Australian PlantBank, Seed vault and research facility in Mount Annan, Australia

The Australian PlantBank is a seed bank in the Australian Botanic Gardens, Mount Annan, and part of the Millennium Seed Bank Project. Its building, designed by BVN, opened on 11 October 2013 and received the Australian Institute of Architects' National Award for Public Architecture in 2014. It holds seeds of over 5,000 plant species in temperature-controlled storage, alongside laboratories and a public viewing area.

The facility was founded in 1986 as a conservation center and evolved into a modern research institution, with its new main building opening in 2013. This expansion marked a major step in systematic preservation of Australian plant species.

The name PlantBank echoes the site's role as a working store of wild-collected seed, part of the Millennium Seed Bank Project. The building opened on 11 October 2013, when Professor Marie Bashir cut the ribbon before Robyn Parker, Minister for Environment and Heritage, and Ken Boundy, chair of the Royal Botanic Gardens and Domain Trust. Visitors can watch bank work through a public viewing area with interactive displays.

Visitors should know that the facility often requires advance notice, as access is controlled to protect the collections. It is helpful to check current visiting conditions in advance.

The building designed by BVN won the National Award for Public Architecture from the Australian Institute of Architects in 2014, a year after it opened. The opening ceremony on 11 October 2013 was led by Her Excellency Professor Marie Bashir, with Robyn Parker MP and Ken Boundy attending.
