Project Description

The Central Arnhem Road is a 710-kilometre road connecting Katherine via the Stuart Highway to Nhulunbuy. The route links Nhulunbuy to the National Network, services a large number of Indigenous communities and is a key tourism drive and freight route for the mining and pastoral industries.

The Central Arnhem Road Upgrade will involve sealing, reconstructing, widening, and flood immunity improvements to priority sections of the route to a fit-for-purpose standard.


The Central Arnhem Road Upgrade is expected to deliver the following benefits across the route:

Improved Freight Efficiency, Connectivity and Travel Time:

  • improved travel times along the corridor
  • improved flood immunity along the corridor
  • improved access to remote communities

Increased Safety:

  • provide safer overtaking opportunities
  • reduce crash frequencies
  • increase weight and height limit for heavy vehicles

Support Regional and Local Economic Development:

  • support inter-regional connections to and from Nhulunbuy and Katherine
  • support the growth of rural populations and the agricultural and tourism industries


The Australian Government has committed up to $180 million towards this $225 million project.
