text: I see on satellite imagery that they may be slf contained cabins operated by the caravan park. 
  The tags used are 
  name=Theresa Dam Caravan Park
  source=survey
  survey=gps
  tourism=chalet 
  (tourism=chalet looks like the nearest tag to Aussie cabin accommodation at Caravan Parks)
  Do you think changing the name to "Theresa Dam Cabin Accommodation" would fix the problem.
