Cheers Ed. We have similar type of regs here, just laxer - it's QLD
. If I keep it under 10sqm and under 2400mm high I don't need to even make an application. Larger than that and I can probably get approval easy but have to pay few fees, get some full engineering drawings done and pay for an inspector, not too hard. I figured since no one spot here is perfect I would put a "small" one in and either go bigger later or put another small one in with other better views.
