Formal gardens were initially developed in 1910, primarily for the purpose of providing functional spaces for Vice-Regal garden parties and fund-raising events. Generally the selection of plant material in these garden areas was exotic, mostly ornamental and some native trees. Surrounding the gardens was the original bushland that covered about 70% of the entire grounds. In comparison to the formal gardens, the bushland received very little attention except for the successive clearing of the understorey plants and later of sapling and shrub regrowth. In 1928 "woodland walks" were created by Governor Sir John and Lady Goodwin through the bushland behind Government House. Paths were created, foot bridges constructed and various plants introduced, such as jacarandas, wattles and poinsettias.
