As much as I'd love to see Campbelltown Stadium upgraded, with the way the economy is, I believe this sort of spending is reckless
Without side tracking this thread into a political discussion, I will have to say I disagree this would be reckless spending. In fact, there is probably an argument this is **exactly** the type of government spending that should be utilised.
Regardless of where the stadium is built, this is a relatively cheap infrastructure project that should produce positive returns for the economy reasonably quickly. Government bond yields are low and jobs will be created both in the construction of the stadium and the maintenance. Importantly, it will also mean the end of state government expenditure for other boutique grounds. This would also flow through to reduced pressure on councils expenditure of grounds (ie: they don't have to bring a suburban park up to standard for a national competition).
