2005–2010: Career with Richmond

Polo was drafted by the Richmond Football Club with the 20th selection in the 2004 AFL draft.

In his first season at Richmond in 2005, Polo initially struggled with the move from a small country town to the "big city", and was dropped to the Coburg reserves early on in the season. However, in the second half of the season his performances earned him a promotion to the Coburg seniors, where his performances continued to improve to the point where he was considered a possibility to debut for Richmond towards the end of the 2005 season.

After starring for Coburg in the early part of the 2006 season, Polo made his AFL debut in Round 6 against Essendon in the "Dreamtime at the 'G" game. He starred in the game, collecting 28 disposals and kicking three goals, helping Richmond beat their arch-rivals Essendon. Polo was rewarded with the Yiooken Award for his best-on-ground performance and was also nominated for the 2006 NAB Rising Star award.

In 2010 Polo was banned by the club for one week following a drunken incident in a Sydney hotel. This only added to the pain of Richmond's previously-winless start to the season. On 14 October 2010 he was delisted by the Tigers after 56 senior games in his six seasons at the club.

2011–2012: Career with St Kilda
