Great finds !!
Frankston Victoria AUSTRALIA; had me confused for a moment. I was thinking US and I knew the first one in the States was at Valley Forge, Pa. I was a Scout at the Jamboree in Newport Beach, California in 1953 and today that area is the massive Newport Center Shopping Center (off 'Jamboree Road'). The only remnants of the '53 Jamboree is a plaque dedicated to the 50,000 Scouts who participated.
