David Keith Ballow was born in October 1804 at Montrose, Scotland, the eldest son of John Ballow. He studied at the University of Edinburgh.

He immigrated to Sydney in 1834. On 21 October 1837, in Sydney, he married Catherine Campbell, the youngest daughter of Captain D. McArthur, of the 2nd Royal Veteran Battalion. In December 1837, Dr Ballow was appointed Assistant Colonial Surgeon in Sydney.

Medical career in Brisbane
In March 1838, he was placed in charge of the Government Hospital in Brisbane. Ballow and his wife arrived in Brisbane as it transitioned from being a penal colony to a free settlement. He later become the Resident Surgeon of the Moreton Bay General Hospital. He was also the coroner for the Brisbane district and the visiting surgeon of the gaol.

On 8 August 1850, the immigrant ship Emigrant arrived in Moreton Bay with typhus on board. The ship was quarantined at Dunwich on Stradbroke Island away from Brisbane. Forty people on the ship died, including the ship's surgeon Dr George Mitchell. Initially Dr Mallon came from Brisbane to care for the quarantined patients at Dunwich but he too contracted the infection. Dr Ballow took his place and also contracted the disease. Dr Kearsey Cannan took charge after Dr Ballow's death. He put his tent on Bird Island, visiting his patients as required from there and managed to avoid catching the disease.
