Was looking at the stats of the last four Olympic games. Though Australia is undergoing a process of self-flagellation over their "poor" showing and the 2012 London Games, still the Australian still won more gold medals by population percentages than the United States, China or Russia.
Australia is a continent with a population of only 22-million people whereas the USA has a population of 300-million. (California's population is nearly double that of Australia.) We have an athlete base that is almost 14-times larger yet Australia beats us proportionally when compared to population numbers.. In other words for every potential gold medalist Australia has in any sport, the United States has 24-candidates yet Australia is producing a significant amount of winners for the little population that do have.
When it comes to sailing, surfing, or swimming Australia has produced the best. In fact modern surfboards today use technology from Australia.
At the London Games in 2012 Australia "bombed" but if the United "Bombed" we would have had scored over 100-gold medals versus our 46-gold. If Australia would have had an average Olympic gold medal count they would have scored about 20-gold medals versus their 7.
The Australians' blame it on their current cultural issues and looking back at the evidence I reluctantly have to agree. Australian swimmers were hazing hazing each other, acting act like college students rather than diplomats or athlete representation, and one sprinter was even parading around with too much bravado before the games opened stating how he could not wait to race Michael Phelps.
Now, they did do worse than they ever have in an Olympic games, BUT, per the amount of population they had to work with they placed 18th in gold medals per million population whereas the United States placed 28th out of 54.
This page lists Olympic medal results standardised by population. The thinking is that the bigger your population is, the better chance that your country might actually have a genetically predisposed person that can win a medal. Reasonably simple to do and although this statistic is by no means a perfectly accurate reflection of a country's relative Olympic performance, medals/population is, in my opinion, a better indicator of success than simple sum-medals, and is easy for the lay person to comprehend.

USA Swimming should do the numbers and maybe they might realize that their coaching arm,(ASCA), may be grossly behind in producing great coaches whereas China is searching the best down under in Australia.
