In 2004, Des Hasler was appointed
head coach of the
Manly-Warringah Sea Eagles. In the
2005,
2006 and 2007 seasons he led the team to the
semi-finalsfor the first time since the late 1990s. Hasler gained the experience of
Geoff Toovey as assistant coach in the 2007 season. The team was a contender in the 2007
National Rugby League premiership, and finished second on the NRL ladder, losing the grand final 34–8
Melbourne Storm.
He coached Manly to a record breaking 40–0
2008 NRL Grand Final victory over the
Melbourne Storm
After failing to win the
1987 World Club Challenge with Manly as a player, he won it with them as coach in 2009.
He took Manly to the finals again in 2009 and 2010, but lost a final in each year to be eliminated from the finals.
He coached his 200th First Grade game on 13 August 2011 when Manly defeated their traditional rivals
Parramatta 26–20 at
Parramatta Stadium. The win was also Hasler's 117th win as a coach.
In 2011 Manly finished 2nd on the NRL ladder. Manly defeated the Cowboys 42–8 at the SFS for their first finals win since 2008. Manly went on to win the
2011 NRL Grand Final. He was named coach of the year at the
RLIF Awards.

A week after leading Manly to the 2011 premiership.
Hasler joined the Bulldogs on 14 November 2011 as head coach for the
2012 NRL season.
[7] He had immediate success as he took the club to finish eight places better than the previous season to the top of the ladder and collected the minor premiership. After impressive Qualifying Final and Preliminary Final wins; 16-10 over former club Manly-Warringah Sea Eagles and 32-8 over South Sydney Rabbitohs respectively, the Bulldogs were beaten in the Grand Final by the Melbourne Storm 14–4.
[8] At the
2012 Dally M Awards Hasler was named the NRL's coach of the year.
[9] In the 2013 NRL Season it was a disappointing season by his and the club's standards as they finished five places lower compared to the last season as they finished in 6th place and got knocked out straight away by the
Newcastle Knights in the Qualifying-Elimination final 22-6 at Stadium Australia. In the 2014 NRL Season Canterbury finished once place lower compared to the previous season and just limped home into the Finals Series in 7th place but nobody foresaw what was to happen in the finals that season, Hasler led his 7th placed Bulldogs through three weeks of sudden-death Rugby League to amazingly reach the Grand Final after impressively scalping past
Melbourne Storm 28-4 at AAMI Park in the Qualifying-Elimination final,
Manly-Warringah Sea Eagles 18-17 after Extra-Time at
Sydney Football Stadium in the Semi-final and
Penrith Panthers 18-12 in the Preliminary final at
Stadium Australia but they ultimately lost to hot title contenders
South Sydney Rabbitohs 30-6 in the Grand Final at Stadium Australia missing inspirational captain
Michael Ennis but the club, players and Hasler won a lot of creditors in their performances through the finals that year and for reaching 2 Grand Finals in the last three years.
Forget untried rookies I am sick of it, Hasler is first choice ........a distant 2nd choice is Cleary!
