I know how you feel.... I submitted my application towards the end of November and I've been checking emails like crazy every day. I'm on a tourist visa that expires in June, so I'm not too worried. But 2 days before I arrived in Oz (March 13th), my CO reiterated that my visa is due to be granted at the end of April. Surely, if there was a delay, she would have said something, it was only a month ago.... I arrived in Oz with a ticket to NZ booked for April 30th, and I'm really hoping I don't need to change the date....
I'm so glad there's a forum like this to be able to read others' experiences...
Good luck... Hopefully, yours will be through soon!
