Have you got the pots/lots for Moonee Valley? It'd be interesting as it'd be the shortest straight for a Metropolitan track in Australia. The 1000m has a 13.8 win % but I can't find the pots/lots. (10.5% for 1200m).
For WA the provincial tracks have good long straights so wouldn't pass your test. There are a couple of country tracks with shorts straights e.g Toodyay, but don't race often enough.
