Australia Post Group has announced an investment of approximately A$500 million (US$324 million) to build an ultra-large parcel processing centre at the former Holden automotive manufacturing plant in Elizabeth, South Australia. The facility represents Australia Post’s biggest-ever investment in the state and will become the largest site in the organisation’s national network when it opens in 2028.
Facility Overview
The new parcel super hub will span 83,000 square metres and serve as the first fully combined Australia Post and StarTrack facility in the company’s history. Equipped with advanced sortation technology, the centre will be capable of processing up to 400,000 parcels per day, effectively doubling the current capacity at the existing Adelaide Airport Parcel Facility.
The site’s scale and automation represent a step change in how parcels move through the South Australian network. By consolidating Australia Post and StarTrack operations under a single roof, the facility is designed to streamline processing workflows, reduce handling times, and improve service reliability for both consumer and business-to-business deliveries.
Strategic Significance
The choice of the former Holden factory site in Elizabeth carries considerable symbolic and practical weight. The Holden plant, which ceased vehicle manufacturing in 2017, was once one of South Australia’s largest employers. Repurposing the site for a major logistics hub signals a broader economic transition for the northern Adelaide corridor, from traditional manufacturing toward modern supply chain infrastructure.
The investment also reinforces Australia Post’s commitment to network capacity ahead of projected demand growth. As the largest facility in the organisation’s national footprint, the Elizabeth hub will serve as a critical node in the interstate parcel network, handling volumes destined for both metropolitan Adelaide and regional South Australia.
E-commerce Driving Investment
The scale of the investment reflects the sustained growth of online retail across Australia, and South Australia in particular. According to Australia Post, approximately 80% of South Australian residents have shopped online in the past year, with the state experiencing consistent year-on-year e-commerce growth. That trajectory shows no signs of slowing, and parcel networks must expand ahead of demand to maintain service standards during peak periods.
Australia’s e-commerce sector has placed increasing pressure on parcel sortation infrastructure in recent years. Facilities designed a decade ago were built for lower volumes and different parcel profiles. The shift toward higher daily throughput, combined with growing consumer expectations around delivery speed, has made investment in next-generation processing centres a strategic necessity for major carriers.
The 2028 opening timeline gives Australia Post a runway to design and commission sortation systems that reflect current best practice in automated parcel handling, while also building in capacity headroom for future volume increases. For South Australian businesses and consumers, the super hub promises faster processing times and improved delivery performance across the state.
The announcement positions Australia Post alongside other major logistics operators investing heavily in automated infrastructure to keep pace with Australia’s evolving retail landscape.
