The checkout screen appears to be very rigid.

Is is at all possible to configure the fields or at the very least, their labels?

Eg. ZIP should be PostCode in Australia - I have the EN(AU) translation applied to my database but obviously this isn't having an effect.

Also enabling b2b, adds the Company and VAT fields. VAT should be GST for Australia. I would prefer to just not have the VAT field at all.
