The new NBL Live app has certainly been very well-received by fans everywhere, and it's been mentioned before by NBL operations manager, Guy Neville that streaming would be free for the first week.
The wait is over. Details of the new NBL Live subscription package are finally available at nbl.com.au/live, and the prices are certainly very competitive, with all game replays of this season included.
According to the site:
A season package is priced at $60, or 50 cents per game.
Monthly subscriptions on the other hand, are $15 per month.
The iOS version has indicated that its latest version 1.0.1 has "NBL Live Subscription integration".
Right now, the Android app does not seem to have any gateway limiting access to live games, but expect that to change very soon, likely with the next app update.
