This site is in military airspace - Restricted zone R155 - so absolutely no flying is permitted there till R155 is deactivated - usually after 5.00 pm on a weekday (except Fridays which is usually after around 3.00 pm) and usually all weekend and public holidays. (Need to check NOTAMS for area 60 Pearce PEX as sometimes special military airforce exercises are conducted after hours or on a weekend in which case R155 remains active.)
Very small ridge, works better than it looks like it should. Nice big grassy launch. If you get low you will be in rotor of the ridge in front, it's best to stay above take off if possible and top land. If you sink out land on the flat area immediately below takeoff. Can be flyable on the summer sea breeze, but generally only late in the day when the strength dies off.
