Yeah there is also BBLANZ (

Also the Reddit one, The Big O (which is a part of ReBBL
http://andrewpgamba.wixsite.com/rebbl), might have some space if you wanted to throw a team in the deep end as a substitute team for ones that have dropped out mid-season. Otherwise the season there is almost finished (I think just 3 weeks remaining before playoffs), so they'll be taking new signups soon, and although the new season won't start until playoffs finish, once the regular season finishes they allow some "pre-season" games via their ladder to kinda prepare your team for the regular season.
If you do start your own Oceanic timezone league though, I'd potentially be interested.
