A disappointed Waratahs captain Rocky Elsom says that the Waratahs will have to "live with the consequences" of their 24-27 loss to the Bulls.
The loss has put the Waratahs participation in the Super Rugby play off in doubt as they have played one more match than Australian conference leaders the Brumbies but trail them by 12 points.
"It was a terrible result for us, we wanted more out of that game than that and we are going to have to live with the consequences," said.
"They played very good field position at the end."
"We had the run of it for a lot of the game but at the end they played the style that they're very good at and came away with the points."
Bulls captain Pierre Spies skipper Pierre Spies said improved defence was the foundation of his team's victory.
"When you're playing away from home you need that defence, last week and the week before wasn't probably our best but tonight it was a lot better," the Springbok number eight said.
"It's always tough coming to Sydney and playing here, we had to fight it out all the way to the end, I am very proud of our team and it was an awesome effort all the way up to the last five minutes."
Waratahs Head Coach Michael Foley admitted his side, who dominated up front and had the lion's share of possession and territory, were understandably very disappointed.
"I thought for large parts of that game we did exactly what we wanted do to and had good control against a side that was obviously very fired up about their performance last week.
"There have been a number of games that have been particularly close and what it has come down to is that there's been a decision made or an error made that's cost us."
Foley though paid tribute to his team's effort, which was evident throughout the match.
"It's fantastic that the team has met so many challenges and put itself in a position to beat very good sides, like the Bulls.
"But for us to take that next step, we've just got to control those little moments that we can control."
The Waratahs will tomorrow travel to South Africa knowing that the season doesn't get any easier.
"All that matters for us now is to recover from the disappointment and to prepare well for next week.
"And when we get into next week's game, make sure we've dealt with the details in preparation that allows us to control the things that we can control."
