The Brisbane Astronomical Society does its PFN every month... if the weather is kind to us.
Info is up on the BAS site
www.bas.asn.au, next one will be around 4 weeks away. We hold them on the Saturday nearest the First Quarter Moon, and we don't advertise because if several hundred people ascend the mountain (like last night) and there are only a couple of scopes... well you do the maths.
Next one is on the 10th May, weather permitting.
