- Is this level of fine appropriate to deter a company the size of Westpac from multiple infridgement activities?

Oliver,

Whether the fine is $8500 or $850 million, you can be sure that Westpac won't be passing this cost onto its shareholders. You know who normally has to pay for bank's mistakes.

Steel Mann,

Your words read true to me.
