Yes according to Wikipedia but no citation. Came across it when I was looking for a way to get to Townsville.

https://en.wikipedia.org/wiki/Townsville_Airport

In 1993, when Cairns' new terminal opened, all the airlines, except Qantas, Ansett, Cathay Pacific and Garuda, stopped international flights to Townsville, and eventually by 1995 the remaining airlines ceased international flights to Townsville.
