Local context that affects the install: == Transport ==
Ferntree Gully has a railway station located on Station Street, near the shopping district, which was previously known as Lower Ferntree Gully, followed by Fern Tree Gully, having been changed to the latter on 29 February 1972. Older housing means more openings and a longer sensor list. Boronia, Knoxfield, Lysterfield and Rowville and Ferntree Gully form one continuous area for us rather than a list of separate suburbs.
Boronia is our base, roughly 2.7 kilometres south of Ferntree Gully. Short distances like that are why we can commit to a time and keep it. Something else that shows up in the housing here: The area became more accessible to visitors with the arrival of a railway line extension from Ringwood, completed in 1889.
There is more to the local history than that: Officially opened on 17 October 1959 as the Mountain Gate Estate, it was marketed as the "town of a thousand homes" incorporating a modern car-oriented shopping centre and public parkland.
