He was eventually released, subsequently convicted again of a similar offence, and served gaol time in the goldfields in what would later be the colony of Victoria.
After he was again released, Groom eventually found himself on the Darling Downs in Queensland, where, despite whispers about his chequered past, he became one of the leading members of society.
During his first term as Mayor he successfully led his council to petition the colonial government for land for a town hall, a municipal market and the original site for Queens Park.
In 1862 Groom was elected to the Queensland Legislative Assembly in the electoral district of Toowoomba with a majority of 21 votes.
Unfortunately, he was given little time to enjoy the crowning glory of his political career, as he died on 8 August of the same year at the first Commonwealth Parliament meeting in Melbourne.
