NSW Cup

The NSW Cup was known as the Reserve Grade/Presidents Cup/First Division from 1908 until 2002, and the NSWRL Premier League from 2003 to 2007, the NSW Cup from 2008 to 2015, the Intrust Super Premiership NSW from 2016 to 2018, the Canterbury Cup NSW from 2019 to 2020. The competition's lineage follows that of the NSWRL Reserve Grade from 1908 onwards.

The New South Wales Cup, run by the NSWRL, has been known by a variety of names and operated in several different ways since the inception of the NSWRL Premiership in 1908. Between 1908 and 1996, the competition was known as Reserve Grade and was competed for almost exclusively by reserve squads of each of the NSWRL Premiership Clubs, competing with that Club's name and colours. With the advent of the Super League war, and the resultant split competition in 1997, the NSWRL reconfigured the competition as the Presidents Cup. From 2002 until 2007, the competition was known as the NSWRL Premier League until it was reorganised into its present form as the New South Wales Cup in 2008.

With the competitions having merged back together, and with six NSWRL Premiership clubs having merged or became joint-ventures into three new NRL clubs (St. George Dragons and Illawarra Steelers; North Sydney and Manly; Balmain Tigers and Western Suburbs) the competition became known as the First Division and included these sides competing under their original name and colours.

The inclusion of these non-NRL clubs (along with the return of the Newtown Jets in 2000) in the competition signalled a move away from the 'reserve squad' competition it had become and became increasingly differentiated from the NRL competition with games played at non-NRL venues such as North Sydney Oval, Marrickville's Henson Park and Western Weekender Stadium at St Marys.

Another trend that began during this period was the phenomenon of NRL clubs outsourcing competing teams, with several NRL clubs choosing not to field sides in this competition and rather field either merged entities (as in the St Marys Penrith Cougars and Balmain Ryde Eastwood Tigers, both formed with NSWRL Jim Beam Cup sides) or form agreements with another club to take their place in the competition, those players being eligible for NRL selection, such as the agreement between Newtown Jets and Sydney Roosters for the 2006 season.

In 2007, Bartercard Cup club Auckland Lions joined the competition.

In 2008 and 2009, Jersey Flegg Cup club Central Coast Storm fielded a team in the competition. The team was based on the NSW Central Coast but acted as a feeder club to the Melbourne Storm. In addition, the Panthers were replaced by the Windsor Wolves and the Sharks were replaced by the Cronulla-Sutherland Cobras. The Canberra Raiders withdrew from the competition on 1 August 2007. The Newcastle Knights also announced a joint venture with the Central Charlestown. The team used the original Central Newcastle Rebels Name. The Parramatta Eels also formed a joint-venture with the Wentworthville Magpies to act as their Feeder Club in the competition from 2008 onwards. The Saints decided to no longer run a Reserve Grade Side, but would use the St George District Rugby League & the Illawarra District Rugby League competitions instead as their Feeder Team/s.

Two new teams have been added to the competition. These two new teams will have both previously played in the Jim Beam Cup. The Shellharbour City Dragons, previously known as the Shellharbour Marlins, will be the St George-Illawarra Dragons feeder side. The Bankstown Bulls, who were known as the Sydney Bulls, will act as the Canterbury Bulldogs feeder side. Bankstown will still field a team in the Jim Beam Cup. The Manly Sea Eagles have withdrawn from the competition and will have a feeder team in the Queensland Cup. Newcastle had also withdrawn from the competition, discontinuing the link with the Central Newcastle Rebels.

Season 2012 saw the return of feeder clubs for NRL teams St George Illawarra and Canberra. The Illawarra Steelers, in partnership with Illawarra Coal and the Illawarra Leagues Club re-entered a team into the league, the Illawarra Cutters. They previously acted as a feeder club to the Dragons. A Mounties Rugby League Club also entered the NSW Cup this season and is the Raiders' feeder club.

The 2013 season saw Wyong Roos enter a team in the NSW Cup for the first time. It will not be a feeder team to any NRL team. 2013 was also the first time in Rugby League history that teams with the names Western Suburbs and Balmain would not field a team in the cup, they played as the Wests Tigers. There is a current state of ambiguity surrounding this joint venture, and it is suggested that both Wests and Balmain will return as two separate clubs once financial requirements are met.

In 2014 the Auckland Vulcans were replaced by a side from the New Zealand Warriors. The Penrith Panthers will also be returning to the competition in 2014, replacing Windsor, who remain in the Ron Massey Cup.

On 29 January 2016, it was announced that Intrust Super had secured naming rights for the competition for a three-year agreement The name would have been decided not to be confused with the Queensland-based competition the Intrust Super Cup.

On 5 July 2016, it was announced that starting the following season, the Blacktown Workers would become the feeder club for the Manly-Warringah Sea Eagles in a joint-venture agreement. The Blacktown Workers Sea Eagles made their NSW Cup debut in Round 1 of the 2017 Season with a defeat to the Newtown Jets, before finishing 10th in the regular season and subsequently missing a post-season berth.

In September, Intrust Super extended its naming rights partnership with the New South Wales State Cup through to the end of the 2018 season.

On 27 October 2017, it was announced that Illawarra would be replaced by The St George Illawarra Dragons for The 2018 Intrust Super Premiership NSW season as part of a restructure in the competition.

In late November 2017 it was announced that as part of a re-brand, the Western Suburbs Magpies would enter the competition from the following season acting as a feeder club to the Wests Tigers, who had previously competed under their own brand.

On 2 March 2018, it was reported that the board of the Wyong Roos, feeder to Sydney Roosters since 2014, voted to cut all ties with the club at end of the 2018 season. As a result, the Wyong Roos did not take part in the 2019 Intrust Super Premiership. On 5 September 2018, it was announced that the North Sydney Bears would assume the status as the official feeder club to the Roosters NRL side until at least the end of the 2023 season, with Jason Taylor, a former North Sydney player and assistant coach to the Roosters, appointed head coach. Taylor, after leading the Bears to a third-place finish at the end of the regular season, was announced to have signed a two-year extension on 5 November 2019.

On 7 March 2019, it was announced that apparel company Canterbury of New Zealand won the rights to be the new naming partner of the NSW Cup competition which was renamed the Canterbury Cup NSW. The deal was announced to run to the end of the 2024 season. The NSWRL also announced that the new Western Sydney Stadium would host the grand final in each of those seasons under the deal.

South Sydney, having had a previous feeder relationship with North Sydney, would then field their own team in the Intrust Super Premiership, keeping the number of competing teams at 12.

On 10 October 2018, it was reported that the Parramatta Eels would field a team in the Intrust Super Premiership starting 2020, thus ending their relationship with the Wentworthville Magpies at this time.

On Friday, 27 March 2020, after round one of the season was completed, the 2020 Canterbury Cup NSW competition was suspended, and subsequently cancelled due to the COVID-19 pandemic, with no premiers being crowned.

On 8 June 2020, the New Zealand Warriors and Redcliffe Dolphins announced a partnership agreement, effectively withdrawing the Warriors from the Canterbury Cup competition. Through this initiative a number of players from outside the Warriors’ NRL squad will appear for the Dolphins in the Intrust Super Cup each week.

On 28 August 2020, the Canterbury-Bankstown Bulldogs announced a joint venture with the Mount Pritchard Mounties for two years. As part of the joint venture, the Mounties will represent Canterbury-Bankstown in the Canterbury Cup, ending their nine-year relationship with the Canberra Raiders. At the time the Canberra Raiders were set to go it alone in 2021 rather than form an affiliation with a NSW Cup side

On 10 November 2020, the NSWRL confirmed that the NSW Cup would return in 2021 with a 10-team competition, however Canterbury would no longer hold naming rights. A new naming rights partner is expected to be revealed prior to season launch on 3 March 2021.
