In March 2006 he and team mate Michael Beauchamp had a ten day trial with German Bundesliga club Nuremberg. On 1 July 2006 both players transferred to Nuremberg on season-long loans. Dean has struggled to get senior games only appearing on the bench for the first team, although he played 8 games in the Reserves scoring 5 goals.
Heffernan suffered a broken leg during the Mariners 4-5 loss to Sydney FC on 22 December 2007, due to a tackle by Ufuk Talay. As a result he was unable to play in the rest of the 2007/08 A-League season. Since returning from fracturing his tibia, he was selected twice for the Socceroos and was a stand out for his club the Mariners in their 2010 Asian Champions League campaign.
With the Central Coast Mariners in the 2009 - 2010 he had another stand out season, where he was named in the PFA team of the year and Four Four Two team of the year. Also scoring his first international goal for Australia against Kuwait. On 26 November 2009 Heffernan joined new A-league side, Melbourne Heart on a multi-year deal.
Prior to joining Melbourne Heart, Heffernan joined English side Huddersfield Town in Football League One to help prepare for a World Cup call up for the Socceroos. He completed the deal on 28 January 2010 after receiving his international clearance. On 30 January 2010 He made his debut for the Terriers in their 1-0 win against Yeovil Town at Huish Park. His first home game for Huddersfield was in their 1–1 draw with Carlisle United. Heffernan's last game for the Terriers was in their 4–3 win over Walsall. After Town lost in the play-offs, Heffernan returned to Australia to join his new team-mates at Melbourne Heart after making 15 appearances for the Terriers.
Heffernan left Huddersfield Town in the wake of their 2–0 defeat to Millwall in the play-off semi final. Heffernan had already signed for Melbourne Heart prior to joining Huddersfield so will play in the 2010/11 season for the Melbourne Heart. At Heart, he played most games in the first half of the season, but after getting sent off, his position was covered by Aziz Behich and he was not included in the starting lineup for many games afterwards.
On 25 February 2011, Heffernan moved to A-League side Perth Glory for the 2011/12 season. He will join Perth Glory for pre season training in August after he completes a short term loan deal with Chinese Super League club Liaoning Whowin.
