Australia captain James Horwill highlighted a poor start after surrendering the series against the British & Irish Lions with a 41-16 defeat in Sydney.
The Wallabies went into the game with momentum following the narrowest of second Test wins in Melbourne but were outclassed in the final clash as the tourists ran in four tries.
After a nightmare start during which the hosts fell 19-3 behind they did claw their way to within three - only for the Lions to roar clear again and romp to their first Test series success in 16 years.
An emotional Horwill said afterwards: "We had too many errors early on and we gave them a head start. We started the second half like we wanted to start the first half. We let them get away with it and they were too good.
"You've got to give them credit - they played very well and were the better team tonight.
"We just had to hold onto the ball and build pressure and we didn't do that. We let them into the game and we let them execute the way they wanted to and they scored points.
"It was a bit disappointing from us in the scrum. We'd done so well in the first two Tests but we let ourselves down there a bit. We've got to work on that."
Later on, when addressing the crowd, the giant lock added: "I'd like to congratulate the Lions on their victory tonight and on the whole tour. The Lions tour is what rugby's about. The whole month they've been here has been an amazing atmosphere throughout Australia.
"I'd like to say thank you to the fans. Lions tours aren't the same without their fans and they've really brought a colour and excitement to rugby. Thank you.
"We dug deep and we tried as much as we could. To our guys - put your heads up high and let's keep working."
