Brothers Thomas and Alexander Milsop were attracted to Australia in 1852 by gold discoveries in Victoria. They failed to make their fortunes there or in New Zealand. They then struck it rich on the Kurrajong goldfield near Forbes in NSW.
The Milsop brothers moved to Wollongong Rd in 1881, purchasing six acres each and erecting two identical houses, Belmont and Fairview. Alexander became the first Mayor of Hurstville.
I don't know anything about their current use, but supect they are either boarding houses, halfway houses or some kind of rehabilitation centres.
