Byrne-Jones, who finished second in the count last year, polled 159 votes to go one better in season 2020 and score the honour ahead of red-hot favourite and Brownlow Medal runner-up Travis Boak.

The 25-year-old polled best and fairest votes in 18 of Port Adelaide's 19 matches throughout the season, displaying his remarkable consistency as the club won its fourth minor premiership before bowing out in the preliminary finals.

Boak (136 votes) finished in second place, but also claimed the Fos Williams Medal for the best team man, while captain Tom Jonas (129 votes) was third after another solid season in the backline.

Young midfielder Zak Butters finished just outside the top-three with 121 votes, but was recognised for his breakout season with the Gavin Wanganeen Award as the club's best player under the age of 21.
