Kings head coach Deon Davids paid tribute to his players after their shock 26-24 Victory over the Waratahs in Sydney on Friday.
The men from Port Elizabeth fought back from a 17-0 deficit during the first half to beat the 2014 champions.
The result was a fitting reward for the Kings who impressed in losses against the Western Force and Reds in their previous matches on their Australian tour and Davids said his team's success against the Waratahs was due to hard work.
"It's been three long weeks but three enjoyable weeks," he said after the match.
"We worked hard for this one and I'm just glad for the improvement and for the result. We have this approach on focusing on the things that we can control, so we just kept working on our own game.
"There is a great camaraderie among the players. They enjoy each other's company and we enjoy being together as a group. We just focus on becoming better as a team and I think the boys deserve it.
"It wasn't any issue of me motivating them too much to do their best, i think they just want to grow as individuals and that makes a huge difference."
