This is pretty bad, and I can't imagine why anyone would want to watch it (incredibly I saw it at the cinema in about 1978).
It's quite good for about the first five minutes, after which the plot is abandoned and we see a lot of the cast and crew in some sort of communal house discussing how things should develop. Apparently they eventually decide to spend the rest of the budget on LSD, and the final scene features the cast on crew lying around on a hillside tripping - "man this acid is really weird". Trust me, there are few things more boring than watching hippies tripping.
Max Gillies and John Duigan went on to have impressive careers, but I imagine they'd prefer to forget "Dalmas".
