The size of the average loan in Queensland is now $513,000, a rise of 25 per cent in a year, according to the ABS.

And one of the causes of the sharp drop in new home buyer commitments is likely to be the flood of money into investor housing in Queensland.

The data shows investors started piling into the Queensland market in May 2020 when the total amount lent in a month was $500 million. By November 2021 it was $2.2 billion.

Nationally, investor lending rose 3.8 per cent reaching a new all-time high of $10.1 billion.

While the first home buyer market has fallen dramatically over the year it was still ahead of where it was for a period stretching from 2012 to 2018.

ABS head of finance and wealth, Katherine Keenan said investor lending had grown for the past 13 months and accounted for about one third of the value of new housing loan commitments in November 2021.

 The previous investor lending peak in April 2015 accounted for 46 per cent of new housing loan commitments.

Increases in investor loan commitments were strongest in New South Wales (up 7.8 per cent), Queensland (up 5 per cent) and Victoria (up 3.6 per cent). All states rose, while both territories fell.

The ABS said new lending Australia-wide for housing rebounded in November with an increase of 6.3 per cent to $31.4 billion following three months of falls.

The value of all new loan commitments for owner-occupier housing rebounded 7.6 per cent in November. The rise was the first since May 2021 and the largest since January 2021.

At the national level, the average loan size for owner-occupier dwellings rose to an all-time high of $596,000. Average loan sizes reached new highs in all states and territories except Western Australia.

The number of new loan commitments to owner-occupier first home buyers rose 1.9 per cent in November 2021 breaking the decline since January 2021. The number of these commitments was 17.4 per cent lower compared to a year ago.
