The straightforward answer to this questions is 1901. Prior to this, Australia was made up of six self-governing colonies; New South Wales, Victoria, South Australia, Queensland, Western Australia and Tasmania. These colonies were ultimately under British rule from the time the First Fleet landed, in 1788, until 1901. On 1 January 1901, federation of the colonies was achieved and the Commonwealth of Australia was proclaimed by Australia's first Governor-General, John Hope, at Centennial Park in Sydney. This gave Australia the right to govern itself.
However, the path to complete independence from Britain took many decades. For further information, see the related question.
