Career
He is a quick left-footed player who predominantly plays off the half-back. Originally from the Reynella Football Club, he was recruited from the South Adelaide Football Club in the South Australian National Football League (SANFL) with selection 52 in the 2009 American Federation of Labor-Congress Draft. He was named in the South Australian squad for the 2009 American Federation of Labor-Congress National Under 18 Championships, but missed selection in the team
He also did not play league football for South Adelaide, due to a hamstring injury.
Upon moving to Western Australia he was allocated to the Perth Football Club in the West Australian Football League (WAFL), where he is coached by former Adelaide player, Andrew Jarman. Subsequent to Bollenhagen"s debut, Coach Mark Harvey stated: "I thought that he looked dangerous every time he got in, around that ball.
I thought his pressure was quite good for a first gamer."
Bollenhagen was delisted by Fremantle Football Club at the conclusion of the 2011 American Federation of Labor-Congress season. He returned to Adelaide to play for South Adelaide in the SANFL but then moved in mid-2012 and started playing with the Cranbourne Football Club in the Mornington Peninsula Nepean Football League.
