The former NSW Seedbank was established in 1986[2] and originally collected wild seed for the Gardens.

The former seedbank went through an extensive upgrade in 1999 and ensured that the seeds were of high quality.

The biggest and latest update was in 2013, where the NSW Seedbank turned into the Australian PlantBank.

In 2014 the new building, designed by BVN, received the National Award for Public Architecture from the Australian Institute of Architects.
