Queensland has the highest rate of mortgage payment defaults in Australia.
Fitch ratings agency says there has been a drop in defaults nationally, partly due to stable interest rates.
But Queensland is the worst performing state.
''Interest rates have played a factor, property prices have also featured, particularly in some regions, as Gold Coast properties are taking longer to sell,'' said spokeswoman Natasha Vojvodic.
''Also regional unemployment. Even though the national unemployment rate is at 5.2%, some regions have been experiencing higher unemployment.''
