Graeme Smith said he remained content with the efforts put in by his players after South Africa's heart-breaking loss in the World Cup semi-finals.
Smith was one of many South Africans to fail in St Lucia
Australia cruised to a seven-wicket win, but Smith said: "We are a team that shows good character but today we were beaten by a better team.
"We have been a little bit up and down but the guys have put in 100%.
"There are a lot of disappointed fans here, we know that. But hopefully we can repay them in four years time."
Smith defended the decision made by him and some of the other top-order batsmen to play big shots early on.
South Africa quickly stumbled to 27-5, and there was no way back.
But Smith said: "The top order's been pretty good throughout the tournament.
"It didn't work out today, but all credit to their bowlers. It was very hard for us to get any initiative back.
"They've got some quality batters and with 150 on the board it was always going to be tough to stay in the game."
South Africa have still not reached a final after five World Cup campaigns.
