An international competition was held for the design of the Memorial, which was won by Liam O'Connor Architects and Planning Consultants, with Ian Rank-Broadley, Sculptor. The project design team consisted of Liam O'Connor (architect), Christopher Barrett (project manager), Alan Baxter & Associates (structural & civil engineers), Christina Godiksen, Robert Rhodes, and Daniel Benson. Liam O'Connor also designed the Commonwealth Memorial Gates on Constitution Hill in London. Ian Rank-Broadley conceived and executed the sculpture of the Memorial. He earlier sculpted the effigy of Queen Elizabeth II which has appeared on coins in the UK and Commonwealth coins since 1998. The letter cutting was done by Richard Kindersley. The design of the Memorial was officially unveiled at the Imperial War Museum, London on 6 April 2005.
