The land around the locality of Clemton Park was part of the 500 acre land grant to Hannah Laycock in 1804. To see just how far Hannah's initial land grant stretches, take a trip south to Heavy Heart and read more about her in the description there.
The suburb of Clemton Park is named after Frederick Moore Clements (1859-1920), who was a pharmacist and successful businessman who produced the well known Clements Tonic. Canterbury Council approved the name of Clemton Park in 1925, and it was used as the name of the locality around where Clements had owned land. The name was never officially gazetted as a suburb with defined boundaries but the locals still used the name, putting in an application to the Geographical Names Board in 2000 to finally have the suburb recognised and defined.
Prior to residential zoning, the electrical appliance manufacturer Sunbeam owned the land from 1951 to 2002 where the factories produced the iconic Victa Lawnmower along with toasters and kettles. Before this, the block was Mackinders Market Garden farming potatoes, beetroot, carrots, pumpkin and squashes. Streets in the precinct bare the names of Victa, Sunbeam and Mackinder.
The cache is named after The Sunnyboys 1981 classic, Alone With You, written by lead singer-guitarist, Jeremy Oxley (listen to this live version from 1998 to hear the song). There's nothing particularly difficult about the actual hide, the difficulty comes from avoiding the eyes of potentially dozens of residential and park-enjoying muggles, meaning you'll never be alone.
