It reads as a bit of remark of what the future might hold. Indeed it seems a logical next/future step. At some point it would make sense to redevelop Memorial Drive into a multipurpose stadium.
I think it would be a good idea having a 12,000 seat venue, 18,000 seems a bit much. Atleast with that figure, it's around the size of Hisense, would work for any Tennis tournament we can attract, would work for international netball and netball finals, and the 36ers. It would share the overall costs which makes sense, and being in the city, it would hopefully attract more people to games (from the 36ers perspective) then before.
If I remember correctly, the minister said any potential funding couldn't be done now, but maybe around 2019/2020.
In terms of the State being "broke" or whatever, I'm not saying we can fund many major projects at once, or that we can spend spend spend, but a good government will properly understand the situation and make measured responses.
I love it when people argue with confidence something along the lines of "debt/interest repaymants=spending too much and therefore we're in big trouble".
That's not how it works. People don't realise this, but it's not relatable at all to the finances of a household. Surplus/Debt are part of the cogs in the economy, but it's not a dominating or prominent part of the financial performance/position of an economy. An economy in debt could just as easily be in a financially strong position than an economy in surplus. Purchasing power, growth, the cash rate and employment rates are all important cogs that should be mentioned along with debt (and potentially even more prominently).
A straight out argument of debt/interest repayments is an over simplification that does not reflect reality. If anyone is intent on using it as an argument with some sort of reflection of economics, it needs to be tempered with context of other cogs. For lack of doing that, people might as well not bother arguing it all together.
