While NSW is chasing a 70 per cent double-dose vaccination target, Lord Howe Island off the coast of Port Macquarie has hit about 95 per cent.
The majority of the 400 residents who live on the island, which has not had a single case of COVID-19 since the pandemic began, have had two shots of the Pfizer vaccine.
"People here were very enthusiastic about being vaccinated so we can move back towards normality because having guests here is our primary industry," the island's doctor Dr San Clarke said.
Dr Clarke said the decision was made to only send the Pfizer vaccine to the island because of the logistics of getting it there and appropriate for the greatest number of people, given there are pregnant woman on the island.
Dr Clarke said there were a few people that live on the island, through generations, that were unwilling to get the vaccine at this stage.
"They're only small groups of people, so of course we're hopeful that they'll benefit from herd immunity that the rest of us can provide."
Lord Howe should begin to receive visitors again later in the year.
