aditya104,
That's the SACL booklet, nothing to do with the security regulations, and really quite misleading.
If you happen to have an ASIC card, it's good for the staff prices, instead of the extortionate retail prices the mug punters are forced to pay at most big airports.
At Sydney, $2.00 for a mug of coffee beats the hell out of $5.50 and more.
Tootle pip!!
