In 2011, the Illawarra Rugby League's centenary year, McGregor was named at centre in the Illawarra 'team of the century'.
McGregor joined the St. George Illawarra's coaching staff in 2002 as a strength and conditioning coach, a position he also held with the NSW Blues.

McGregor coached the Illawarra NSW Cup team in 2012 and 2013 before taking up the assistant position at St. George Illawarra. His successor at the Illawarra Cutters was another former Illawarra player, Ian Millward.
Following the announcement of the sacking of incumbent first grade coach, Steve Price, McGregor was elevated to coach of the top tier team in May 2014, initially until the end of the 2014 season. Following improved form, McGregor was announced as the full-time head coach for the next three seasons until the end of 2017.
In 2015, McGregor coached St. George Illawarra to finish in 8th position. This was the club's first finals appearance since 2011.
In 2017, many predicted St. George Illawarra go finish in the bottom four, due to a disappointing 2016 season, where the club were extremely poor in attack. In Round 1 2017, St. George Illawarra beat Penrith 42–10. St. George Illawarra would go on to lose in Round 2, but win the next 5 games in a row. Due to improved form, the McGregor was re-signed by the club on 8 June 2017, until the end of 2019. In the second half of the 2017 season, St. George Illawarra suffered a terrible drop in form with the club winning only 4 of the last 11 matches. This drop in form culminated with the club losing against Canterbury in the last round of the regular season. Before the match, St. George Illawarra only needed victory over their lower placed opponents to qualify for the finals as North Queensland had lost the earlier match. Due to St. George Illawarra losing the game, North Queensland went on to finish in 8th place and qualify for the finals. This eventually lead to North Queensland reaching the 2017 NRL Grand Final.
