Sorry I can't remember exactly how I filled things in now, but I know when asking for qualification to be assessed I listed my degree and didn't really mention CIMA, both for the skills assessment for CPA and the actual visa application. On the paperwork CPA send with a checklist, degree certificate and transcript are required, professional certificate is listed as if applicable. I did send the CIMA certificate, but I just didn't list it in the application (can't remember if I listed it as a secondary qualification, or if I just ignored it).
We travelled for 8 months before coming over to Australia so have only been here a couple of months. I managed to get the first job I applied for which was good and I start work next week, so life in Oz/reality is just about to start really.
