The coronavirus is choking supply chains, leaving Australia's fuel supply "seriously vulnerable", Centre Alliance Senator Rex Patrick says. Energy Minister Angus Taylor this week announced he signed an agreement with the United States which would see it grant Australia access to emergency oil supplies in the event of a major global disruption. Currently Australia has between 25 to 30 days of fuel reserves on shore, but Senator Patrick warned it was not enough, especially in times of global uncertainty. “We are supposed to have 90 (days),” Mr Patrick said. “We also don’t know what this agreement is, if it’s a treaty, what threshold causes the US to start supplying us oil, we don’t know how it gets here. “In a situation like this where we have supply chain issues like this with coronavirus, people can have the best will in the world to get us supplies and not be able to. We are seriously vulnerable in respect to our fuel reserves.”
