England have now won four of their past five games in Oceania, having won just one of the previous 12 away matches against teams from that continent.
Saturday's victory sets up a thrilling decider in Sydney next weekend, and Jones has no doubt it is the home side that will be under more pressure.
"It's 1-1. And the pressure's on the other mob now," he said. "So they've got to deal with that pressure. We'll find ways of getting better.
"It was a good effort by the boys. We just tightened our game up a little bit this week.
"The boys carried out the game-plan really well, and played with a lot of intensity, a lot of passion, and we had three new caps. Incredible.
"It's just time together. We're a very young, inexperienced team. It takes time to put things together, and we'll be more cohesive next week."
There was one big negative to come out of the game for Jones, however, as Maro Itoje failed to return to the field after undergoing a head injury assessment.
Itoje collided with Hunter Paisami shortly before the interval and Jones later confirmed the lock will play no part in the deciding Test.
"The medical situation with Maro is that he will be out next weekend," Jones said.
Prior to this weekend's fixtures, Itoje's 83 line-outs won in Tests since the beginning of 2021 was at least 21 more than any other player from a Tier One nation.
