Hi All, Can anyone confirm what the health requirements are for a parent to pass the medical for Visa Subclass 870? The mother in law is considering applying for this VISA, however she has recently had a heart attack due to unstable angina, she needed a stent inserted. She also has some other health ailments such as high blood pressure, knee replacement, high BMI. I understand that private health cover would be required for her when in OZ, does this therefore make the health requirements for this Visa less stringent than the requirements for a PR visa? Is there a gov website where I could find this information? Any advice appreciated. Kind regards Andy
