There is still no date set for the reopening of a Mount Keira walking track that has been closed since September.
Part of the northern section of the popular Mount Keira ring track was closed by National Parks and Wildlife Services (NPWS) after a large rock fall on September 18.
The section closed extends west from the Mount Pleasant track to the stairs leading up to Queen Elizabeth Drive.
All areas above Mount Keira ring track to the summit, except for the Dave Walsh track and the rock-climbing area on the western face of the mountain, are also closed to the public.
A spokeswoman from the Office of Environment and Heritage said a preliminary risk assessment was carried out shortly after the track closed and the geotechnical advice given was to keep the track closed
"The advice included monitoring the track for further falls for 12 months," she said.
At this stage the track would be closed "indefinitely" for the safety of park users, but NPWS is looking into options to reopen it at some stage.
The spokeswoman said rock falls at Mount Keira could be a regular occurrence.
"The geology, steep terrain and high rainfall of the escarpment make it susceptible to rock falls, landslides and extreme erosion," she said.
"These are ongoing natural processes that led to the creation of the Mount Keira escarpment."
The closure does not directly relate to Mount Keira Road, reopened in August last year after being closed in December 2012.
"The closure of Mount Keira Road was due to a fall on the other side of the mountain," the spokeswoman said.
