T2:5/6 Taunton Town Centre

What’s the meaning of these curious disks seen at various points on the cycle routes that form part of the UK’s National Cycle Network?

This disk is (I think) number 5 in the T2 series. T2 is the set of six disks with the theme of “the continents”.

I suppose this represents Australia — what looks like a kangaroo hopping about beneath a sunny sky, with the outline of Ayers Rock/Uluru in the middle.
