Nice article, Noel and scary story.
Wave is where you find it. I've flown in wave in the easterly in the
lee of the Darling Range from Byford, the old Perth Gliding club site.
I was the only one flying and unfortunately there was an overcast at 3000 feet.
I've flown in wave a few times out of Waikerie and getting back to
Gawler from the east can be trickybecause of wave. You think you are
doing well in lift getting above glideslope when you fly into the bad
sink. Landed out a couple of times in the hill or Barossa Valley.
Also there is plenty of wave in Queensland. The Bunya Wave and
further north between Toowoomba and Bundaberg I've encountered wave
in the BD-4 resulting in a 10 knot increase in IAS for about half an hour..
Also at Boonah you can fly in wave.
One thing puzzles me, did Dave Donald not know of the existence of wave lift?

OBSERVATIONS.
It seems to me most Aus. soaring pilots have poor understanding of various
wave types and exhibit little or no desire to use them.
There are numerous wave sites in Australia.
W.A. has the Stirling Range.
S.A. has numerous wave sites that are rarely utilised. In fact I can count
on one hand those pilots who've exceeded diamond height in S.A.
However the sites begin just to the N/W of Pt. Lincoln, occur regularly in
the lee of the Mt. Lofty ranges along its entire length, and the South and
North Flinders Ranges.
A long time ago I took a series of observations while flying between
Adelaide and Leigh Creek en- route to Alice Springs at above FL310.
In the lee of the South Flinders I recall noting calculated lift was in
excess of 500 fpm.
Living at Arkaroola in the mid 60's Lenticulars were always visible to the
east whenever a pre-post frontal situation.
On the few times I had reason to drive to the east when these met.
conditions prevailed lines of rolling dust, parallel to the eastern range
escarpment and between it and Lake Frome were visible.
I reckon that wave will rival the one at Bishop U.S..
Victoria's Grampian Range probably provides the safest wave soaring site in
Aus. with almost unlimited outlanding ability in the area surrounding it.
I often wonder why various groups travel over 1000km. to attend a wave camp
when the availability to experience similar soaring often lies
close to their own back door.
