Bruce, a citizen of Hungary, migrated to Australia on a permanent visa several years ago. Last month, while riding his bike, Bruce decided to take another route and ended up finding himself riding on the highway. Unfortunately, Bruce was not as confident with cars driving past at 80km per hour as he thought he would be and was involved in a serious accident which left him in hospital. Thanks to his sister's help, he has now recovered. At that time, his sister, now aged 46, was visiting from Budapest on a Visitor (Subclass 600) visa. There is no condition 8503 attached to her visa and it is due to expire in two months. Bruce wants his sister to remain in Australia as he only has his brother in Australia, but he lives in another state. Bruce lives in New South Wales and his brother lives in Queensland. He doesn't see him very often. His sister has no relatives in Budapest and Bruce found that they really enjoyed each other's company during his recovery time and she reminded him of his mum, who he misses dearly after her passing last year from Covid -19. Which visa is the most appropriate option for his sister to apply for if Bruce sponsors her? What requirements would his sister need to satisfy in order for her to be successful in her application? (NB: You are not required to discuss the public interest and special return criteria). b) Does it matter where his sister is at time of grant? ) Can Bruce's sister travel on her Visitor (Subclass 600) visa to Budapest and then return to Australia after the expiry of her Visitor (Subclass 600) visa, to collect more things if she plans to stay in Australia long term? What would you advise? You are a registered migration agent and when preparing the visa application for his sister and sponsorship by Bruce, Bruce tells you that he forgot to include in his permanent visa application that he had a sister and seeks your advice as to whether this information would impact his sister's application. He suggests that if it would have an impact, that his brother could sponsor his sister and his sister wouldn't need to disclose Bruce as a relative in Australia. d) With particular reference to the Code of Conduct, discuss the professional ethical issues raised for you by Bruce's suggestion. What would you advise Bruce in relation to his suggestion
