Bankwest has above-average dispute levels in many separate categories of the Financial Ombudsman Service's 2014/15 dispute league table.
For every 100,000 home loan customers, the median number of disputes between lenders and their borrowers was 40.8 in 2014/15.
Bank of Queensland copped 90 disputes per 100,000 borrowers last year. Rams had 68 and Bankwest had 72 per 100,000.
