This 2004 Swagman Australis 28 offers a distinctive take on the large Australian-built motorhome, combining substantial mechanical specification with a floorplan designed around comfortable long-distance touring. With 176,746 kilometres, it is powered by a 3.9L four-cylinder diesel engine paired with an Allison automatic transmission and sits on a Roadmaster chassis with a 9,980kg GVM. Inside, the front living area sets the Australis apart from the more conventional Signature 28 layout. Four individual swivel seats are arranged around two flip-up tables, creating a comfortable face-to-face living space while allowing the front seats to swivel into the living area when parked. For longer stays, the Australis is equipped with a substantial electrical and touring package, including four 190Ah AGM house batteries, solar charging, a 1,500VA inverter and a 3.6kVA Onan generator. Two house air-conditioners, a diesel heater, front-load washing machine, 3-way fridge/freezer and hot water system further add to its touring capability.

Swagman Australis 28 Full Description
A Distinctive Australian-Built Motorhome
The Swagman Australis was built for travellers looking for considerably more than basic accommodation on wheels. At 28 feet in length and riding on a Roadmaster chassis with a 9,980kg GVM, this is a substantial motorhome with the mechanical specification to match its size.
The 3.9L four-cylinder diesel is paired with an Allison automatic transmission, while cruise control, power steering, reversing camera and cabin air-conditioning add to the driving experience.
For touring flexibility, the chassis is also equipped with a hydraulic stabilising system, bull bar, driving lights, UHF radio and a towbar rated to 2,300kg.
Four-Seat Swivel Living Area
The front living area is one of the most distinctive features of this Australis 28.
Rather than the conventional lounge and dinette arrangement found in the Signature 28, this motorhome uses four individual swivel seats with two flip-up tables positioned between them. Once parked, the seats can be swivelled towards the living area to create a comfortable four-person space for dining, conversation or relaxing.
This arrangement also retains four individual, supportive seats rather than relying on a fixed lounge.
Practical Touring Interior
Moving through the motorhome, the kitchen and ensuite are positioned opposite each other before the layout opens into the rear bedroom.
The kitchen is equipped with a 3-way fridge/freezer, microwave, hot water system and filtered tap, while the interior features leather upholstery and USB outlets.
A front-load washing machine adds another practical feature for extended trips, reducing the need to rely on laundries while travelling.
Rear Island-Bed Bedroom
At the rear, the Australis provides a dedicated bedroom with a north/south island bed.
The island configuration provides access around both sides of the bed and gives the rear of the motorhome a more residential feel, while the separation from the front living area creates distinct zones for daytime living and sleeping.
Substantial Power & Climate Equipment
The Australis has been equipped with a considerable onboard electrical system for a motorhome of its era.
The house system includes four 190Ah AGM batteries, providing 760Ah of nominal battery capacity, together with a battery monitor, solar charging system and 1,500VA inverter.
A 3.6kVA Onan generator provides an additional source of onboard power, while two house air-conditioners and a diesel heater provide options for managing the interior temperature in different conditions.
Two 4 Seasons hatches also provide additional ventilation and airflow.
Chassis & Driving Features
Built on a Roadmaster chassis, this Swagman is powered by a 3.9L four-cylinder diesel engine coupled to an Allison automatic transmission.
The 9,980kg GVM places the motorhome in the MR licence category, so an appropriate Medium Rigid truck licence is required to drive it.
Chassis and driving equipment includes cruise control, power steering, cabin air-conditioning, Bluetooth stereo, reversing camera, hydraulic stabilising system, bull bar, driving lights, UHF radio and a 2,300kg-rated towbar.
Dealer’s Note
The Australis 28 is an interesting motorhome because the layout is quite different from the more familiar Signature 28. The four swivel seats and individual flip-up tables create a very usable front living area without relying on a conventional lounge, while the rear island bed gives the bedroom a more residential feel. Combined with the Roadmaster chassis, Allison automatic, substantial AGM battery bank, Onan generator and dual house air-conditioning, it is a motorhome that was clearly designed with extended touring in mind.
