I came across one very strange offering (admittedly not RTW, but cirlce) out of NAN (Fiji).
Fare Code: JAP6M on PR/AA/QF/CI/FJ Circle Pacific. $4880 AUD. This seems to be an old fare.

ZRWESC (VS/NZ) out of NAN is priced at AUD5500. So not too bad.


I have had trouble finding Australian pricing info about QF/LY fare, but will keep searching.
