After a disappointing visit to Carselding bunnings I went to lawnton bunnings where I almost cried because they have everything in stock and the staff are good.
I have decided on 90x90mm x 4 bolted together to make a 180mm post. I wont worry about cables because it will not have power all the time as my battery is nice and portable. Its about $60 in wood + the rest of the stuff and should make a solid design.
Also due to the heavy rain of the last few days the ground has soaked in about 50cm making the hole digging very easy even for a unfit bugger like my self. I'll post pictures shortly as I go along.
The cost so far is $50 for a post hole pincer, I needed 1 anyway so its ok.
