The big question for a potential stadium at Victoria Park is, what does it look like post Olympics?
If it's 55k or 60k for the Olympics, will it stay the same capacity after the Olympics? Is there a demand for a large oval stadium in Brisbane?
Every four years, there are two major test series, one against England, the other with India. ODI's are becoming less relevant except when the WC comes around. And what is the future of BBL?
Then you have the Lions in Fumbleball. Yes they did win, and may have a surge of popularity in the short term. But they can't win all of the time and there will be years where they will be at the lower half of the ladder.
Not sure there is enough content or demand for a large 55k oval venue in Brisbane.
Also by 2050, Brisbane's population is projected to be over 4 million, which is less than what Sydney has at the moment. As well as the SCG capacity is less than Victoria Park's potential capacity for the Olympics.
Meanwhile Suncorp has two NRL tenants, Magic Round, Kangaroos and SOO. And this is just rugby league alone.
