I know of one applicant who has a master's degree who applied to an Australian major (whose educational requirements at the time were HSC - ie' A-level equivalent) for a CC job. Naturally, you can't get a master's without a first degree, and you can't get that without an HSC. Said applicant had enclosed their master's transcript with the application as evidence of education but was then told 'No, we need to see your HSC'... so it appears you need to do/provide exactly what it says on the form, as lateral thinking might not be one of their strong points...
The applicant got in, by the way, and has been generally loving it for a number of years now. So good luck!!
