Australian indigenous architecture

Depend on the availability and supply of materials, Aboriginal people in each region will construct the suitable house. Each type of construction has different dome frameworks material (cane, stone, and timber) as well as the structures (arc-shaped, triangular, egg-shaped). House are designed for using in many years by a same family group.
• In cold regions of south eastern Australia: stone house
• In the Western Desert: Spinifex shelters
• In the Lake Eyre region: waterproof dome shelters

Dome-shaped shelters: this type of construction is extend across Australia and used for temporary even permanent structures.

• Well-constructed, grass-clad dome structures: permanent camps at Crawley on the Swan River, Western Australia
• Mud with grass are used to waterproof the dome shelters, circular stone-walled houses: the Lake Eyre region, South Australia

Spinifex shelters: Windbreaks architecture of spinifex or hummock grass as cladding over domed frames dominated. 

• Piled-up of Acacia or Cassia species with gaps filled in with grass, circular arc, a crescent or linear form with the wall always to windward, semi-open: the Western Desert region.
• Dome-shaped semi-enclosed wiltjas, upright mulga boughs inserted into holes, the brushy ends upwards, outer covering of tussock grass,the maximum internal height: 1.7 metres: the Warburton Ranges

Stone house: a part of a range of Indigenous stone engineering structures including stone-walled fish traps in the sea and rivers, weirs, canals, ovens and ceremonial stone layouts on the ground.
