Career
A pacy wingman from Western Australia, Wellingham became the fifth Indigenous football player on the Magpies list having been selected with the 10th pick in the 2006 American Federation of Labor-Congress Rookie Draft. Wellingham"s initial season at the club was spent with Collingwood"s VFL affiliate side, Williamstown. Due to VFL limits on the number of American Federation of Labor-Congress-listed players eligible for selection against non American Federation of Labor-Congress-affiliated clubs, Wellingham was demoted to the Williamstown reserves towards the end of 2007.
Despite this Wellingham was promoted to the Collingwood senior list to replace Chris Egan.
Despite being named an emergency in round 19 against Richmond, he did not make his Collingwood debut in 2007 and was subsequently been demoted back to "rookie" status. He survived the cut post-season, and remained on the Collingwood 2008 rookie list.
He then switched guernsey numbers, switching from the lowly 41 to Guy Richards" old number 21. In January 2008, Collingwood lost their sponsorship from the Transport Accident Commission after Wellingham was charged with drink-driving.
Wellingham was moving a car 100 metres up the road (so he says, the other American Federation of Labor-Congress players with him had been drinking) after being out on Saturday 5 January, when he was pulled over by the police.
The club fined him $5000. Before the 2008 Anzac Day Clash Between Essendon and Collingwood he was promoted to the senior list again and was initially named as an emergency, but made his debut when Anthony Rocca was unable to play due to injury. His pace, footskills, overhead marking and ferocity at the contest became valuable assets to the Magpies" side.
He played in the 2010 grand final-winning team
The Match Review Panel deemed the hit worthy of a five-match suspension, but due to Wellingham"s five-year good record, the suspension was reduced to four weeks, and reduced a further 25% to three weeks due to an early guilty plea. At the end of the 2012 season during the American Federation of Labor-Congress Trade Period, Wellingham was traded to the West Coast Eagles, Collingwood in return receiving the Eagles" first round pick, #17.
His first season at the Eagles was marred by an ankle injury sustained while using a trampoline during the pre-season, while his second season, 2014, was limited by injury and poor form. He has, by his own admission, been lazy, and many Eagles supporters believe that his first two seasons at the club have not been worth the draft pick given up for him.
In 2015, Sharrod proved that the Eagles had made the right decision to trade for him, playing a vital role in their astonishing climb up the ladder and Grand Final appearance under new coach Adam Simpson.
He averaged 18 disposals and 4 marks in 24 games as a reliable midfielder/defender.
