Can't believe it's 12 years since I was scouring these pages for my own immigration! However my son and his wife have now secured Working Holiday visas and plan to come out early next year. What are the health insurance requirements? Most say it is but the imm site says it's not necessary for ppl coming from a few countries, including the UK. If it isn't needed, anybody know to what extent is the cover, same as resident for example?
