I have looked on Fold 3 and it is just the medal card with the service number you have given coming up, same on FMP Quite a few Joseph Bennetts, do you have year of birth, any addresses or other criteria that could be used to see if any of the other records might be your man.
Ancestry has the Service Medal Roll's and they show 8 R. IrR Fus Pte
7/8 R. Ir Fus
1 R. Ir Fus
That is all I can find on details given
