Australian basketball (NBL) underachieves when it comes to media and news attention. It's token at best. Adelaide is lucky to have Boti Nagy although it is unfortunate his space and frequency in the paper version of The Advertiser has diminished over the years.
The NBA tends to receive almost as much particularly with so many Aussies playing relatively prominent roles in the NBA these days.
But The Guardian Australia isn't a huge powerhouse like News Corp with local journalists in each city, so it is understandable in the competitive sports market landscape that they go with the basics of AFL/NRL/Cricket/A-League first, key events second, unique high/lowlights third and then other sports coverage last if at all. It's not really the site you go to for local Adelaide news, or for non-major powerhouse sports news. It's really only good for national news and politics.
It's a bit sobering for the NBL, I guess...Something to work on and aspire to.
