Waratahs coach Michael Cheika has attributed his team's 25-20 Super Rugby victory over the Chiefs to their composure in the closing stages.
The Waratahs kept Super Rugby champions the Chiefs scoreless in the first half and led 15-0 after first half tries from Cam Crawford and Israel Folau.
In the second half the Chiefs fought their way into the match and eight minutes from time the Chiefs went into the lead for the first time with a try by Ben Tameifuna.
However four minutes later flyhalf Bernard Foley found space and sent a pass out to replacement hooker John Ulugia and he ran past Ben Tameifuna to score the match winning try.
Praising his side Head Coach Michael Cheika said, "I think that there's a belief in the way we want to play,"Cheika said.
"If you look at that last try, we started a fair way down the track with a short amount of time to go and we get back up there and create the opportunity to score.
"We were sticking to the style of game we want to play and that can only happen if we lay a platform around the contact area."
Looking ahead to the two-match tour of South Africa, Cheika was enthused with his side's newfound confidence.
"We're starting to build some belief in ourselves.... in each other and the commitment we need to make to each other, to work hard enough to win games."
