Commemorating the birthplace of the Australian Labor Party, the Tree of Knowledge is a multi-faceted memorial sheltering the preserved trunk of the original tree. The memorial dominates the main street of Barcaldine. The Australian Labor Party was born out of the 1891 Shearer’s Strike and crucial to this area. It was a time of unrest and standing up for a fair go. A time that also spawned the song Waltzing Matilda. The size of the Tree of Knowledge is a surprise. It is huge and most impressive, it is made up of 3500 sharpened lengths of timber hanging down on wires. As the warm Western Queensland breeze blows it becomes a giant walk through wind chime. What is that saying about politicians? Something about hot air?
