To anyone interested, and has any answers for a proper fix?

For some time I have been noticing  a squeaking noise coming from the rear of my Roadmaster when its under load. Originally it only appeared in second and third gear at about 2,000 rpm under load, but lately it seamed to get louder and in most gears under load.

I was not able to find anything in our local forums that seamed to cover the issue so I went into some USA forums and found several talking about the drive belt and pullies. It seams there was varied responses about how to rectify the issue and weather its a warranty issue.

Because I am stuck at home like many others by the Corona virus I decided to see if I could fix the problem myself.
I jacked the back wheel off the ground and proceeded to inspect the belts and alignment and found lots of dirt and dust build up. I decided to thoroughly wash and blowout all of the dirt and dust build firstly then proceeded to clean the belt as much as possible. (Using the wife's kitchen sponge scouror, which got me in trouble. 😉
This seemed to do the trick and for now the noise has gone.

I am very interested in whether any one in Australia has had the issue and what they did to fix the problem?

Your fix makes sense, I was thinking maybe the belt was adjusted too tight.  I've had similar on a couple of Harleys, belt adjustment &
cleaning fixed it.  I also made the stupid mistake of taking a belt cover off one of them for aesthetic reasons but soon put it back on.
Exposed belts tend to attract all sorts of nasties.  I've seen a few with rocks punched through the belt after being swept up from the road
& run into the pulley.  Rock might've broke but the pulley being metal & the rock being hard, the only thing to give was the softer belt
material.  Not nice seeing a gash or hole in your bikes driving apparatus!
Hope the cleaning fix does it for you.

If washing it well has quietened it down, that's a good result. Sometimes they squeal because they rub on one side. There are belt lubrication sprays and sticks that can calm down the noise.

In relation to stones getting into the belt, luckily they survive surprisingly well. I've seen a pic of a belt with a stone punched right through it and only found some time later. Here is a pic recommending that the belt only needs to be replaced if the stone is on the edge of the belt.
