na, looks like an old clubbie board to me 
But i do know the guy 2nd from the Right,
That's old Harry High Pants
I work with Perry Hatchett and he told me how his dad and a few mates made a canvas board and used a double ended paddle. There is a photo at the pub in Scabs with Perry's dad Jim using it. I have the photo on my phone and will upload it later. From memory I think it was dated 1946?
My grandfather was a founding member at Cott Surf Club and we have photo's in the family showing the same set up. Also in a surf book I have (Australian Surf Art I think) there is a reproduction of a postcard advertising Cottesloe beach as a holiday destination which has a guy riding a board with a double bladed paddle (circa 1940's). Will try and dig out photo's from um's garage.
Aboriginals were seen standing up fishing on peices of dried bark by Jimmy Cook.Does that count?
