Marinoff was also named vice-captain to fellow league best and fairest contender Garner ahead of the final votes on Monday night.
The two midfielders join North captain Emma Kearney as the only AFLW players to be named in seven or more All-Australians teams.
It is the second time Garner has been made captain, after 2022.
Garner was joined by North teammates Alice O'Loughlin and now four-time All-Australian Ash Riddell, who is also tipped to poll favourably in the league best and fairest count.
Adelaide and Brisbane were well represented with four players each, with Crows veteran Chelsea Randall named on the interchange for her fifth nod while Lions captain Bre Koenen missed out after earning a spot in the extended squad.
There were no representatives from Melbourne, Richmond, Port Adelaide, St Kilda, the Western Bulldogs, GWS, Carlton, and Collingwood.
West Coast's 19-year-old gun Ella Roberts was the youngest player in the squad and one of 12 players to receive their maiden All-Australian blazer.
Fremantle ruck Mim Strom edged out Port teenage sensation Matilda Scholz for the ruck position for her first selection.
Scholz however, claimed the Rising Star award after earning 57 votes out of a possible 60.

Only eight players retained their All-Australian places after being named in last year's team: Chelsea Biddell, Emma O'Driscoll, Sophie Conway, Charlie Rowbottom, Ally Anderson, Riddell, Garner and Marinoff.
Marinoff, 27, reached new heights across 14 games over the home-and-away and finals series, boasting a league-high average of 30.5 disposals and 6.4 clearances.
For her dominance in the midfield, Marinoff was crowned the best player of the year by AFLW coaches - 12 points clear of runner-up Garner.
Garner's surprising history of not polling well in the women's equivalent of the Brownlow, not helped by teammate Riddell's equal mastery in the midfield, could come in handy for her Crows rival.
While she was judged in 2023 as the best league player for the second-successive year by the coaches, Garner finished equal seventh (14 votes) in the league best-and-fairest count.
Riddell, on the other hand, finished equal second with 16 votes.
