From the early 1970s, when tourism in the island was at its peak, Jersey attracted many of rugby's top clubs who could combine a break from their regular fixtures with a game against JRFC.

This period culminated with a very successful Centenary year in 1979, teams with international players came over to play and help celebrate this event, including JPR Williams.

This decade left the club with an unequalled collection of plaques and memorabilia, with teams coming from England, Scotland, Wales, Ireland, South Africa, Australia (the beachguard connection) and the Netherlands.

In the summer of 2010, the new Lord Jersey Stand was built between the 1st XV pitch and the Airport Road as was the Pavilion, with kitchen and bar, to the east of the main club facilities.

In June 2021, the British and Irish Lions squad visited Jersey for 10 days as they prepared for their ill-fated tour to South Africa.

Finally, Eddie Jones brought his England squad to the club during October 2021 as preparation for their successful Autumn International season where they beat Tonga, Australia and South Africa.

This trend continued in to 2022 when Leicester Tigers, London Irish and Bath Rugby all visited Jersey for training camps and all three played the Reds.

Prior to the start of the 2022/23 season, the members of Jersey RFC voted to unanimously approve breaking-out the professional arm of the club.
