Papua New Guinea has ranked 144th out of a list of 175 countries on this year's Transparency International Corruption Perception index.
It's the only Pacific Island nation to make the list - Fiji has not featured since the 2006 military coup because three independent assessments are needed to qualify.
Denmark and New Zealand topped the chart, while Somalia, Afghanistan, and North Korea tied for last place.
Transparency International PNG Spokesperson, Lawrence Stephens, says PNG received the same score last year and while it's frustrating to lie near the bottom of the table, positive things are happening.
"Bit by bit people are more uptight about what they're seeing, the social media here are very active, there are more comments being made all the time and gradually we hope the leaders are seeing that corrupt behaviour is not acceptable."
Lawrence Stephens says there's still some confusion particularly in rural areas about the exact meaning of corruption.
