He was a successful striker in his youth years, but had difficulty finding his goalscoring form as a senior. As he only managed to score 11 goals in his first three-and-a-half years as a senior, Augustinussen was stamped by a media pundit as being "not the fastest moped on the dockside" ("ikke den hurtigste knallert på havnen") in August 2003, and did not look like cutting it at the highest sporting level of Danish football.
However, Augustinussen was moved back to the centre midfield by new AaB coach Erik Hamren, where he established himself as a consistent part of the starting line-up. He was named team captain from the beginning of the 2008-2009 season, and led AaB in the 2008-2009 Union of European Football Associations Champions League tournament.
In total, he played 283 games and scored 36 goals for AaB, including 223 games and 29 goals in the Superliga until May 2009.
In April 2009, he signed a three-year contract with Austrian club Football Club, effective from July 2009. After one-and-a-half year in Salzburg, Augustinussen was released from Salzburg of his own will. On 30 January 2011 AaB announced that they had signed Augustinussen on a three-year contract.
