As part of the Monday afternoon trade, the Power will also receive picks 18, 24 and 56 while giving Lily Johnston to Melbourne, pick No.4 to the Bulldogs, No.21 to Brisbane and No.44 to Gold Coast.
Port Adelaide will still hold the first South Australian pick in Monday's draft, ahead of the Adelaide Crows.
A premiership player and one-time club leading goalkicker, Lamb will be a welcomed asset in Port's midfield following inaugural captain and competition powerhouse Erin Phillips' retirement from the sport last October.
The 29-year-old has played 67 games and kicked 25 goals at the Western Bulldogs since making her debut in the opening round of the first season.
"We are really excited to welcome Kirsty to Port Adelaide," club list manager Naomi Maidment said.
"She dominates in the contest, has good offensive ability and the capacity to hit the scoreboard.
"She is someone we have kept an eye on over the last couple of years."
Bulldogs teammate and All-Australian Katie Lynch also departed the kennel in favour of a move to Gold Coast, while Suns club champion Lauren Ahrens moved in the opposite direction.
Melbourne premiership player Maddi Gay has sealed a trade to Essendon, with Collingwood All-Australian Ash Brazill returning to Western Australia's Fremantle.
Named vice-captain of the Magpies in 2019, Brazill leaves the club after 32 games across six seasons.The 33-year-old, who was also a foundation player in Collingwood's Super Netball team, retired from the code last August following a Commonwealth Gold Medal (2022) and a World Cup Championship (2023)."I'd like to thank the club for my time in the black and white," Brazill said."I came to Collingwood with a dream to play both Netball and AFLW and the club allowed me to do so.
"It's now time for us to head home to Western Australia and spend time with our family."
The final day of the AFLW trade has been the busiest in the period, with inaugural Sydney player Aliesha Newman moving to crosstown rivals GWS earlier in the day, while the Gold Coast have said goodbye to Essendon-bound Bess Keaney.
