Wanting to set up an auto-deposit into a vanguard Australia ETF but have no idea what i'm doing. Any simple recommendations?

I'd like something reliable but slightly high growth. But I'm just not across the language or anything. I know there are Youtube videos, but it's honestly all too confusing and I'd rather just have someone recommend something to me. What's worked for you?

I'd like to deposit about $200 a week. If there's an option where i don't have to pay taxes at the end of it but I don't know what the equivalent of it is for Australia.

THANKS
