Visa Help for AUSTRALIA

Hello - I'm looking for someone to help me in acquiring a tourist visa (the 6 month tourist visa) for Australia. I am a US citizen and have already applied (today) for my tourist visa. The tourist subclass 600 Visa application. I am waiting to hear back from the Australian visa office regarding my application. However, I'd like some assistance in making sure this gets completed correctly and also helping me to acquire a longer-term visa (at least 12 months after this). Thank you
