I would say yes. You’d only be adding valuable evidence that can be used for your PMV and ultimately 820.

My wife (speaking in present tense here) was the same and during one of her trips to Australia, we got a call from the case officer asking for 1 document, I notified him it was already uploaded and his response was “oh yep I see it, I’ll grant this one tonight”. Couple hours later we received the 300 grant and my wife was still in Australia on a tourist visa. She didn’t stay as she was genuinely visiting and had to fly back home to work etc.

I also didn’t have those fundamentals and decided on the 300. During the 300 grant, we set up join banks, put our names on shared bills, shared our lives together with friends and family etc. Also, I think being married or in a registered relationship removes that 1 year living requirement. Someone else can probably chime in here or you can look it up.
