Chevron's right but you can get hold of a general purpose scanner receiver which includes the airband frequencies.Airband is on AM by the way not FM so you need to be sure the receiver has this mode.Most have the FM broadcast band too so they are handy for general listening.
Yupiteru is a very good make and Ebay is a good bet to find one.I live quite close to you and there is plenty to listen to round here.I quite like The Boot and Slipper too!
