I avoid them all, there are plenty of alternatives to thieving banks… you cannot fight them because they will use your money to ruin you legally.
Of the big four, avoid at all costs the Commonwealth and ANZ (the worst part of ANZ is the NZ bit). They are ruthless and became worse after Rudd needlessly guaranteed their profits.
Now that the slow-down in house prices is underway we will see the worst of the worst that banks can stoop to.
The farmers’ suffering during the drought has been exacerbated by the banks’ dirty system of resumption of property and house owners will suffer the same fate when prices fall to a point where banks believe their equity is at risk.
If you have to borrow, please avoid banks, there are heaps of more moral alternatives.
