Scott,
Your observation of Paraparaumu is interesting.The crumpled gound there almost dictates there is no need for fairway bunkering.There are so many great driving holes there simply because of the land - 1,2,4,8,11,13,15 and 17.
Its hard to see where you would put them.
The West Course (MacKenzie) at Royal Melbourne is highlighted by the influence of fairway bunkers - 2,4,6,8,10,,11,12,17 and 18 - but Russell's East has almost no fairway drive bunkers after the common bunkers on the 1st shared with the 8th West.
2,4,5,9,10,11,12,14,15,17 and 18 have no drive bunkers but the recently redone 7th and 8th holes now have them.
In contrast he did quite a few at Yarra Yarra.
