Get involved Become a friend Why become a friend? Jupiter Mosman is the namesake of our company, Jupiter Mosman Housing Company Ltd. It was established on 4 April 1975 under state government legislation, some 30 years after Jupiter Mosman passed away in 1945.

This will take time to set-up. So watch this space over the coming months while we add to the gallery. In the meantime, we have two appeals we hope will interest you: Help build low rental homes Help us Furnish homes
