[1] His brother John Harris Browne and sister Anna (1812-1873) arrived in 1840 and together they ran a leasehold property at Lyndoch, then Booboorowie, steadily increasing their stockholding.

Apart from huge tracts of land they leased or squatted on, they purchased significant properties: Buckland Park in 1856, "Moorak" at Mount Gambier in 1862 and Booboorowie in 1863.

From 1863 Browne lived with his family at his estate, Moorak, Mount Gambier, where he was a respected pioneer and contributed the land for, and around half the cost of building Christ Church in that city.
