Townsville will be playing NBL this season.
The Advertiser reported this 3 weeks ago (April 24):
"Holmes' Crocs were saved on Thursday when creditors confirmed their acceptance of a new deal, which means a club restructure. But Townsville lives on."
As yet, though, I haven't seen an announcement about this on the NBL site nor on the Townsville Crocs' site. They have put stuff on there about the move back to The Swamp for 2015-16.
As per Gongski's post above, Wollongong have yet to present a plan acceptable to creditors. The deadline for that is ~24 May, if I remember correctly. That's based on the reported outcome of the creditors' meeting on 10 April where a 45 day extension was given. If I've got the dates wrong, happy to be corrected. There's a report on that 10 April meeting on the NBL website, in the news items.
