Agreed, the surrounding TAFs (YPAD, YMBD) might have been 'nothing great'... but I've found that Goolwa is usually worse than the surrounding airports. Particularly with a nasty west/south westerly, as is usually the case when it hits the fan in the area.
I've experienced some significant shear on final for the southern runway (19?.. it's been a while).. enough to go around and give it away. Usually as the westerly came over the buildings/hangars.
Can't remember re the cross strip, but am sure it was too short for a lot of aircraft.
