From Glen Clifford's Notes on the History of Yallum Park, Penola, South Australia:
Yallum, originally 115 sq. miles, was occupied by Thomas, Josiah and Solomon Austin about 1840, they built a house which is still standing.
They sold to Thomas Allan and Henry Edmund Wells in 1856.
They sold to John Riddoch in 1861. He built another house in 1863 and laid out a garden with many rare trees..... In 1878 Mr. Riddoch decided to build the two-storey house ....[which] was completely finished in the first week of January 1880.
In 1914 my late parents (Mr. and Mrs. W. A. Clifford) purchased the homestead.
