On Tuesday, the Reserve Bank of Australia (RBA) raised interest rates by 0.5 of a percentage point, taking the cash rate target to 2.35 per cent.
It wasn't until Friday afternoon that the National Australia Bank (NAB) and ANZ announced they were passing on the rise in full to mortgage holders.
By Friday evening, Commonwealth Bank followed suit but many other banks were yet to say if they'd raise their rates or not.
