One leaflet is a roneoed 1970 guide to a 40-point nature trail near the junction of the Murray Valley Highway and the park entrance road. The references are to species of flora.
Also attached is a later guide (May 1974) to a different nature trail, one designed for motor cars, around the eastern side of Lake Hattah, well within the Park, near the camping ground.
Also attached is a previously unpublished typescript report by Geoff Edwards, dated February 1969, on a mammal trapping program he undertook while a casual Park Assistant working in the Park during vacation from Monash University.
The National Parks Service published a checklist of the birds in 1972.
