Explanation:
Queensland is roughly bisected by the Tropic of Capricorn, and since the great bulk of the population lives on or near the coast or periodically flooded rivers where the heat tends to be humid in summer, a characteristic style of housing known as the Queenslander has been developed, which passively addresses the warm-hot climate as best any housing could do.
This house is built almost entirely of timber, having its frame, wall cladding (both exterior and interior), floors and ceiling being all timber. The roof is corrugated iron (more recently a longer-lasting corrugated steel known commercially as Colourbond). It will be raised off the ground on brick stumps (or brick footings with timber stumps) by up to three metres to elevate it above flooding, its picket skirts shading an area which can be used for vehicle and boat storage, and where the washing may be hung during wet weather, and kids can play out of the sun (as long as they avoid spiders and the more venomous snakes). It will have a set of timber stairs (sometimes two, sideways) leading up to a central front door.
The timber stores little heat. Because these are mostly built fairly close to the coast, there is usually insufficient benefit of using the latent heat of masonry to keep the house cool, since nights are warm, too.
Inside, the ceilings are high, with preferably a high louvred vault to allow the hottest air to escape. There are wide eaves, indeed usually at least two sides are sheltered by a deep verandah (often used as a screened "sleep out"). Windows are timber casements and often made of obscure glass, and screened to let breezes through. They may be decorated with timber fretwork, both outside and in.
They are not perfect, painting them is a huge chore! It is important to inspect them frequently to avert termite infestations (relatively easy since the underside is inspectable). But they are eminently portable (one episode of Grand Designs Australia showed the homeowners interviewed inside the house as it was jacked up to insert another level of house underneath), and with decent maintenance will last over a century, sometimes having been sliced in two and trucked to live in a different town from where they were originally built
