Hi,
The 491 visa is a regional visa and therefore, your partner would be unable to work or live in Brisbane unfortunately
My partner is a Tiler and we’ve just put in our visa application, albeit, using an agent. I’d highly recommend using a MARA registered agent as the process is exhaustive, especially if you have to sort skills assessments etc
TRA did my partners assessment. I think there’s also another called VETASS? Or something along those lines
We were advised by the agent to do PTE as apparently that’s what tradies have more success with...I’m not sure how true that is, just the advice we received
Also, only post qualification experience gains points, this has to be proven by tax records, statements from employers or customers if self employed. Any experience prior to qualification doesn’t count
Hope this helps
