Career
Blacklock"s acting career began on the stage and she spent two years in England acting in repertory theatre. Prior to the role in Number 96 she had played in theatrical productions of Don"s Party and Who"s Afraid of Virginia Woolf, and made a few guest appearances in Australian television drama series. The role in Number 96 began in January 1974.
In late 1976 there were plans to spin off the characters of Mummy and Daddy into a new situation comedy series titled Mummy and Maine and starring Blacklock and Dorsey, but the proposed series was not picked up by the network and the characters remained in Number 96.
Blacklock played in the series continuously until it ended in August 1977 and was in fact the final person shown in the closing scene of the last episode. During 1977, Blacklock appeared occasionally as a panellist on game show Graham Kennedy"s Blankety Blanks.
In the late 1970s she and her main Number 96 co-star Mike Dorsey created a stage show based on their Number 96 characters which toured clubs in New South Wales.
