In 1864, Richardson and his brother were involved in the formation of the Portland Squatting Co., which sought to exploit liberal land regulations in other colonies. They sailed to Western Australia the following year with 1,600 sheep, arriving in
Cossack and later venturing further in the
Pilbara, where they established
Pyramid Station. After a few years, Richardson and his brother bought out their other partners, and expanded their holdings to include
runs along the
Fortescue River. In 1874, Richardson moved to a farming property, the
Lowlands Homestead, in
Serpentine (near
Perth), although he retained (and continued to expand) his property in the
North-West. In 1880, he severed commercial ties with his brother and with several others (including two other future MPs,
William Paterson and
Samuel Elliott) formed the Murray Squatting Company. The company subsequently developed a property in the
Kimberley, which became known as
Yeeda Station; they later acquired additional properties in the same region. ==Politics==
