EMU787:........
god knows what spoonfed organisation you come from.....but then again you are one of the "believers"
yes I work for a really backward "spoonfed operation" called CX. ( if you'd bothered to read my posts you'd know that already )
Mate settle down, if your company ID card is accepted by all airports around the world it must be an approved one. I know for a fact that the one I wear in CX is approved by all the airports we fly into and I must display it whilst in the course of my duty. SIMPLE REALLY.
It's no different to other areas in Aviation. If Thai fly into Australia they are approved to do so by CASA, who have done the required checks on their operation ( engineering, flt crew, ID cards etc ) and that they comply with all the ICAO requirements.
The ID card is just one small part of the picture.
I would imagine that CASA do a thorough check of all airlines flying into Australia. And they conduct random RAMP CHECKS.
