Perth Station Art Series: Elizabeth Quay Jetty
Series Information
One of the things I love about commuting by public transport is that you get to see things out the window that you otherwise would not have noticed when using other modes of transportation. However, when you're in the rush of the commute, you can often lose perspective of your surroundings.
This series intends to takes a closer look at the public art at stations along Perth's public transport network.
Artwork Information
Four Winds
Penny Bovell (2018)

The artwork takes inspiration from 17th and 18th century etchings by Masters such as Albrecht Durer. The work imagines wind travelling across Elizabeth Quay from all directions, in motion, amidst, around and over the billowing, blue sky coloured canopy.

Cache Information
The final cache is not located nearby to the posted coordinates. You can catch the ferry from the posted coordinates to the final geocache. A return journey will cost you a one zone ticket. Tickets can be purchased on the jetty (or if you are a local, use your Smartrider as it's cheaper). More information on tickets can be found here.
The final cache is a brown painted bison tube hanging in a tree.
As is always the case, please make sure that you return the cache as found, to ensure that future geocachers enjoy the same experience that you do.
Don't forget to bring your own writing implement, as one is not provided.
