I know an aircraft owner that lives in a remote location, he owns and sell accomodation (holidays) at the remote location and then offers to pick the guests up from civilisation and fly them out and back for free. The same guy owns a shop at the remote location and he regulary takes his own stock out to his own shop(several flights each week) . no doubt some of the items he transports are pre-ordered but at the time of transport the goods are his own.
CASA has been trying to stop this pilot for years and nail him but have been unable to get enough/any evidence to do him over, the airworthiness inspectors use terms like "what he is doing is not illegal but is not within the spirit of the rules"
