Production ended in 2004 with the completion of the fourth season. The decision had been made to discontinue production after the first three episodes of the fourth season aired in Australia to disastrously low ratings. The program was removed from its primetime slot. The unscreened episodes from that final season were broadcast with little publicity in late 2005. Season four was not shown in the U.K.

Deborah Mailman (Kelly Lewis) & Tasma Walton (Leah) also worked together on Mystery Road (2018) as Kerry Thompson & Mary Swan respectively.
