Have just been looking at the original Alison routing of Barwon Heads, and was once again struck by just how accurately Berriman implemented it. I have tried to scan Alison's routing, but to no avail as the scanner will not pick up his very fine line drawings. Without the original, no use putting up the modern day layout. Alisons routing itself does not have many fairway bunkers to challenge the tee-shot, but on 4 of the holes where Alison did plan bunkers off the tee, they appear not to have been constructed, or were certainly not features in the 1980's, resulting in a course with little strategy off the tee.
Shane, the 'pot' buners at Victoria and Barwon Heads are not like the British pot bunkers dug out of the ground with sod walls, but are above the ground with no sod walls, but finely landscaped. You'll be able to find them at Camden Lakeside, the Ocean Course at the National and at the Dukes Course in St. Andrews Scotland, all designs by Thomson Wolveridge & Perrett. I think they are great on less interesting sites requiring a lot of earthmoving, such as The Links Hope Island and The Links Port Douglas, but personally I don't think are at all suited to the sandbelt or other sandy sites. They are a real 'trademark' of the TWP design. At Barwon Heads they are on the par 5 on the back 9 and on the following par 4. I understand that after those holes were modified the membership decided not to continue with any more of that style of bunkering. Have not seen them at Victoria, but heard they were not very popular there either.
