Australia Faces Roading Crisis as Bitumen Shortage Deepens
A conflict-driven supply crunch through the Strait of Hormuz has doubled bitumen prices and stranded tankers, forcing Australia to adopt a harder, lower-grade substitute that will reduce road life by a third.
Australia is running critically low on bitumen, a crude oil byproduct essential for road surfacing. The shortage, caused by the conflict in the Middle East disrupting supply through the Strait of Hormuz, has seen prices double and left tankers stranded at sea.
A Temporary Fix with Long-Term Costs
The Australian Flexible Pavement Association (AfPA) has secured an alternative supply from Venezuela and the US. This substitute, known as Class 240 (C240), is harder and more viscous than the standard Class 170 (C170) bitumen currently used in 95% of Australian roads.
While the move keeps the industry moving, the National Transport Research Organisation (NTRO) warns it will reduce road service life by approximately 30%—from the usual 10 years down to about seven years.
Supply Lines Under Strain
Australia typically imports its bitumen from Asian refineries in Singapore, Thailand, and South Korea which rely on Middle Eastern crude. The situation is compounded by a recent fire at Viva Energy's Geelong refinery—Australia's only domestic producer, which supplies about 20% of national demand.
- Critical Timeline: The NTRO estimates Australia has just 30 days of bitumen supply remaining.
- Secured Stock: Alternative supplies from Venezuela and the US are confirmed until early June.
- State Response: Queensland has become the first jurisdiction to approve the temporary use of C240 bitumen; other states are expected to follow.
Industry and Government Reactions
Tony Aloisio, AfPA CEO, stated there is no significant bitumen reserve in Australia, calling the shift to C240 "a temporary fix to keep the industry moving."
Michael Caltabiano, NTRO CEO, warned that without a resolution in the next 30–60 days, Australia would face "major problems."
Sean Holden, Flinders Ranges Council CEO, expressed concern over increased maintenance costs for local councils, who will bear the brunt of shorter road lifespans.
A spokesperson for Transport Minister Catherine King said the government is "working with states and industry on the supply chain impact."
A Glimmer of Hope
The NTRO noted that Australia is entering its cooler months, when roadwork naturally slows, providing some buffer. The industry is hoping the oil crisis will resolve by September or October.
