Hey I hope I posting this in the right place but I cannot find any answer online. So I applied for a subclass 820 visa for my wife and she's now on the bridging visa. I have a son who's already an Australian citizen. I was thinking about applying for a centrelink to help us since the visa took a toll on us, I was wondering if doing so might have any impact on the visa application? Thanks in advance!
