The clash will be the first time the two sides have met this season, with Blackadder saying that added an extra layer of excitement of the occasion.
"There is an unknown element given that we haven't played the Waratahs so far this year, but that goes for both teams. We are just focused on being as prepared as we can be to put in the best performance we're capable of," Blackadder said.
"We know we have the game of our lives ahead of us but are not daunted by the challenge, we are looking forward to it. We've got a group of men who want this badly and who have the talent to do it."
The final will be played at ANZ Stadium in Sydney's Olympic Park and kick-off is at 9:40pm NZ time on Saturday night.
