Nauru President Baron Waqa will hold talks on renewable energy and immigration policy when he visits Australia later this week.
Mr Waqa will be the first Nauru president to visit Australia for more than two decades.
During the four-day visit, he'll meet Prime Minister Malcolm Turnbull and NSW Governor David Hurley in Sydney.
In Canberra, he'll tour the Mount Majura Solar Farm and discuss renewable energy with senior management, visit the Australian War Memorial to lay a wreath, and be officially welcomed at Government House by Governor-General Sir Peter Cosgrove.
The program will also include meetings with several senior ministers and opposition MPs and the Governor of Queensland Paul de Jersey.
