No-one will come right out and say it, but the Wollongong Hawks seem certain to survive their third near-death experience in seven years.

Since being placed into voluntary administration two months ago, the Hawks' search for sponsorship has received a positive response from the Illawarra business community.

The NBL gave another strong indication on Wednesday the league's lone foundation club was on the verge of sorting out its financial problems by further delaying the start of the free agency period until May 15.

The similarly troubled Townsville Crocodiles are also reportedly close to confirming new sponsorship, all but ensuring the 2015-16 season will feature the same eight teams from last season.

Prospects of a Brisbane franchise joining the league in the near future are slim.

NBL chairman Graeme Wade said the continued freeze on player movement was designed to "assist the two regional teams".

"Townsville and Wollongong have received fantastic support from their local communities, fans and sponsors," Wade said.

"With the assistance of the NBL, both clubs are on the cusp of a definitive announcement about their participation next season."

Last month the Hawks scored a huge boost when they secured Multi Civil & Rail as their new major sponsor.

Hawks general manager Kim Welch welcomed the extended hold on the free agency period.

"It not only gives the players the opportunity to secure the best possible contract for themselves individually but allows the club further time to ensure it is also in the best position if and when we go forward," Welch said.

He went on to say he remains confident the club can secure its future in the NBL. The Hawks pulled through two highly publicised battles for survival in 2008 and '09.

Wade said Brisbane's entry into the league depended on finding a suitable home venue.

''It is unfortunate that there is not a venue of the appropriate standard to accommodate an NBL team,'' he said.

''The league is not prepared to risk the long-term viability of a club by using unsuitable venues.''
