for this.

⚠️
Important

Never blindly follow Google Maps onto an unsealed road while towing a caravan. Always cross-reference with Hema’s road condition data first. Google Maps has sent caravanners down 4WD tracks, flooded roads, and dead ends. Trust it on bitumen; verify it off bitumen.


Using All Three Together: The Daily Workflow

Here’s how the three apps work together in practice, day by day on the road.

The evening before (5 to 10 minutes): Open WikiCamps and identify 2 to 3 camp options for tomorrow night. Read recent reviews. Check the access road: is it sealed, gravel, or rough? If there’s any doubt, open Hema and check the road condition rating. If you’re booking a park, call or book online.

Morning before driving (2 to 3 minutes): Enter tomorrow’s destination into Google Maps for the time estimate. If any part of the route is unsealed, switch to Hema for that section. Check road conditions on Hema if you’re in an area affected by recent weather.

On the road: Navigate using Google Maps on sealed highways (better real-time traffic and routing). Switch to Hema if you leave the bitumen. If you decide to change plans mid-drive (a common and wonderful occurrence), check WikiCamps for camps in the new area and re-route.

At camp: If someone recommends a spot, look it up on WikiCamps and save it to a list. Check Google Maps for any services you need in the nearest town (shops, laundry, fuel). Spend 2 minutes looking at Hema for tomorrow’s road conditions.

The whole process takes 10 to 15 minutes per day once you’re in the rhythm. Most of that is the evening camp-finding session. The rest is quick glances at the right app at the right time.

Setup Before You Leave

Spend an hour at home setting up these three apps properly and you’ll save hours of frustration on the road.

WikiCamps: Buy the app. Sync the full database on Wi-Fi. Set up your default filters (van length, facilities needed, pet-friendly if applicable). Create empty lists for “Recommendations,” “Must-Visit,” and “Backup Camps.” Add any camps you’ve already identified from your initial planning to the Must-Visit list.

Hema Explorer: Subscribe or purchase. Download offline maps for every state on your route (do this on home Wi-Fi; the downloads are large). Familiarise yourself with the road condition legend and the fuel station symbols. Practise measuring a distance on a back road near home so you know how the tool works.

Google Maps: Download offline maps for your first leg (Google Maps offline covers a smaller area per download than Hema, so you’ll need to re-download as you travel). Create your saved lists. Pin your must-see destinations, any pre-booked parks, and known fuel stops for remote stretches.

All three: Do a test run. Pick a destination 200km away, use WikiCamps to find a camp there, use Hema to check the road, and use Google Maps to estimate the drive time. If you can do that smoothly at home, you’ll be fine on the road.

Key Takeaway
  • WikiCamps finds your camps (use filters, read recent reviews, always have 2 to 3 options). Hema navigates safely (road conditions, offline maps, fuel planning). Google Maps handles distances, services, and sealed-road routing.
  • Never follow Google Maps onto an unsealed road without checking Hema first. Google Maps doesn’t know the difference between a highway and a 4WD track.
  • Download all offline data before you leave home. WikiCamps, Hema, and Google Maps all have offline modes, but they only work with pre-downloaded data.
  • The daily workflow takes 10 to 15 minutes: evening camp check on WikiCamps, morning route check on Hema/Google Maps, quick adjustments on the road as needed.
  • Set up filters, saved lists, and offline maps before departure. One hour of setup at home saves hours of frustration on the road.
