The cache is a Bison tube hidden amongs the woolly jumpers along this section of the trail, all the posts between the 2 road crossings have their own wooly jumpers knitted and attached, one of the weirdest fence features I have come across, very quirky.
On our travels we have come across shoe fences, hat fences, hub cap fences, gumboot fences, bra fences, and many more but this is the first woolly post fences I've seen or heard about.
