Port Lincoln has a population of 10,000, and the next big town is 30,000 at Whyalla 3 hours away.
Adelaide is 6 hours by road, or one hour by air on a small plane.
Lots of money (as noted above) due to tuna.
Not a lot of rainfall, and a summer drought.
No local water resource, and any bore water is under pressure.
Getting water to irrigate the course for perhaps 7 months of the year will be a key issue.
Getting enough rounds played to make the course viable will be another.
Very pretty spot, and nearby Coffin Bay is idyllic, especially if you love Oysters.
