Photo page
From the Western Australia State Library collection.
This photo purports to be of Jim Grady, "First moter bike across Australia". I assumed that meant east to west.
I've searched the National Library old newspaper files, and Googled on, but found no further information.
If anyone knows any more about this chap and his "moterbike", I'd love to hear.
