Internet Speedtest results - Frenchs Forest NSW - pathetic

Here is typical sample  of the Speedtest results at Frenchs Forest, NSW, AU for ADSL connection,
note, I seen much worse than this lately, and  this is after we had the NBN FTTN infrastructure installed, some 12 months or more ago,  I have not seen any difference in speed for past 4 years,  the highest  download speed I have seen is 8Mbps download some time ago, but after rolling out FTTN infrastructure and the FTTN box is sitting 500m cable distance (not direct distance) that I expected that even ADSL would  be faster, up towards the maximum theoretical speed of 12Mbps, considering 500m should be a whole lot better than the 3km of twisted pair copper back to the local exchange, but no, its still poor performing ADSL.
We had the big handover of Telstra infrastructure here in Oct/Nov (handing over of wires and poles from Telstra to NBN Co.) nothing more nothing less, although the emails and letters from Telstra gave the impression that we were getting NBN  (fast NBN) but that was hype, checking both Telstra and NBN websites, it still shows  that "fast" NBN service won't be  available here until approx April-June 2019.  As for the NBN FTTN boxes installed around here, I not even sure now are they functional or not, maybe just sitting there doing nothing. I really need some test equipment to plugin to my phone line to tell me how long the copper pair is,  is it connected  to the FTTN node at 500m, or still connected to the FF exchange at 3km ? I suspect we still connected direct to the  FF Exchange because  the ADSL is still giving piss-poor performance.  No wonder the Kiwis are laughing at us, they got 1Gbps broadband and we still messing around with 5Mbps or less. It just proves that Australia is a 3rd world country.
