6 years after the death of her husband in 1882, Elizabeth Onslow took her children to England. While the children were at school, Elizabeth studied dairy farming and on returning to Camden in 1889 she founded a dairy farming complex, the Camden Vale Milk Co., which eventually merged with the Dairy Farmers' Co-operative Milk Co in 1928. Dairy Farmer's 'gold top' milk, known by its gold foil bottle top, was sourced from Camden Park. The property is still a working dairy farm.
