Bloggsie,
Maybe the waypoint was named after the Alwyn Award, a very special award conferred, annually or more often in exceptional cases, by AOPA Australia, until some years ago ---- and, no, not when Dick Smith was President.
However, about the same time the Casawary column, the chronicle of the adventures of a boneheaded flightless bird, first appeared in the AOPA magazine. The column masthead was a masterpiece by a very talented young cartoonist.
Alternatively, maybe she is a he, located no entirely unadjacent to the YPPH area.
Tootle pip!!
