Between World Wars One and Two, the style derived from the west coast of the US, modified to suit Australian conditions, known as the 'California Bungalow' became popular.
It drew inspiration from a wide range of countries, including England, North America, Japan and Switzerland. Typical features include: pylons supported a flat roof or gable to the porch; shingled gable ends. clinker brick chimneys and rough cast walls.
These two photos are good local examples. The first one reminds me very much of houses I saw in West Los Angeles.
