I wonder what ID will be acceptable? WIll it have to have a photo so therefore passport, DL, ASIC, proof of age or other govt issued card?
An ASIC is not a valid for of ID. It would have to be driver's license, ID card, Passport or some forms of Government ID (ie Military).
The real issue is going to be online or Kiosk check-in. If this gets up then it's going to be an absolute nightmare, as I can't see how they can check your ID without a physical person doing it. That will mean more staff and more cost to the airline.
I don't quite see the argument for checking ID, because if you are a serious criminal or terrorist you will probably have some form of fake ID anyway. The argument has always been that screening of bags and pax negates the reason to check everyone's ID. It all sounds like more of clampdown by the government to basically bring a Police State to Australia.
