Fuel costs for your motorhome roadtrip journey

Fuel is one of the main costs to plan for when travelling around Australia or New Zealand. Prices can vary depending on where you are, your route, and current fuel rates, so it’s helpful to build a simple estimate before you set off.

If you have made a decision on what motorhome or campervan you hope to travel in, have a rough route in mind; a quick check on current pump prices before you go can help you get a you realistic cost estimate in just a few minutes. Think of this page as a friendly planning guide: clear, practical, and transparent.

 

Fuel prices across Australia & New Zealand

Fuel prices can differ depending on location:

Australia: Prices are often higher in remote or regional areas, especially in the Outback 

New Zealand: Prices can vary between islands and regions, especially in the main city Auckland. 

Plan your fuel stops and check pricing ahead of your journey by using popular apps and websites such as:

New Zealand Gaspy

 

What recent global news means for travellers

Disruption to oil supply, refining, or shipping routes typically cause fluctuation in gas prices at the pump. This is one reason prices may feel unpredictable from week to week.

The practical takeaway for guests is simple: build your estimate using current prices, expect some movement, and re-check prices along the way. Planning with a small buffer can make the whole trip feel more relaxed and less uncertain.

 

Travelling smart: how to drive less, save money, and still enjoy the journey 

Typical fuel usage 

Fuel consumption varies by vehicle size and driving conditions, so is a tricky one to gauge. However, this fuel tank planning guide should help you estimate costs quickly, before travel. Because assigned vehicles can vary within a category, exact tank capacity may differ slightly from one vehicle to another. The right way to use these numbers is as a practical planning starting point rather than a guaranteed exact fill amount.

For example, if your motorhome has a 71-litre tank and diesel is AUD$3.16 per litre, a full fill-up would cost about AUD$224.36. If the same fuel is AUD$3.30 per litre, that same fill-up would cost about $234.30. If your motorhome has a 100-litre tank and diesel is AUD$3.16 per litre, a full fill-up would cost about AUD$316. If the same fuel is AUD$3.30 per litre, that same fill-up would cost about $330. That is why fuel prices can make a noticeable difference from one route to another. 

Guests can use this simple math at any point during their trip. Just check the fuel price at a station, multiply it by the estimated tank size for your campervan or motorhome, and you will have a quick refill estimate for budgeting purposes. 

These are planning estimates; your exact vehicle may differ slightly. Your total fuel cost will depend on a number of factors from how far you travel, the terrain (mountains, highways, gravel roads), the weather and individual driving style.  

To help you prepare, we’ve put together a few tips for fuel-efficient travel: 

  • Drive at a steady pace and avoid unnecessary idling. 
  • Refill water tank once you arrive at your next campsite to reduce weight as you drive to the next campsite. 
  • Linger for longer - Spend more time at each destination to reduce daily driving distances.  Explore each destination in more detail and enjoy getting closer to the destination. 
  • Use our trip planning tools, itineraries and our thl Roadtrip app to find campsites and things to see and do. 
  • At pick-up speak with our team for route suggestions that optimise fuel access and efficiency. 
  • Check fuel prices regularly during your trip. We also suggest filling up before heading into remote areas.

5-Day Caves Road Itinerary: A Margaret River Campervan Road Trip from Perth

5-Day Caves Road Itinerary: A Margaret River Campervan Road Trip from Perth

Day 1: Perth to Dunsborough 

Distance: 242 kms 
Travel time: ~3 hours 

Pick up your Apollo camper in Perth and head south to begin your Western Australia road trip. This first drive is long enough to feel like you have escaped the city, but easy enough to keep the day relaxed. Rather than pushing all the way through the Margaret River region in one go, stopping in Dunsborough gives you time to ease into the trip, enjoy the coast, and settle into holiday mode before the cave-hopping begins. 

Where to stop between Perth and Dunsborough 

Bunbury is a great first pause on the way south. Koombana Bay is a pleasant place to stretch your legs, enjoy the waterfront, and reset after leaving Perth behind. From there, continue to Busselton, where the famous jetty makes a classic stop on any southwest road trip. Even a short wander along the foreshore gives you wide bay views and that unmistakable holiday feeling. If you want to keep the day easy, pick up picnic supplies before reaching Dunsborough so you can enjoy a simple meal near the water once you arrive. 

Things to do in Dunsborough 

Dunsborough is a relaxed first overnight stop on a slower-paced Margaret River road trip. Start with something simple and local, such as a visit to Dunsborough Bakery for fresh bread, pastries, pies, or something sweet for afternoon tea. If your timing lines up, Markets by the Bay is also worth a browse, typically running on the second Saturday of the month during the warmer-season market period. The foreshore is ideal for an easy evening walk, and the calm bay helps set the tone for the days ahead. This is not a day to overfill. It is a day to arrive, breathe out, and enjoy the shift from city pace to coastal rhythm. 

Where to stay in Dunsborough 

Book a powered site at a campervan-friendly holiday park such as BIG4 Dunsborough Southern Stars Holiday Park. It is well placed for access to town, nearby beaches, and the northern end of Caves Road, making it a practical and comfortable first-night base. If you are happy to stay a little farther south on the bay, Discovery Parks, Busselton is another solid option with easy access to tomorrow’s route. 

 

Day 2: Dunsborough to Margaret River 

Distance: 47 kms 
Travel time: ~1 hour 

Today is where your Caves Road itinerary really begins. The driving distance is short, which gives you the freedom to turn this into a full day of exploring rather than simply getting from A to B. Between Dunsborough and Margaret River, the landscape shifts between coastal viewpoints, bushland, and limestone country, making this one of the most scenic sections of the whole trip. 

Where to stop between Dunsborough and Margaret River 

Your first major stop should be Ngilgi Cave near Yallingup. It is a great introduction to the region’s cave systems because the experience starts above ground, with an interpretive bush trail that adds context to the geology and environment before you head below. Inside, the self-guided cave walk reveals chambers filled with intricate formations, creating an atmospheric and accessible first cave visit. After Ngilgi Cave, continue south at a gentle pace and stop at places such as Yallingup Beach or Sugarloaf Rock for sea views and fresh air. These lookouts are perfect for photos, a thermos coffee, or simply taking a few quiet minutes to watch the ocean. 

If you would like to include a winery stop, this part of the region offers plenty of choice. Keep it modest and plan around the fact that you are still driving to Margaret River town. One tasting with lunch is a far better fit for a campervan road trip than trying to cram in multiple cellar doors. This stretch of Caves Road captures exactly why the route is so loved. Forest, vines, and coastline sit close together, and every short detour seems to reveal another inviting stop. 

Things to do in Margaret River 

Once you arrive in Margaret River, spend the afternoon leaning into the region’s food culture. Margaret River Bakery is a popular stop for pastries, coffee, and casual meals, while Margaret River Woodfired Bread is ideal if you want to build your own picnic with excellent bread and local ingredients. If you arrive on a Saturday morning, Margaret River Farmers’ Market is one of the best local produce stops in the area, with a lively atmosphere and plenty of seasonal flavours to take back to the camper. Later, slow the pace right down with an easy walk near the river or a relaxed picnic in one of the town’s green spaces. This is the kind of afternoon that suits a campervan itinerary perfectly. 

Where to stay in Margaret River 

Margaret River Tourist Park is a strong choice for campervan travellers who want easy access to town while still having a peaceful base. Riverview Tourist Park is another good option, especially if you prefer a leafier, slightly quieter setting. Both work well for an Apollo camper and put you in a handy position for tomorrow’s forest and cave experiences. 

 

Day 3: Margaret River to Augusta 

Distance: 44 kms 
Travel time: ~1 hour 

This is one of the standout days of the trip. The drive south from Margaret River to Augusta is short, but the number of memorable stops packed into this stretch makes it feel wonderfully full. With dramatic cave systems, towering karri forest, and the chance to see a wilder side of the southwest coast, today has the strongest sense of adventure on the itinerary. 

Where to stop between Margaret River and Augusta 

Start with Lake Cave, one of the most visually striking caves in the region. The descent into the sinkhole is part of the experience, and once inside, the still underground lake creates beautiful reflections beneath delicate formations. Continue to Mammoth Cave, where the experience becomes as much about natural history as visual drama. The self-guided walk passes through large chambers associated with fossils of long-extinct megafauna, adding a fascinating layer to your Caves Road itinerary. 

From there, the route through Boranup Forest is a highlight in its own right. Driving beneath the tall karri trees feels almost cathedral-like, and it is well worth pulling over safely for a short walk and a picnic if you have stocked up earlier in the day. Before reaching Augusta, make time for Jewel Cave near Hamelin Bay. This cave is known for its large chambers and richly decorated formations, making it a fitting grand finale to the day’s cave experiences. If you are not ready to head straight into town after that, Hamelin Bay is a lovely detour for a beach walk and a breath of sea air. 

Things to do in Augusta 

Augusta has a quieter, more tucked-away feel than the towns farther north, which makes it a rewarding overnight stop after a day of exploring. Spend the evening near the water, enjoy a simple dinner in the camper, and take in the slower pace of the southern end of the region. A foreshore walk is a gentle way to end the day, especially as the light softens and the big coastal sky starts to glow. This part of Western Australia feels remote in the best possible way. 

Where to stay in Augusta 

Flinders Bay Caravan Park is an excellent campervan-friendly base for the night, offering a peaceful coastal setting and easy access to the bay for an evening stroll. Augusta Caravan Park is another practical option if you prefer to stay closer to town facilities. Either choice keeps the day simple and suits a relaxed campervan road trip well. 

 

Day 4: Augusta to Busselton 

Distance: 130 kms 
Travel time: ~2 hours 

After yesterday’s cave-focused adventure, today shifts toward the gourmet and scenic side of the Margaret River region. You will travel back north through vineyard country toward Busselton, with plenty of flexibility for a long lunch, a beach stop, or a few carefully chosen local experiences. The key to this day is not trying to do everything. It is about choosing a few memorable stops and enjoying them properly. 

Where to stop between Augusta and Busselton 

Take your time heading north and choose one or two cellar doors rather than trying to fit in too many. The Margaret River region is home to more than 200 wineries, with Cabernet Sauvignon and Chardonnay among its best-known varieties, so there is no shortage of places to stop. For campervan travellers, a winery lunch is often the best approach, letting you enjoy the setting and local produce without rushing from tasting to tasting. If you are travelling from late February through April, you may catch the vineyards during harvest season, which adds extra atmosphere to the region. 

This is also a good day to include a bakery, farm-gate stop, or a scenic beach pause if you would rather keep things low-key. A quiet coastal walk, a picnic, and one excellent food or wine experience can make this leg feel especially rewarding. Just remember that if wine tasting is on the plan, someone must remain the designated driver, or tastings should be limited to suit safe travel in the campervan. 

Things to do in Busselton 

Back in Busselton, the foreshore and jetty area make an easy and classic place to spend the afternoon. Even if you stopped here on day one, it feels different when you return without a long drive still ahead of you. Stroll part of the timber jetty, enjoy the bay views, or simply settle in by the water with takeaway fish and chips or a picnic dinner. After several days of caves, forests, and country roads, Busselton’s easy seaside atmosphere is a lovely way to round out the coastal part of the trip. 

Where to stay in Busselton 

Discovery Parks, Busselton is a reliable campervan option with beach access and good facilities, making it ideal for a final night on the coast. BIG4 Breeze Holiday Parks, Busselton is another solid choice if you want a well-equipped holiday park close to town and the waterfront. Both suit an Apollo camper and make the return drive to Perth straightforward the next day. 

 

Day 5: Busselton to Perth 

Distance: 227 kms 
Travel time: ~3 hours 

Your final day is an easy drive back to Perth, but there is no need to rush away unless your return schedule demands it. One more slow morning by the coast is a fitting end to the trip. Enjoy breakfast near the water, take a short walk, and savour the last of that southwest holiday feeling before you turn north. 

Where to stop between Busselton and Perth 

If you want to break up the return drive, Bunbury is again a convenient place to stop for coffee or lunch. Otherwise, keep things simple and enjoy the familiar route as it carries you back toward the city. Loop itineraries have a satisfying rhythm, and this final leg gives you time to reflect on the caves, forests, coastline, and good food that filled the last few days. 

Things to do in Perth 

Once back in Perth, you may have time for one final easy stop before returning the camper. If your schedule allows, a relaxed afternoon in the city or near the coast can help stretch the holiday mood a little longer. If not, simply head back to the Apollo branch, return the vehicle, and finish the trip with plenty of ideas for where to roam next in Western Australia. 

Where to stay in Perth 

If you are extending your trip by a night, choose a campervan-friendly holiday park such as Discovery Parks, Perth Airport or Karrinyup Waters Resort. Both are practical options before or after your Apollo branch return. If your journey ends today, return the camper to the Apollo Perth branch and wrap up your loop there.
