'Herald Sun' this morning is highlighting comments by energy analyst Saul Kavonic that given the closure of the Strait of Hormuz, by September if it remains closed Australia has the risk of 'two to three times more likely than (previously in) March/April', having some form of demand management or rationing.
Of course, upping the price is a form of 'demand management'.
Whether this would also affect airlines remains to be seen, but overall Australia imports c.90 per cent of its fuel across the three major categories of petrol, diesel and JetA1. Despite the Prime Minister's complacency, we are vulnerable.
It's hard to see the Iran v Israel/USA war ending tomorrow. Iran seems determined to control the Strait, and there's further risk (in the Red Sea?) from those Houthis.
