In 2005 Melbourne film-maker Rob McCafferty completed a doco about the first 15 years of Meredith, called A Weekend In The Country.
It premiered at the Melbourne International Film Festival and won the coveted Audience Award.
It contains wonderful early footage and commentary from Jack and Mary Nolan as well as the festival organisers.
You can watch the full doco on YouTube:
