If this sounds like I'm gloating, I'm not but I would like to know if its just the normal timeline to 857 PR.
I've been here for 10 months on my (rather my wife's 457 business visa - she works for the University). After 6 months probation we could apply for sponsored PR but we did generally doing nothing for 3 months. A few weeks ago we decided to send off for out UK police checks, on their arrival we then went for our medicals in Adelaide and then sent off the visa application. A confirmation of receipt letter arrived a few days later and then 4 days after that an e mail came stating PR had been granted. I reckon it took less than 10 days from sending the application to PR being granted.
Too easy - as the locals rather annoying say!
