In my case it took much persistence.
You need to accept that in the first instances you will need to deal with your ISP as they are the first port of call. This will lead to much frustration.
In the end I was lucky that it got escalated and once the NBN tech's got involved there was progress but no fix.
One thing that did make a small difference is that the lead-in was recabled with a tight twist Cat6 type cable from DPU to NCD. We have a aerial lead-in which acts like a big old antenna, the Cat6 reduced some of that.
I was told by the NBN network engineer who came to visit that the VDSL modulates between 10 and 140 MHz. When RF enters the system in that range the NCD senses the change in conditions and turns up the power to overcome the 'interference'. For me this resulted in broad-band interference.
I wonder if this was caused by water ingress and the cable (either underground or in infrastructure) that is causing some kind of earth load and the NCD is trying to overcome it by turning up its output?
Your ISP should be able to detect line issues such as this with their tests.
