Australia imports most of it's diesel, gasoline and jet fuel from South Korea and Singapore. So what happens when South Korea and Singapore are not getting enough oil from the Persian Gulf? They stop exports to Australia. Australia used to have 8 refineries 25 years ago. Now there are only 2. Government policies for "climate change" have made it impossible to operate without subsidies. As a result, Australia is entirely unprepared for shortages. Truckers are being stranded in Australia, food deliveries are not happening to grocery stores. The supply chain is breaking down.(Wall Street Mav)
