The difference between your interpretation and mine is that I have spoken to and received emails from Sean O'hara the Director of PostComm. It was PostComm that wrote the Act.
Please confirm what you are telling me, your interpretation is right but PostComm (the body that WROTE THE ACT) is wrong.
'Tis you that have it wrong, as I stated in the beginning. Why don't you phone PostComm to find out yourself?
