From memory Cinema International Corp (CIC) became United International Pictures (UIP) around 1981. They retained the old company's initials for their video division as seen on the poster. At one stage the logo changed to CIC Taft, at least for the Aussie arm.
You can get info on Aus video release dates at the office of film & lit classification site.
The VHS collectors are passionate, but I have found that the popular cinema titles don't always carry over. They seem to go in for a lot of horror & obscure stuff. I think Ari is up on the whole scene.
