In December 1850 he arrived in Western Australia on board the Mary, obtaining employment in the firm of George Shenton Sr.
Between 1855 and 1857 he worked for Robert Habgood, before returning to Shenton's employment as manager of his Geraldton business.
In 1872, he ran the Western Australian Legislative Council seat of Greenough election campaign for his friend George Shenton Jr, who was absent from the colony at the time.
In July 1873, the Supreme Court upheld Gray's complaint, finding that Crowther's actions might have induced electors to vote for Shenton.
No blame was attached to Shenton, but the election was declared void and a new by-election ordered for 29 June 1873.
