Sorry Kelpie, can you point out exactly what legislation/ regulation requires all Australian Cabin Crew to have a first-aid certificate?
CASA requirements regarding cabin crew are vague at best. As far as I am aware, the only first-aid requirements relating to cabin crew is they need to know where the first-aid kit is, how to use it and how to operate an oxygen bottle.
Nothing in CAO20.11 regarding first aid certificates.
The requirements are individual carriers' preference.
I am happy to be proven wrong!
