Trying to locate an airport

Hi all, I just downloaded the premium flightradar24 on my iphone and I have all airports with the exception of Rockhampton (ROK) airport in QLD (which is closest to me) It even has more regional airports, but not Rockhampton. It is in the airports database but just does not show up. Any ideas?
Cheers,
Nick

EDIT - After reading further I assume this would be as no one has a receiver or similar required in this area? As I have noticed that planes that are due to land there also disappear..
