#16 par 4 Dogleg left that turns pretty hard. Overall there are more dogleg lefts here than rights but it doesn't seem to jump out at you. Perhaps a slicer of the ball would feel differently.
The green is sited along a ridge of dune with the usual complement of flanking bunkers.
#17 for us was a fill in hole which was a replacement for #18 which was out of play as they were rebuilding it and the range. We played a wonderful little uphill short iron to a tiny green that sloped pretty hard from left to right, and with the pin up on the left was a pretty tough shot. You couldn't see any of the green from the tee, and the bush was just left of the green, not to mention it was all carry over a bush-filled depression. A great little hole that unfortunately is not part of the normal rotation.
Interestingly in Australia most of the courses we played had a fill in hole which allows them to work on another hole without having to use a temporary green which is pretty smart. However, it may be that just gives them an excuse to mess with their courses too much. I haven't seen enough to make an informed decision as to which it is.
#17 par 3 (our #18 for our round) is yet another in a long line of solid par 3's that we saw throughout our travels. The hole plays right along the top of a ridgeline, with a huge falloff down to the right onto #16 fairway, and a pretty good falloff on the left also. The ground rises just enough on the way to the green with the vegetation to obscure your view enough to induce uncertainty. This uncertainty makes it hard to commit to your shot, which is always a good thing in my book from an architectural standpoint. There is actually room to miss short, which is the bailout, but since you don't see it the first time around you just do your best. Besides with a mid-iron in hand it is hard to convince yourself to lay up.
Fortunately there are some flanking bunkers near the front of the green that can save your miss from rolling far far away.
All in all a great course IMO and one I would certainly make it a point of playing again on a return trip even though that would mean leaving the Sandbelt. Easily a Doak 8 (One of the very best in the region and worth a special trip to see. Could have some drawbacks, but will make up for them with something really special.)
