Central Coast Mariners
In 2010, Sainsbury was signed by the Central Coast Mariners where both he and fellow Central Coast Mariners team mate Marc Warren were selected to spend two weeks at Sheffield United’s Academy as part of the two clubs' partnership.
His senior debut came for the Mariners on 24 November 2010 in the F3 Derby against the Newcastle Jets, making a total of 9 appearances in the first team that year. During the successful 2011–12 campaign which saw the Mariners win the A-League Premiership, it was announced he had signed a two year contract extension with the club on 24 January 2012.
After breaking into the first team in the 2012-13 A-League season, Sainsbury formed a formidable partnership alongside Dutch defender Patrick Zwaanswijk which helped the Mariners secure their maiden A-League Championship against the Western Sydney Wanderers in the 2012–13 Grand Final. The Mariners won the game 2–0, which was played infront of 42,102 spectators at Sydney's Allianz Stadium. Following the game, it was speculated that Sainsbury had attracted serious interest from European clubs Southampton FC, Roda JC, FC Basel and Middlesbrough FC. Former Socceroo Mark Bosnich rated Sainsbury as his man of the match. The official award went to Daniel McBreen.
In March 2013, Sainsbury was nominated for the NAB Young Footballer of the Year which was eventually won by Marco Rojas. Sainsbury was named the Mariners Player of the Year for the 2012–13 season. He was also named in the official 2012–13 A-League Team of the Season as well as several other unofficial teams of the season.
Sainsbury was frequently named in Football Australia's A-League Team of the Week during the 2012–13 season. He was selected 9 times during the season, with only Nikolai Topor-Stanley receiving more selections.
Sainsbury signed for PEC Zwolle in the Dutch Eredivisie on a two and half year deal in January 2014. Sainsbury immediately was placed in the starting line-up, making his Eredivisie debut on 6 February 2014 in an away game against FC Utrecht. PEC won the game 2–1, but Sainsbury had to be replaced after 72 minutes, after falling on a depressed sprinkler, hurting his knee in the process. It was discovered after the match that Sainsbury had fractured his kneecap on the sprinkler, an injury that would end up ruling him out for the remainder of the season. Fellow Australians Tommy Oar and Adam Sarota played in the match for Utrecht.
His club PEC did end the season on a high note when they won their first major trophy in the club's history by defeating league champions Ajax 5–1 in the 2014 KNVB Cup Final, also securing European football for the first time as well.
Fully recovered from his knee injury, Sainsbury was reinstated in PEC's starting lineup for their first game of the season; the 2014 Dutch Supercup. The game was played against the same team that PEC defeated for the KNVB Cup-win, the league champions of 2013–14; Ajax. Sainsbury was part of a defense that kept a clean sheet in a 1–0 win, securing PEC's second major trophy in the club's history in the space of 4 months.
Sainsbury retained his place in the starting line-up for the first league game, at home against FC Utrecht. Lightning would strike again, as Sainsbury was subbed off with an ankle injury after 30 minutes of play, making it the second time in a row Sainsbury was forced out of a league game with an injury, both times against Utrecht. PEC won the game 2–0.
Sainsbury was selected in Australia's squad for the 2011 FIFA U-20 World Cup where Australia finished bottom of their group with one draw and two losses.
In September 2014, Sainsbury made his International debut for Australia in a friendly 2–0 loss against Belgium.
