Average windspeed at Tennant Creek looks a bit marginal, [ 5m/s ], but it's ok.
'Geothermal', [ and included in this term I mean collection/dispersal of energy by heat-pump from shallow collectors for domestic heating/AC ], could be additional to and not a choice alternative to wind turbines. If he means deep-bore collection hot enough to run a turbine-generator plant, the site is not likely to be suitable for both technologies unless the facility got really lucky.
This demolishes the objector's comments.
Besides which, I think bladed turbines will be superceded by bladeless designs in very quick order. Quiet and with little risk to birdlife.
If you would like to see how this might be done, Gooogle "Tesla's turbine". Yep, it's 'Mr. 3-phase' himself, the one and only, patenting a turbine with no blades AT ALL!
