Queensland remains the worst-performing state in mortgage performance, according to a leading measure of mortgage arrears.

New figures from Fitch Ratings show that the rate of mortgage delinquency in the Sunshine State surpasses the nation-wide average and is up 1.42% on September 2011 figures.

Fitch Ratings reported that the current rate of mortgage delinquency – the proportion of mortgages that are more than 30 days in arrears – is at 1.86%.

The researcher also found that regions south of Brisbane, such as Ipswich, Logan and the Gold Coast are among the worst-performing in Australia.

Rates in Brisbane, on the other hand, are below the national average.
