Linking Australian employers and Tongan workers

Labour mobility is a key driver of growth and will make an important contribution to Tonga’s economic recovery from the Hunga Tonga-Hunga Ha’apai volcanic eruption and COVID-19. We are working closely with the Tongan Government to enable an efficient, safe and economical resumption of circular labour mobility.
