With the OZ passport, (a) must apply in person, (b) agents are not allowed, (c) if you collect your new passport in person, then they do not cancel your current one, (d) If you want the new one sent by EMS saving a long trip to BKK, then they cancel your current one. ???? on that stamp it says ''has been cancelled and REPLACED by PP number.............that you put in yourself. immigration would not be aware of this, until you go there with new passport.
