One thing to correct, I assume you mean old Telstra infrastructure. The Optus infrastructure they were planning to use was the now 20 odd year old HFC cable network which they have decided is too far gone to be useable. Plenty of people in the industry could have told them that.

One of the great issues now (Ironically easier to find an answer to on the worst NBN technology, that being FTTN) is if a performance problem is related to the NBN side of the network or your RSP. I suspect a lot is down to the RSP level and if they have bought enough backhaul to the point of interconnect. If they have not then it will immediately show up as performance degredation at peak times. If they run the same sort of contention ratios that they used to it shows up fairly spectacularly when people have up to about 80ms/sec connections sucking the backhaul dry.

The bit that is harder to prove is if the FTTN component is up to the task in the backhaul from node to POI. If it is the same as the older NBN connections it is completely transparent to the user. If I do a traceroute to google for instance, the first hop is apparently the bendigo POI. 100+ KM and at least 5 hops away.
