Whisky Flat is near Brandy Creek.....Both are sign posted on the GAR between HH and DP https://www.visitdinnerplain.com.au...s/45/Hotham-to-Dinner-Plain-Trail_7424334.pdf
I had a good dig, but couldn't turn up anything definitive. There is a site, www.keywhite.com, that shows a *very* similar image (Whisky Flat Solar Research Site), but the last capture was in July 2019. I can't make out enough information from the partial advertising sign to assist in the location, and Google Maps doesn't have any streetview of that section of the GAP. I would suspect that it is somewhere relevant to the biathlon centre, but other than that I don't know.
Before posting here I did some Googling and all that returned, both with general search and maps search, was Whisky (no 'e') Flat accommodation - revealing (what I already knew) that Google is now 90% commercial search and the serendipitous knowledge results of yore are gone
Walking trail shows up in OSM but not Google Maps. https://www.openstreetmap.org/#map=17/-37.00407/147.18148
Nice one @cold wombat @Jellybeans I've grouped the Whisky* Flat cam with Dinner Plain but it turns out it's closer to Hotham than DP. I think I'll move both cams into the Hotham grouping and be done with any notion of DP as a separate area. (Perisher got really upset when I grouped the Wilson Valley cam with Perisher because it's below the snowline) *as suspected, maps shows it as a no 'e' Whisky
Going by the mention of solar research on the image, I'm pretty sure it is on the solar panels whose shadow you can see in Google maps: https://goo.gl/maps/M3pu96xmRycxT1f28 And which can see be seen more clearly in Mapshare: This is 100m or so north of the tunnel under the road.(which is just of the bottom edge of this image)
I XC ski that route every year in August from JB Hut to Wire plain Shelter hut and back . Whiskey Flat is near the Biathlon range and it is close to the GAR and car park. It has special appeal to me and I am pleased that this snow cam. exists.
