Australia and Vietnam have signed a reciprocal agreement allowing Australia to export plums and Australia to import passion fruit. This comes as Vietnam's plum imports have seen a 132% increase, presenting a significant market opportunity for Australian growers. The main plum-producing regions in Australia are Western Australia, South Australia, Queensland, and New South Wales, with Victoria being the largest producer. Negotiations are already underway for the export of Australian blueberries and the import of Vietnamese pomelos.
