There were numbers floated about way back when we moved from the SFS - The ANZ deal was 100k / Match... Rail, Hail or Shine - Win, lose or Draw.
I also heard from the CEO at the time that, We were lucky to be breaking even for the other grounds.
Cambo took care of everything - But we needed to get Close to 20k through the gate to make Money.
LO needs less through the gate to make money - But the club had to take care of everything - Traffic Control, Hiring the TV etc.
Not sure if any of the above is still the case, Or when the original ANZ deal ended (I had a feeling it was 10 years - Which would work with it finishing in the last few)
My guess now that the same guys own all the operational stadiums the Price they pay us to play there has decreased - Which would also lend itself to another reason we're moving back to LO and CSS.
