Anthony Albanese says the entry fee for credibility on climate change is acknowledging the challenge but Pacific leaders say they're being short-changed by Australia.
The warming climate and rising sea levels which pose an existential threat to smaller Pacific Islands nations are key topics being discussed by more than 50 leaders at the Commonwealth Heads of Government Meeting in Samoa.
Mr Albanese arrived with King Charles and Queen Camilla in the island's capital Apia on Thursday, with the prime minister set to attend a leaders meeting and hold face-to-face talks with UK counterpart Keir Starmer for the first time.
