The 31-year-old Pocock missed the first half of the season with injury but returned to action in a warmup game against Samoa, when he casually mentioned he'd be giving up worldwide rugby after the World Cup.
But there will be pressure on England to perform at the World Cup if they want to keep Jones as head coach.
The Irish have displaced the All Blacks as the number one team in the world while Scotland will be looking to better their progress, a narrow quarter-final defeat to the Wallabies, the last time out.
"We want to do two things; to do our best to win the tournament but also to show young people in Australia who are watching, how handsome the game of rugby can be and inspire them to play rugby back home in the future".
He'll have one last shot with the Wallabies, who tend to be contenders at World Cups no matter what their form leading in is like.
He is seeking Aus $10 million (US $6.8 million) for unfair dismissal - a major potential headache for Rugby Australia, which has warned of a financial loss in 2019.
The inclusion of Pocock at blindside at the expense of Lukhan Salakaia-Loto is the only variation from the team that started last month's impressive 47-26 victory over New Zealand in Perth.
"If you look at them historically, Tonga has punched above their weight at every World Cup and we are anticipating a ferocious battle on Sunday". Allan Alaalatoa got a starting spot in the front row, adding to his family's rugby legacy.

Chandrayaan-2 orbiter module functioning normally: ISRO
In these 14 days, ISRO achieved the status of Vikram Lander with the help of thermal optical photographs. So far, out of the 38 attempts of "soft landing" on the lunar surface, only 20 have been successful.
Reserve props James Slipper and Sekope Kepu have more than 200 test caps combined and are on a heavily experienced bench that includes veteran scrumhalf Will Genia.
Following a horror year in 2018, when the Wallabies won just four of 13 Tests, slumping to sixth in the world, doing well in Japan is seen as critical to winning back support for the 15-a-side code in Australia. For its part, Fiji has Semi Radradra, who played a rugby league game for Australia in 2016, on the wing and Australia-born Ben Volavola at flyhalf.
Fiji is renowned for their Sevens rugby, and Michael Cheika's men can expect a hard and fast game.
Japan is now ranked 10th in the world, and will be hoping to reach the quarter-finals for the first time.
Meanwhile, Fiji coach John McKee has named former rugby league global Semi Radradra on the wing against Australia after making all of his previous six test starts at centre.
"We go with high ambitions to get out of our pool and then believe that once you get into the playoffs we believe anything can happen in a one-off game", McKee said.
"Tonga will be a tough test for us, because they're a very proud nation, a very physical team, a lot of devastating players".
