another invalid location! Kowen, in the ACT
another invalid location: Defence HQ in the ACT
another invalid location: apparently no one lives in Belconnen?
invalid locations: Weston Creek and Stromlo in the ACT
another invalid location: Tuggeranong - SSD Bal

I conclude that the location data are weird, because Tuggeranong has
lots of people!
also an invalid location: Fyshwick in the ACT, despite being populated!
also invalid: Harman in the ACT
