One of the curious things about koalas is the fact that they hug trees. After observing a group of koalas during hot weather, scientists say they have worked out why. Apparently, trunks of certain trees can be more than 5°C cooler than the surrounding air in extreme conditions. Incredibly, access to these trees can save about half the water a koala would need to keep cool on a hot day.

This year’s Proof Issue from the Australian Koala gold proof coin series portrays a koala edging along a tree branch – maybe in search of a cool spot where it can take refuge from Australia’s intense summer sun!

Extremely Limited

The 2016 series includes 2oz and 1oz coins struck in superb high relief to extremely limited mintages of 150 and 500 respectively. The series also includes rare 1/4oz and 1/10oz versions, meticulously-crafted with the same koala design.
