In WA there are some waypoints on the east-west routes, all oriented approximately the same longitude but sparated by latitude which when read from top to bottom say something about a rugby trophy:
WHO'LL
WINNA
?????
TROFY
or something like that.
Also, Tindal used to (maybe still has) have all the HOUNDs ringed around it.
In the 80s, it was GAFFA in the red centre. A nod to the great amounts of not "much out" there.
