The Tank Cottage lies to the south of the house, sheltered by a large walnut tree and possibly the oldest olive tree in Australia (at least according to local legend). The tank cottage was built by convicts out of hand-made bricks and, as its name suggests, was originally, in part, a water tank, but it also contained a laundry and ostlers accommodation.
Upstairs in the attic are three single beds, which can be rearranged with two of the beds combined as a king bed. The screened-off downstairs sleeping area contains one king bed which can be split in to two singles. Downstairs, it contains a bathroom and kitchenette and has a slow combustion fireplace in the lounge hearth.
