The Wombeyan caves are just over 1,000km from Bundall on the Gold Coast.
From wikipedia: "Marble is a non-foliated metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Geologists use the term "marble" to refer to metamorphosed limestone; however, stonemasons use the term more broadly to encompass unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material."
In 1915 it was noted that white sacchoroidal marble occurred at Wombeyan in enormous quantities and in 1941 a lease was granted to mine the marble on the western reaches of the reserve. Mining continued under different leases until 1997, when the operations ceased due to environmental concerns for the well-being of the caves and ground water.
It is not defined on when this marble was mined from the site, but the little information sign will give you some more details.
The sculpture here is by May Barrie who was born in Denmark. Her bio states that "May Barrie, esteemed Australian sculptor, has sharpened an ability to draw out sensual abstract forms from craggy rocks and intonate human relationships."
