Oh righto - so it is 50 months to be Q'd to be finalised, and then based on current trends - approximately another 50 months to be finalised - I was getting confused with the data being presented there, good to have a comparison against the volume currently on-hand versus the cap per year.
To be honest we are just glad Australia has such a program in place, unlike say NZ, with the new 870 visa at least there is an opportunity for long-term onshore stay instead of running through cycles of those visitor visas with the 6 months offshore in an 18 month period.
Thank you for sharing that other thread, have been lurking in there a bit - and looks like I will be for the next decade or so!
