The Centenary Bonsai Prize 2023

The Centenary Bonsai Prize from the National Bonsai & Penjing Collection of Australia (NBPCA) celebrates the centenary of Canberra as the nation’s capital (2013) and each decade after that until the bicentennial in 2113.

The NBPCA invites bonsai artists working in Australia to submit photographs of their bonsai for the Centenary Bonsai Prize. Entry to this competition is free of charge.

The winner will receive:

  • a cheque for $6000,
  • a plaque, which they can keep for one year before returning it to the Collection, and
  • a framed certificate of the award to keep.

The Centenary Prize is an acquisition prize and the winning tree becomes part of the National Bonsai & Penjing Collection of Australia (NBPCA).
