The Waddi Tree, open from April to September, houses a souvenir shop and art gallery. The Waddi Tree is so named as Waddi trees are only found in Boulia and Birdsville and typify the outback. The Pitta Pitta art gallery features unique bark paintings from local Aborigines. Why the name Pitta Pitta? Pitta Pitta was an Aboriginal language, now extinct, spoken around Boulia and with a number of very talented artists in the area, the Spilsbury’s wish to share their work with everyone.
