Hello Fred,
The cost is minimal. For example the Sutherland shire re-lamps most fixtures
over about a 3 year period, whether they need it or not.
I get the impression I'm preaching to the converted here...we need better, not more lighting.
The USNO has a great page that covers many aspects here

Europe already glows in a sea of LPS yellow at night....it just takes Oz a few dozen years to catch up it seems.
Cheers
Peter
