In April 1980 the Saitama Prefecture Assembly delegation to southeast asia and Oceania visited Queensland. This served as the beginning of a new relationship, and in October 1984, Saitama Prefecture and the State of Queensland signed a sister state agreement.
Queensland is located in northeastern Australia. Its Great Barrier Reef, the largest coral reef in the world, and resort destinations such as Cairns and the Gold Coast are famous around the globe. The major products in Queensland are sugar and beef. The Saitama Children’s Zoo in Higashimatsuyama feature koalas and kangaroos that were presented by Queensland as a symbol of the sister-state friendship.
