I checked out the site the park has posted on the Stratford web site, and was only able to find it's location (in what I still call Bunbury) on the Stratford main site.
A couple ways to add some attention to it would be to add it to the PDGA course directory, and adding it to WikiMapia has proven to generate some good new leads from locals as well.
(go to the 'Add New Course' link)
I never did add Green Park or Cabot Park to the PDGA Directory, but I probably will when I check them out again, as I haven't played either course for some 10 years now.
Get in touch as well with the guys from SilverOrange, who held perhaps 3 charity tournaments at Strathgartney Park. I know it's essentially a pole hole course, but it's a start when you're trying to develop a base of players.
