Soo good to see those photos, mine are with a family member and I have not had a chance to attempt to get my hands on them and make a copy, back in early 87 we went through Monash with a friend from Adeliade and had a ball on the way back to Sydney after tripping for 6 weeks across the East & South Coast then up to the Alice through Adelaide and a bus trip to Uluru.
I believe it's not like it was due to insurance costs.
