I thought I recently became eligible for Australian Citizenship, but after calling DIBP, I discovered my four years started counting after I was granted a bridging visa. What was the time I spent on a student visa before that not counted?
EDIT (to answer comment): student visa, bridging visa, temporary residence, permanent residence
EDIT: (to answer comment): no gaps; did not leave country while on bridging visa, only on other visas.
EDIT: I fulfill the residence requirement as quoted in the answer below. According to the residence requirement calculator, I was eligible two months after I think I should be, but it still doesn't match what a phone call to immigration said for the date. The person on the phone was not very helpful. All I could get was "that's the citizenship eligibility date in the computer".
