Yeah, greg, I've seen the movie... in the 70's so I'm scratching my head trying to work out what it was about. I remember it was all mysterious and spookey and the last wave had unearthed some aboriginal artifacts which revealed something or other. I remember the huge flood, the sea, underground, the dialogue was very fragmented so I can't remember much.
