I assume the short par 4 you refer to is #14. When I played there in 1980, if my memory serves me corectly, there was a bunker at the right front the green. If there wasn't, then the slope meant that a short shot was penalised. I recall that into the s-w wind, it was one hell of a shot. Balloon it and you were short, too low and you feared you were in the Bay behind the green (actualy, you were just in the native vegetation, virtually unplayable if you found your ball.
By contrast, #3 hole was bunkerless at that time.
And #12 had severe bunkers on the left side of the fairway short of the green - now it appears the fairway cuts off
completely.
PS I was going to post an aerial of your club Stockton (Newcastle) but the aerial definition is not up to it on Google-Earth, just as it is poor on the sandbelt and the mornington peninsula.
