I am currently on my first O-A visa, and it expires in January 2024. I know I can renew / extend it for another year, but I cannot see the cost and whether I can continue to renew indefinitely? I return to Perth Australia next week for a daughters wedding, and will be there for around 5 weeks. I am wondering whether it might be better to apply for an O-X visa from the Sydney embassy while I am in Perth? This would in theory give me at least 10 years (5+5). I like the fact that my money can stay in Aus, like with the O-A, where it can earn interest. Can the O-X be further extended, or do you have to start with a new visa application? Any advice would be greatly appreciated.
