Gerry, G'day.
The photos are, Scented Sassafras, a giant Black Olive Berry and the 3rd image is Pinkwood, all on Errinundra Plateau relatively close to the Coast Range Road, east of Errinundra Saddle. The creek is Little Oakey Creek just before it flows over the Errinundra Escarpment and the last shot of the Cabbage Trees near Yeenung River, just off the Pacific Highway, East of Cabbage Tree Creek township.
jcr, The area from Thurra to Wigan including the Cicada Track is closed because of recent fires. No one from Parks Victoria knows at what stage the clean-up is at after the fire. I know that much.
What you have suggested for Croajingalong is one of the areas that I can't get solid info for, except that the area is temporarily closed. I haven't done the entire walk that you have mentioned. I've walked from the bridge over the Thurra River to Wigan Inlet and from Mallacoota south into the first of the giant sand hills.
The Gippsland Lakes I know well from the water. I race in the Marlay Point Race each year, which is the reason for my trip to Victoria. I've spent much time on the Gippsland Lakes, on and around Raymond Island and on the dunes of the 90 Mile Beach near Locks Port and Lakes Entrance.
The only other areas I've explored in East Gippsland are Little River Gorge (slightly), Errinundra Plateau (Errinundra I've been to often), Bemm River and the Snowy down past Marlo and along fire trails (mostly) in Indi and Byadbo. Any other recommendations would be really appreciated.
I've been through Omeo but I didn't stop because of bad weather. Where at Omeo would you suggest is interesting, to walk to?
Images from my most recent trip to the Gippsland Lakes, during April last year.
