When did the white settlers arrive in Australia and in Western Australia in particular?

The First Fleet arrived in Australia on 26 January 1788. In 1829, Captain Charles Fremantle was sent to take formal possession of the remainder of New Holland which had not already been claimed for Britain under the territory of New South Wales. In May of that year, Captain Fremantle raised the Union Jack on the south head of the Swan River, thus claiming the territory for Britain. The colony of Western Australia was proclaimed on 8 June 1829, and two months later, Perth was also founded.
