That RD cable stop seems like a clue. I don't recognize it though.
What's the BB threading?
no name for the moment, but with those shorty dropouts (and these are the style that sometimes are engraved "GPM" but often "Columbus" or yes, even "Colnago") I think it's a late '70s, more likely an early '80s, that just kept some of the older frame details (and it may have had TT cables guides that got "drewed, ground off, when this was repainted and given the false decals).
I'm afraid that chainstay cable stop-with-ring doesn't tell me anything by way of a builder...since you're in Perth it could be Aussie, European or Japanese (or all of the above!) but seems like many of these oddballs in OZ turn out to be domestically made.
What's with those forkblades: are they round? Photo kind of makes that impression...
this is a fun puzzle minority. head and shell look so nice yet seat stay vent holes were not closed. work where stays meet dropouts and presence of vent holes mark it as a production bike.
bottom bracket fittings look economy japanese.
seat binder looks to be a gripfast.
let's hope we hear from T-Mar on this...
Well a bit more info, BB seams to be english threaded (left hand threaded fixed cup), seatpost that was in there was 26.8 and seemed a nice fit. The only thing stamped on the BB was "110" so maybe not mass production (it was also stamped on the steerer tube, so unless both parts were stamped later in life it would seem the forks go with the frame). Rear dropouts are Columbus and fork blades aren't round.
well, probably not Japanese even with the BSC/ISO threading in the BB. Given the Columbus-branded dropouts (and some of that European gear on it that may be original) I'd go with "Australian", though it could be an import from the UK or Europe. Very slim chance of a Panasonic-built frame using Tenax tubing, but the chances are low.
28.6 post says it might be Aelle if it's Columbus tubing, might be plain-gauge 531 if Reynolds.
Any sign of "rifling" inside the steerer butt end? I'd be surprised if so, but that would point to "Columbus" tubing.
How do you know for certain that it isn't a Colnago?
You know a product isn't authentic when the guitar says Martian or Gisbon, when the tape cassette says Maxwell, when the car says Chevie, when the bike says Puegeot or Colango, when the tire says Vitorria, when the bottle says Jim Bean, when the can says Bugweiser.
Okay, so it has an English BB?

Real cyclists use toe clips.
the mystery deepens...
What do mean strip and restore? the paint looks nice to me but could use a good waxing (and if your the type a little light polishing compound)
I bet a waxing and overhaul will do wonders for that old gal

Well, that's unexpected^
It's "*****d" all right, but not the smaller 5 curved ridges you'd see in a Columbus steerer. You have 6 fatter and straight ridges. so it's a Japanese steerer (I can't remember if this is typical Tange or Ishiwata, but one of those) and therefore must be a JP fork and since the serial numbers match...probably JP tubing for the frame. Doesn't automatically mean that it was built in Japan, could still be made in OZ from a JP tubeset.
Following up: getting weirder...Ishiwata steerers used wider straight ridges (like these) but the one catalog I have access to shows 5 of them, not 6. Tange steerers had 6 ridges and they were fatter than Columbus but they spiraled, like Columbus.
I can't find any examples (yet) of 6 straight ridges in the steerer, but I have a nagging thought that it must be Japanese. I think John D Thompson must know...
Was anything ELSE stamped on the steerer besides the serial number? Most Tange forks were stamped as such...
I think from memory that some Miyatas built with Tange tube sets were 26.8 seatpost as well, so that would tie in with it being a Tange tubeset.
The 26.8 seatpost size was very common for a lot of Japanese seat tubes that used a 28.6 OD with a 0.9 wall thickness, both Tange and Ishiwata had tubesets of that spec, but with Tange it was more common...shows up even more in steel Mtn. bikes.
Another factoid is that Tange was a huge supplier of finished forks to hundreds of brands that decided it was better to buy them from Tange rather than build a fork themselves, not to mention all those they sold to average folks as after-market replacements.
Al this to say: I agree that your frame is very likely made from Tange tubing, very long-winded.

Plan is to paint it red with maybe gold on the head tube & seat tube, a set of Mavic MA2 rims and a Shimano 600 arabesque groupset.
