New Sussex applied successfully to join the FMF after the protectorate was founded between Mercury and Nova England in mid-2018. The team first competed in the 2019 World Cup qualifiers, where they finished fourth in their six-team group with 13 points, missing-out on a play-off place on their head-to-head record with Talenore.
In the following year's EMU qualifiers, the team finished second in their four-team group with eleven points to advance to the play-offs, where they overcame Nova English Korea on penalties to qualify for a first ever finals.
