I was a major skeptic of the abilities of the Bus 4×4 conversions but and when the head engineer told me to drive a newly hired Coaster for our Adventure Tour, I did it with apprehension. I drove the bus down to Inskip Point for my first soft sand challenge, stopping just before the really soft sand to lock it into low range. To my surprise, without changing gears, I was able to get the Coaster out of the soft sand onto the hard wet sand before the barge without any issues.

There was nothing that seemed to worry this bus, it drove through everything the island threw at us in normally dry boggy testing conditions in sand. I would not hesitate to buy one!

Bus 4×4 was established 10 years ago to meet the need for quality, reliable and roadworthy 4×4 people movers in the mining, resources and remote community sectors of Australia. We understood the most cost-effective way to transport sizable numbers of passengers in off-road conditions would be to convert existing 2-wheel drive buses into 4×4 vehicles.

After several years of Research and Development, Bus 4×4 concluded that the most reliable platforms to convert into 4×4, due to their popularity, ease of conversion and availability of spare parts, were the Toyota HiAce and Toyota Coaster. Bus 4×4 worked for many more years to perfect the ‘Full Time AWD with High and Low Range 4×4 Conversion Kit’ to suit Toyota HiAces and Toyota Coasters for safe, reliable off-road driving in challenging terrain worldwide.

Bus 4×4 has come a long way from the first prototype tested almost a decade ago to the latest AWD Conversion Kit. The 4×4 conversions from Bus 4×4 are some of the most sought after people movers in the mining and tourism sector.

As a fast growing company, Bus 4×4 has converted a combined total of over 1000 vehicles to four-wheel drive. Bus 4×4 also exports 4×4 Conversion Kits to Southern Africa, PNG, Europe, Japan, Middle East and Dominican Republic.

We are leaders in our sector and active members of QBIC (Qld Bus Industry Council), BIC (Bus Industry Council), ICN (International Capability Network), AIDN (Australian Industry & Defence Network) and Queensland Leaders. We have been finalists, twice in the Small Business Champion Awards in 2017 and 2019.
