As an occasional time-killer, I've been loading past season crowds into spreadsheets, using the full season draws here at LU as my guide. Don't know where I should raise this as a point of order, but all Storm's home games from 1998 to 2009 appear to be recorded as played at Olympic Park, Muswellbrook, rather than Olympic Park, Melbourne.
As an aside, I recently encountered this diabolical set of crowds from round 13, 2010 --
Bulldogs v Tigers at "Accor" (Fri 7.35) -- 11,837
Eels v Storm at Parra (Fri 7.35) -- 7,572
Panthers v Knights at Penrith (Sat 5.30) -- 10,969
Roosters v Sharks at SFS (Sat 7.30) -- 7,934
Raiders v Titans at Bruce (Sun 2.00) -- 10,425
Warriors v Dragons at Mt Smart (Sun 2.00) -- 8,312
Sea Eagles v Broncos at Brookvale (Sun 3.00) -- 11,316
Rabbitohs v Cowboys at "Accor" (Mon 7.00) -- 9,688
Total 78,053
Average 9,757 (season average crowd was 16.4k)
