Low Wx Minima Procedures and associated gear will be available when the airlines agree to pay in increased charges, which they won't.
Just a tad over 22 000 000 people went through BNE FY 14-15.
At 10 cents a head that's $2 200 000. Realistically you could charge $1 head and people would never know given the amount of tax/charges that is thrown upon this industry. And that would be a one off infrastructure tax for 12 months not an ongoing one.
Realistically you can fund anything in aviation relatively easily it's just all the BS politics and ideology gets in the way of sound decision making.
