GPS co-ordinates would be very handy

Eucryphia Lead is the obvious route to Ronald Cross, tho looking at it from Calders Lookout recently (on the other side of the Lyell Highway) it didn't look like much of a lead - just lots of deep, dark forest (which may be ok if it's the open variety). Any other info would be much appreciated (best spots to camp, water, scrub etc.).
Scoparia Lake looks like a likely camping spot on the maps, tho from memory, when I did Mt. Pitt, looking across it looked to be true to it's name (ie., scoparia riddled) & well below the ridge line. Are the Needle Rock Tarns any better for camping?
I know this is probably not a very oft visited area, but what better place to ask than this forum.
Cheers.
Stuart.
