There were so many Australian frame builders that built track frames it does make tracking down a particular builder almost impossible. Your frame doesn't appear to have any obvious distinguishing features.
I think you did the right thing by looking into the Holdsworth possibility. Often bikes were bought into Australia and sold after a season of racing. Does it look similar to other Holdsworths?
It does look like a strongly built frame with nice long pointed lugs that have been filed thin. I would guess at a 70's vintage. I also wonder if the rear brake bridge was drilled out by a previous owner. I would fill the holes in if I was to do it up.
I like it. I think it is worth doing up.
Best of luck,
Gary.
