Ah, ASIC cards........what a monster this is.
I hold an ASIC card, but work for an offshore operator that issues me with their own version of ID/security card. Their requirement is that I wear their ID card only, wherever I go.
I got cornered by a security gorilla at an Australian airport recently and was told in no uncertain terms (albeit in broken English by someone whom I suspect is a recent arrival) that under no circumstances was I permitted on the tarmac, and I would be in breach of Australian law if i did a pre-flight walkaround inspection.
My explanation that the company I fly for has a DOTRS-approved security program fell on deaf ears, as did my comment that I have been flying in and out of this particular airport for almost 30 years.
Like By George, I am a fugitive in my home country.
