No one ever tries to replicate anything.
When it comes to Griffith University findings I do think several other groups have tried to replicate the findings but failed. Most notably the recent intramural study looked at NK cells without finding anything. Davis also looked at NK cells I believe, so did this study and this study, Klimas wrote a review on NK cells in ME/CFS more than 20 years ago: https://www.sciencedirect.com/science/article/abs/pii/S1529104901000472. They also produced further studies on this subject, such as https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0010817. The differences may be due to methodologies differing (the NIH assessed NK cell function using a Chromium release assay within 24 h of collection of the blood) or not.
This could be huge or it could be nothing but without replication who can tell.
This is why I get so frustrated when people say there's currently nothing we could direct more funding at.
I usually feel similar. With this particular group, it appears they have gotten funding after funding for several years and they produce paper after paper. I would think that if they wanted others to investigate this, they'd probably just increase their sample size and improve their methodology (in the past there have been concerns about them not correcting for things, presenting no actual data, no statistical analysis, not presenting the full data etc), instead of publishing the same study over and over again and then arguably completely overhyping those papers with different quotes in the media.
