A visit by Australia's prime minister to Vanuatu and Fiji this week is the first by an Australian prime minister in decades. The trip follows the Australian government's Pacific "Step Up" announced just over a year ago and observers say it's an effort to show Australia is taking the Pacific seriously. Mr Morrison is scheduled to arrive in the Vanuatu capital Port Vila today - in what's also being seen as a push to stem China's growing influence in the region. RNZ Pacific's Sally Round filed this report.
