Hello, if I could kindly ask a few questions please.

I have travelled back to Australia in July 2021 for a few months or just a little longer. Before coming back I was/am on a lease, where my wife and son still are. I had previously completed a Tm30 for that. I was on a 1 yr extension of stay based on marriage as well as having the required Covid insurance.

My visa has since expired as well as the Covid insurance since arriving back in Aus.

I am pre planning and would like to ask.

.

(1) - Do I need to do another Tm30 when I return as I previously done so and lease still current?

.

(2) - I apply just for the 90 days NonO visa then afterwards apply for the extension of stay based on marriage?

.

(3) - Do I need to purchase a 1yr Covid insurance or can I just apply for a 90 day policy giving I will be then applying for the extension of stay, or will they then ask me to apply for a 12mth policy?

I think that is it, other than the COE, Aus travel approval on my end in which I can sort.

Any info would be much appreciated once again

Kind regards
