Why the Toyota HiAce Dominates Australian Van Life
Walk into any van life gathering in Australia and you will see more HiAces than any other van. There is a good reason for this. The HiAce is affordable, incredibly reliable, cheap to service anywhere in Australia, and has a massive community of builders who have already solved every problem you will encounter. It is the safest first conversion van you can buy.
Which HiAce Generation Should You Buy?
- Gen 4 (1989–2004): The classic cab-over design. Affordable at A$8,000–$18,000. Simple mechanicals, easy to work on. Limited internal height (1,310mm) means most people cannot stand up. Best for budget first-time converters.
- Gen 5 (2005–2018): Same cab-over design, better safety and features. Popular conversion choice at A$15,000–$30,000. Proven reliability across hundreds of thousands of Australian kilometres.
- Gen 6 (2019–present): Semi-bonneted design, 5-star ANCAP safety, much better to drive. Costs A$30,000–$55,000 used. Higher floor means slightly less internal height but better overall package.
HiAce Dimensions for Conversion Planning
- Internal length (LWB): 2,800mm — enough for a 1,900mm bed plus kitchen
- Internal height (Gen 4/5): 1,310mm — sitting height only
- Internal width: 1,670mm
- 4WD option: Not available
HiAce Conversion Cost in Australia
A HiAce conversion is the most affordable path into Australian van life:
- Van purchase: A$12,000–$35,000
- Basic conversion (bed + insulation + power): A$3,000–$8,000
- Full conversion (solar, fridge, kitchen, heater): A$12,000–$25,000
HiAce Layout Options
The LWB HiAce fits a lengthwise single bed (1,900mm) with a kitchen at the rear, or a transverse double bed if you do not need to stand. The most popular Australian layout is a fixed lengthwise bed along one side with kitchen storage, a 40–50L fridge, and a fold-out table on the opposite side.
Frequently Asked Questions
What is the best year HiAce to convert in Australia?
For the best balance of price, reliability and features, a 2010–2018 Gen 5 HiAce LWB is the sweet spot. These are widely available across Australia for A$15,000–$28,000, have proven reliability, and the conversion community knowledge is extensive.
Can two people sleep in a HiAce conversion?
Yes — a transverse bed arrangement in a LWB HiAce can sleep two people side-by-side at around 1,670mm wide. Alternatively a lengthwise single bed is more comfortable for one person with better use of the remaining space.
Australian Tips
Australia's harsh climate demands proper insulation and ventilation. Install roof vents and fans before your first summer—interior temps can hit 50°C without airflow. For remote travel, carry extra coolant and check belt condition regularly. Dirt roads will shake everything loose, so use thread locker on all bolts. Register your conversion in your home state before travelling—some states have stricter engineering requirements. Keep your original seats and seatbelts if you plan to sell later. Darwin to Perth is 4,000km with limited services, so plan your mechanical servicing stops.
Frequently Asked Questions
What's the best HiAce engine for long-distance touring?
The 3.0L diesel (1KD-FTV) in Gen 5 vans offers the best balance of power and fuel economy for highway cruising and hill climbing with a loaded conversion setup.
How much does a basic HiAce conversion cost in Australia?
Budget A$15,000–$25,000 for a DIY conversion including insulation, basic kitchen, bed, and electrical. Professional builds start around A$60,000 depending on specifications and finishes.
Do I need engineering certification for my HiAce conversion?
Most states don't require engineering for basic fitouts, but modifications affecting seating, suspension, or structural changes may need certification. Check your state's specific requirements first.
Australian Tips
Australia's extreme climate demands proper ventilation and insulation in your HiAce conversion. Install roof vents and consider ceramic window tints for Queensland summers. Our corrugated roads will test every mounting point—use aviation nuts and steel brackets, not timber screws. Check state-specific height restrictions; some tunnels limit 2.1m clearance. Register weight modifications with your state transport authority. Carry spare parts for remote travel—alternator, starter motor, and fuel pump failures are common on older HiAces in outback conditions.
Frequently Asked Questions

The 3.0L 1KD-FTV diesel (Gen 5) offers the best balance of power, economy, and reliability. Avoid early 2.5L D4D engines due to injector problems.
