Every grade is operated by Wests Tigers RLFC.
The reserve grade team is just branded Western Suburbs Magpies, same as how SG Ball and Harold Matts teams are branded Balmain Tigers and Western Suburbs Magpies. Organisationally, there is no separation! Every player, every coach, every support staff member that works with these teams are contracted or employed by Wests Tigers. The $18m NRL grant, the $1.5m HBG funding, and West Tigers organic revenue streams contribute to operating NRL, NRLW, reserve grade, Jersey Flegg, SG Ball, Tarsha Gale, Harold Matts, Lisa Fiola, Andrew Johns, Laurie Daley, and development (cubs) teams, as well as the club's administration, sales, community programs, and media requirements.
Operationally, all teams are administered by Wests Tigers RLFC at Concord. So you can see how the club is spread very thin financially.
HBG contribute funding to running Balmain Tigers DRLFC junior teams - $275k in 2024. They also contribute $225k to Wests Magpies, for what I'm unsure. Perhaps to assist Lidcombe Oval match days. I suspect this figure will be much higher for FY2025 given Wests Magpies have taken out a 21-yr lease on Lidcombe Oval now.
Wests Campbelltown support junior footy in Western Suburbs junior district and macarthur, group 6. They have nothing to do with Wests Tigers RLFC.
This myth of Wests Tigers teams, rep Magpies teams, and rep Balmain teams being operated by different parties needs to end. It's all run by the one organisation - Wests Tigers RLFC.
