Hi everyone, pls help me because I tried to google them but I can't find the answers. My husband is now working under visa 457 in Oz while I and our children are in Vietnam (we came back from Mel last October). My husband is going to apply for visa 186 direct stream so he will apply on-shore but his dependent are offshore. We want to do medical checks before logding but we are not sure how to do it. There are 2 issues: - I and my husband had medical examination and X-ray in Melbourne last September for another visa (less than 12 months) so Do we need to do another health check. If yes, which form and which checks shoud we do? - How can I do health checks for our children in Vietnam (8 & 1 year) (Last time we did health check after we submit visa application in Vietnam) Hope anyone can answer me soon! Thanks!
