The Micronesian nation finished seventh in the men's division one competition in 2014, despite only losing one of their five matches.
Vice-Captain Kenneth Oppenheimer made his international debut at that event and believes Nauru were and are better than their final placing suggests.
"I don't think the way they did the ladder then was very fair because we only lost one game against the Irish," he said.
"I don't think we're actually the (seventh) in the world. We’re a bit higher than that, I do believe so."
