How about a planned caeser due to having had previous caesers before( this is one of the legitimate medical reasons)?Medicare won't cover an elective c-section for people from reciprocal countries. They will cover an emergency section or a planned section because of difficulties. Ie you find out two weeks before date that you can't deliver normally because of baby being breech or whatever. I'm assuming because you're talking about reciprocal you mean having a baby on 457?
Life is good, your situation is different (or your wife's) because you will be coming as a permanent resident on a 176 you will be entitled to the exact same Medicare as an Australian citizen.
There seems to be a lot of misinformation on other forums (not this one) about it making a difference being pregnant before you come to Oz. It doesn't make one bit of difference whether you become pregnant at home or in Oz your Medicare entitlements will stay the same.
