Those were the days

While pottering around in my chess library this evening, I cam across a pamphlet containing the 100 best games from the 1978 Australian Championship. While I will probably look at the games later, it was the field and format that I found more interesting.
In those days the event ran for 15 rounds, and this went for the Reserves as well. While the tournament attracted all the big names of Australian Chess, the top seeds (Robert Jamieson and Max Fuller) were only rated 2325. Terry Shaw, who finished in a tie for first with Jamieson and Fuller was only rated 2235! Future GM's Rogers and Johansen were rated 2180 and 1980 respectively.
The Reserves was won by Roger Farrell who scored a massive 13.5/15, finishing 1.5 points ahead of Joe Rush, who was playing under the flag of Papua New Guinea!
