"lol re hiring a post hole digger, not so easy when one lives in the bush but yeah we will be asking around to see if someone has one we can borrow when the times comes "

The bush is where you are most likely to find one. You don't think all the holes for corner fence posts (the strainers)

were dug manually do you ?

Most farmers have one, even a manual thing that looks like a very big cork screw, turned manually.

Still hard work but it beats using a spade !
