There are many varieties of spiders in Australia, which thrive in different conditions. Some spider varieties that are commonly found inside homes have adapted to the conditions indoors and can live in a less humid atmosphere and with less food available. Some can even survive for months on end without food or water! Spiders that live outdoors prefer warm and damp surroundings, in which insects are their preferred source of food.
