Santa Barbara, California -> Hilo, Hawaii 2067nm
Hilo -> Apia, Samoa - 2241nm
Apia -> Sydney, Australia - 2335nm
If the range is a problem then due to the Jetstreams, (although by now they should be well south of Australia )
Hilo -> Cassidy PLCH - 1068nm
Cassidy -> Nadi, Fiji - 1902nm
Nadi -> Sydney - 1712nm
There used to be a really good routing website, but I can’t find it anymore.
