No worries.
I've been here 6 yrs and since become a AU Citizen (I also keep my US Citizenship).
I came over on a work transfer at my request and my visa processing went very smoothly (both Temp and PR phases). I won't be retiring for several decades but am putting away funds into my Superannuation (similar to a 401k) so I'm prepared for it.
These days I would still get my visa, but it would take longer due to the various priority levels they assign based on skillset and job offer.
The process itself is straightforward, lots of paper and lots of waiting. It's the waiting that gets alot of people stressed, but eventually if everything is in order they do grant visas.
I'm new here and hope it's OK to ask some personal questions. How long have you been in AU? Are you retired there? How difficult was it to get a visa to allow you to become a resident?
Oh and thanks for the rent info.
