Career
Gardiner was recruited from the Sandringham Zebras and was pick northern 23 by Geelong in the 2001 National Draft. Gardiner was also runners up in Sandringham"s best & fairest and Under-18 Victoria Metro representative in 2001.
In 2002 Gardiner debuted for Geelong"s senior side later the same year.
Gardiner was traded to Street Kilda Football Club during the 2007 trade week, along with fellow Cat"s player Steven King for Street Kilda"s draft selection 90. He had an indifferent year, playing 12 games, including the qualifying final against old club Geelong, and kicking 9 goals but in the end it was not enough to retain his spot on the Saints" list and he was delisted at the end of the season.
He has since returned to amateur football in the VAFA.
