^a Congressman Underwood recorded 26 sporting events, but the results for wrestling listed the freestyle and Greco-Roman medals separately and the results for weightlifting listed the clean and jerk, snatch, and overall medals separately. The football tournament was not held because newly imposed OFC/FIFA regulations on player registrations conflicted with the South Pacific Games system and the tournament was not sanctioned. The official site listed 22 sports.
^b The Guam Bodybuilding website reported Ricky Collins as winning gold in the heavyweight division for bodybuilding at 1999 South Pacific Games, but this may not have been an official event in the 1999 Games. The sport is not included in the list above as it was not mentioned on SPG 1999 website.
^e Swimming: Three were 34 medal events contested, 17 each for men and women. The 5 kilometre open water events were introduced at the 1999 SPG. Swimmers from American Samoa, Fiji, Guam, New Caledonia, Northern Marianas, Micronesia, Palau, Papua New Guinea, Samoa, and Tahiti competed.
