Original 1963 release
THE GIRL IN LOVERS LANE was originally released in Australia in 1963 by Regent Films. The classification is unknown to me.
According to trade magazine The Film Weekly Motion Picture Directory 1964-65, the Sydney film listings for July 1963 to December 1964 credit it as being released on 12 July 1963 with a running time of 75-minutes.
The 1971 rerelease that you list was originally submitted in a print running 77:55, before being censored down to 76:27. It would appear this version is a little longer than the 1963 release. This minor B film seems an odd title to reissue. The IMDb lists the original American running time as 78-minutes, which suggests the first 1971 submission was complete.
I have no proof, but the reissue may have been through Roadshow. It was originally released by The Film Group in America, whose product ended up with AIP. In 1960s Australia, AIP product started to be sparingly released by Roadshow, and around 1969 they appeared to be the sole distributor.
