Born in Fairfield, Sydney, New South Wales, Zadkovich had previously played for English Football League club Notts County, scoring on his debut against Chester City, as well as Queens Park Rangers and Australian side Wollongong Wolves. He has also made several appearances for the Young Socceroos, most notably at the FIFA World Youth Championship.
Following his time in England, Zadkovich returned to Australia in late 2005 and trialled for Sydney FC. He travelled with the squad to the FIFA Club World Championship and despite not making an appearance he impressed coach Littbarski, being called in as a short-term replacement for injured Ufuk Talay late in the season. After a 12 minute debut off the bench against Queensland Roar, Zadkovich impressed with his first start against Perth Glory (which included a goal), playing one game in Sydney's run to the inaugural A-League championship, earning him a two year full-time contract. He was allowed to leave the club in March 2008.
On 17 April 2008, it was revealed Zadkovich had signed a two-year deal with English club Derby County, although his registration was unable to be completed before 1 July. Zadkovich made his Derby debut as a second half substitute against Norwich City at Pride Park in October 2008, in a match which Derby won 3–1. He struggled with injuries during his time at Derby and, after only 7 appearances for the club, cancelled his contract by mutual consent on 23 January 2010.
Zadkovich made his debut at right-back in the last home game of 1st round 2010 World Cup Qualifications, against China, at ANZ Stadium on 22 June 2008. Australia lost this match 1–0, with Zadkovich giving away a penalty in the second half.
Zadkovich took part in the 2008 Olympics as part of Australia's national team (Olyroos). He scored from close range in a 1–1 draw with Serbia, Australia's only goal in an unsuccessful campaign. He also played against Argentina in what was Australia's best performance of the tournament.
