After 3 long years and lots of whinging Chorus have found the broken section and fixed my internet - from 1-3 mb down 350kb up to now on 12mb down 1mb up

As is the case with most geeks I'm always looking to the next best thing, UFB is a few years away for us so I was hoping I might be able to get VDSL. I'm not cabinetised, we are connected directly to the Johnsonville exchange which I'm told should have VDSL capability (this is from a mate so not sure on how reliable the info is).
The pre-qual site for Telecom says not available, is there a way to get a manual / actual pre-qual done to determine if my line will support VDSL?
TIA
