Australian grey geese have fast wings and powerful flight speeds, but they fly with little formation and order. It is a completely vegetarian bird, which takes various grasses, especially gramineous plants, such as flat Miscanthus and weeds, as food, and locally uses crops as food, which is considered to be an agricultural pest.

Australian grey geese mostly live in shrub areas during breeding period. The non-breeding season is in the open coastal grassland. Live in pairs. Return to the breeding grounds in about February, and start nesting in late May or early June, with grass on the ground. The eggs are laid from the end of June to the middle of July, and each clutch produces 4-5 eggs, which are white and hatched by the female goose. When she leaves the nest, the eggs are covered with grass. The incubation period is about 35 days. The chicks live with their parents for about a month and a half, and those who leave their parents form their own groups, sometimes up to 200.
