That inaugural "All Blues" side, the first football team assembled by the newly formed NSWRFL was: Backs: Charles Hedley · Johnno Stuntz · Ed Fry · Dally Messenger · Frank Cheadle · Albert Rosenfeld · Lou D'Alpuget Forwards: Harry Hamill · Arthur Hennessy · Bob Mable · Peter Moir · Sid Pearce · Billy Cann · Robert Graves · Herb Brackenreg Two further matches were played against New Zealand before their tour took them to the Northern Hemisphere, with Jim Devereaux also featuring for the Blues.

However, on the return leg of their tour, almost a year later, with the New South Wales Rugby Football League premiership established, the Blues won the first two matches they ever played under 13-a-side rules against New Zealand.

Later in 1908 the Queensland team, whose first taste of rugby league football was also against the visiting Kiwis, traveled to Sydney for the first series of games between the two states.

During the 1913 New Zealand rugby league tour of Australia New South Wales played four matches against the Kiwis, winning three of them.

The New South Wales team hosted 2 matches of the 1953 American All Stars tour of Australia and New Zealand at the Sydney Cricket Ground, winning 62–41 and 27–18.

Although the Blues continued their losing streak during Stuart's tenure, he is credited with restoring passion and pride to the NSW jersey and closing the gap between the two states.

In 2017, New South Wales were widely tipped to win the series as Queensland had a number of key players injured.

In game 3, New South Wales travelled to Brisbane for the decider, the blues would lose the match at Suncorp Stadium 20–14.
