Toohey Mountain is a medium sized mountain at the eastern side of the City of Brisbane's suburb of Moorooka. The rise was named after James Toohey, an Irish born Sydneysider who made his wealth in the California gold rush, before settling in the newly formed state of Queensland. To the north of the mountain is Tarragindi Hill and Wellers Hill.Grass Tree Ridge was the name given to the tall and long ridge that extends through parts of Tarragindi, Salisbury and Nathan, towards Sunnybank. Most of the mountain is included in the Toohey Forest Conservation Park.It features many walking tracks, some of which link up with the nearby Mount Gravatt, the southside's tallest mountain and Griffith University campus in Nathan.Toohey Mountain is the site of two small reservoirs. Norman Creek and Bulimba Creek are two creeks which drain the slopes of the mountain.Also of note, there is an old Channel 7 rebroadcasting tower located on the Melaleuca Walking Track (about 200 m-300 m from the Madang St entrance to the Fimbriata Walking Track) which although discontinued from service for many decades has recently been restored to service as a community wireless access point by the Brisbane Mesh, a community wireless group.
