New lending statistics have revealed big gains for Bank of China but only minimal growth for Bank of Sydney.
Bank of China had $672 million of owner-occupier and investor loans on its books as of 30 September 2014, according to APRA data.
That marked an 18.5 per cent increase on the previous year.
Bank of China's strong growth was driven by a 23.9 per cent jump in the investor book to $405 million.
However, the portfolio of owner-occupier loans fell 1.1 per cent to $267 million.
Bank of Sydney ended September with $333 million of owner-occupier and investor loans.
Owner-occupier loans remained steady at $111 million, while investor loans climbed 1.4 per cent to $222 million.
