However, this appears to be incorrect - there is no town there named Gordon, certainly not one with 6000 residents.
The only significant "Gordon" in NSW is geoname 2164903, which is a suburb of Sydney. This has 7668 residents according to the last census (https://en.wikipedia.org/wiki/Gordon,_New_South_Wales). This point is not in the "cities over 1000 residents" data set.
I suggest that:
- Geoname 2164904 be changed to population=0, perhaps even feature_code=PPLH, and no longer included in cities1000.zip
- Geoname 2164903 be changed to population=7668, and be included in cities1000.zip
