The gap between the worst and best performing mortgage states is now at its tightest since 2004.
According to new data from Fitch Ratings, the difference between the worst and best performing states is now only 29 basis points, with mortgage arrears sitting in the 1.29 to 1.58 per cent range.
New South Wales and Queensland were the worst performing states in terms of delinquency, with both areas recording an arrears rate of 1.58 per cent.
Nelson Bay in New South Wales remained the worst performing postcode, with a 30-day delinquency rate of 6.6 per cent.
The average delinquency rate across Australia increased to 1.45 per cent, up from 1.2 per cent at the end of September.
Fitch Ratings' James Zanesi said Christmas spending and the increasing cost of living may have caused the rise.
