I heard that the Jets ran into some financial difficulties but have had some key supporters (eg Barossa winery moguls) come on board and now are quite well off. Money available for players/coaches. Heard a whisper that Matt Weaver from TTG may be in their sights but unsure if that is true.
Their indoor centre is no more but it's really only used for two months of the year. Not sure it was much of an income source. There's an indoor centre at Trinity College I imagine the Northern clubs will tap into now.
I'm unsure who these Barossa Winery moguls you speak of are? The jets have a player who personally and family wise run a $100million dollar business who are no longer sponsors anymore and haven't been sponsors for a few years now. I haven't heard of any other winery's nor have many others been involved in recent times.
I'd assume they would use Trinity's indoor centre, or possibly Mega Courts at Windsor Gardens who have a far superior set up.
