Australia's energy landscape has drastically changed over recent decades, moving from a self-sufficient producer of oil to a country highly reliant on imports. With domestic oil production plummeting by around 90% since the year 2000, Australia now grapples with the challenges of dwindling local oil fields and a significant reduction in refining capacity. The situation is ironic considering that Australia is one of the world's largest exporters of natural gas and coal.

The history of oil shocks, particularly stemming from Middle Eastern conflicts in the 1970s, serves as a warning for Australia, indicating that the nation should have been better prepared for potential energy crises. As reliance on imported oil increases, the implications for national security and economic stability become even more concerning, as disruptions in the global oil supply chain could leave Australia vulnerable.

With six major refineries closed and no significant plans to boost local production, Australia is at a critical juncture. The capacity for domestic oil production and refining has diminished to levels that could threaten energy security, highlighting a need for strategic investments and policy shifts to mitigate the risks associated with future energy crises.
