Over 2000-2005 she created Call Signs, a project developed over thirteen exhibitions which used sound, maps and painting to create an imaginary sense of space and distance.

A call sign is a term used in Morse code and the sound objects in the work were mainly simple electronic circuits for Morse code indicators constructed using needlelace as the main support. The needlelace both insulated the wires and was used to form the objects into miniature landscapes: trees, reeds and flowers within which the components, resistors, LED's, speakers, capacitors etc, formed decorative details. A number of the indicators grouped in an installation give the impression of a Morse code conversation carried out across lonely distances.

In 2008 she received a development grant from the Australia Council's Visual Arts Fund to translate these small works for large-scale installation over 12 months. This period of research resulted in the current project, Homeland.

In Landscape and Memory Simon Schama writes that the appreciation of landscape is the work of layers of personal memories and cultural tradition. Homeland considers the layers Australian tradition, culture and history that inform Australian landscape.
