I have a "Glory Red" (aka "Candy Apple") and needed paint. An auto paint shop here in Brisbane was able to supply it. Bad news is it is a three pack job!! They supplied it in three pressure pack cans. Believe me, it's difficult to get anywhere new the original quality. The ST1100 red is probably a one pack job, and may be able to be mixed up in small quantities.
So the short answer is, try an automotive paint supplier. Get the Honda Color number from under the seat and they'll be able to match it.
You might have to go into Tamworth or Narrabri, but you could ask the smash repair shop in Coona.
