Trees
The Australian baobab, or bottle, tree, is hard to miss. Its oddly disproportionate trunk can be as much as 10 feet around. The pith and seeds of its oval fruits are edible both raw and roasted, and its roots and leaves are traditional remedies for digestive problems.
Identify the native almond tree of western Australia by its feathery clusters of silver green leaves. The tree's fruit is edible.
The Pindan walnut tree grows to about 15 feet. Simply gather its dropped nuts and crush their shells between a pair of stones to get the nutmeats.
The green fruit of the 30-foot wild mango or green plum tree ripens in mid-winter and can be eaten raw.

Fruits
Bush tomato plant
Akudjura, known both as the bush tomato and bush raisin, grows in the arid areas of western Australia. It's a shrub with fuzzy silver-green leaves bearing small purple fruits that resemble raisins when dried in the sun. The ripe fruit tastes similar to tomatoes, becoming sweeter as it dries.
The kangaroo apple grows on shrubs of up to 6 feet in height, with dark leaves, mauve flowers and purple stems. The fruit itself is a small orange berry. While it's edible, it's not particularly tasty.
