GeoScience Australia

Geoscience Australia’s Geological TimeWalk allows visitors to cover 4.6 billion years of the Earth’s geological history in an easy 1km walk.


Opened by the Minister for Resources, Energy and Tourism, Martin Ferguson in November 2009, the TimeWalk highlights the vast ages of most of Australia’s mineral resources, dating back some 1200 million years ago.

Screenmakers manufactured and installed 19 x A3 pedestal signs, 42 granite markers and one large pedestal sign to identify the GeoSciences TimeWalk track. The granite markers count down from the time of formation of earth to present day. The small A3 pedestal signs explain the geological formation for a particular period of time.

The opening plaque was acid etched out of 3mm brushed stainless steel, then filled in black and given a clear protective coating. It was installed with four silver anodised stand-offs to the concrete pad at the start of the walk.

The 19 interpretive signs marking the walk were digital flatbed printed direct to the rear side of 5mm Hi Impact acrylic, and mounted within our slimline aluminium sign frame extrusions. The lean-back legs were made from aluminium channel, which is standard for Screenmakers’ range of Park signage. The complete sign unit was powder-coated in satin black.


The extra-long sign was made the same way as the smaller A3 signs, and marks the end of the walk. It summarises the information on all the other signs.
