Hi Tabitha
Where did you find this?? I was so confused yesterday on the same issue!!! see my thread: http://www.pomsinoz.com/forum/migration-issues/213042-urgent-cpv-173-holders-please-come.html
Looks like i should just ignore the visa grant date and take the initial entry date as the start date.
Do you know whats the length of the medicare card they will first grant you when you initially enter the country?
Thanks
