They competed for the National Rugby League's 2007 Telstra Premiership and finished the regular season in 2nd (out of 16) place.
The Sea Eagles went on to reach the 2007 NRL grand final which they lost to minor premiers, the Melbourne Storm (who were later stripped of this title after being found guilty of salary cap breaches).
In June English club Warrington Wolves signed 30-year-old Manly winger Chris Hicks on a two-year deal from the following season.
After defeating North Queensland at the Sydney Football Stadium 28–6, Manly played in their 15th grand final against Melbourne.
The Sea Eagles however did win the 2008 premiership, and, given that the Storm also lost its 2009 title, Manly have argued they should be the defending premiers in 2010, but again the NRL have refused to acknowledge this.
