A new Regional Director was appointed to SA/NT region, who balked at the cost of manning Gove Tower. He cancelled it. The Tower was not yet fitted out, though I think some of the console was downstairs.
Flight Service staff took over the houses built for ATC - 3 has been mentioned but I thought it was more than that. They also hung a huge papier mache goldfish from the ceiling of the Tower - resulted in quite a few comments from pilots.
