Online bank only allows 6 characters in passwords

So I'm interested in what this Subreddit community thinks about my bank - a major Australian bank - and its lax security logon password policies:
A quote from them: "...We believe that 6 characters is an appropriate length to protect and authenticate your online activity."

I find it incredulous that they won't upgrade it to even allow for other characters to be used, only upper/lower case is allowed!
