Domestic growth descent at Airport
Cairns Airport numbers for September continue a softer domestic growth trend:

Domestic growth for the month was 0.8% and International growth 1.8%. The airport noted that passenger growth aligned with seats so load factors were similar.

The numbers here are ex transfers and transits where it was also noted by the airport:
The 4% growth of transfer passengers includes strong growth in travel to Weipa related to expansion of Cape York mining activity. When measured by seat capacity, Weipa is Cairns seventh largest route with 16,200 available seats in September.
