In 1862 Bray went into partnership with
Samuel Gray, who was one of his brothers-in-law, and they purchased the lease on a large property in the Tweed Region which they named
Upper Walumban (also recorded as
Wollumben and
Walumbin Run) with a total land area of . For this investment Bray moved to the region in 1863, sailing from Sydney to
Ballina, and arriving on 24 June. Bray took a keen interest in the local Aboriginal people and he immediately began to learn the
Yugambeh–Bundjalung languages and was soon able to carry a conversation with people in their own language. In July 1864, to stock the station, Bray became the first man to drove cattle across the
Nightcap Range and, in a letter to his future wife, he described it as "very unpleasant". Throughout the remainder of the 1860s and beyond Bray became increasingly involved on public life in the Tweed and he became a prominent community leader. In 1866 he became the first postmaster when the first post office was established at his home and Gertrude served as the postmistress; it was known as 'Wollumben Post Office'. This appointment made official work that Bray had already been doing as, before the post office opened, Bray had already been organising Aboriginal men to carry mail from up from
Ballina and
Casino and also down from
Queensland. == Later life and death ==
