I haven't looked into it too much, to be honest. I suppose as the structure meets council development rules, it should just be considered a part of the property and fall under home building insurance. A past policy of mine actually specified covering radio towers and masts by default in the PDS, but my current policy doesn't mention it.

The hole is 1.8m deep x 600mm round/wide. If you have clay soil it only needs to be 450mm wide.

@@VK5IR Cheers. Mines sandy so 600 wide i'll need to go.
