There are some pretty impressive facilities being developed, if you read the article... some are spending a lot more cash... probably in part as they have more government support. $19m was on the low end, but some include grandstands and more fields. The Eels are going to have four fields and a stand for their junior grade home ground, for example. The Raiders already own West Belconnen as well, of course, which can be used for that. The Sea Eagles are getting a new stand at the northern end of Brookvale with high performance facility built in. The Roosters are spending just $12m, but I think that integrates into the new SFS.
These are the spends:
Wests Tigers ($30 million), Canberra ($19 million), Cronulla ($23 million), Parramatta ($40 million), Manly ($33 million), South Sydney ($25 million), Sydney Roosters ($12 million), North Queensland ($40 million), St George Illawarra ($30 million)
