Fiji's connected to the Southern Cross cable, one of the main transit 
routes between Australia and the US, running from Sydney to Oahu/Hawaii. 
Plenty of capacity for a bit of island Starlink there.

It is in fact time that the world started thinking a bit about better 
connectivity in the Pacific islands. People like David Lassner from 
UHawaii have argued this for a really long time.

It's not just because of the locals. The Pacific is where your weather 
is made and where a lot of your fish comes from. It's where things 
happen at a big scale that are interesting to watch, from stars to 
volcanic eruptions, climate and so much more. Geopolitics play out here, 
often out of view.

But it's also because of the locals. It's a fascinating cultural space, 
too. Did you know that Tongans are part of the Polynesian family, and 
Polynesians can communicate with each other in their languages from NZ 
in the southwest to Hawaii in the north and Easter Island (Rapa Nui) in 
the western Pacific? Hawaii is a ten hour flight from New Zealand, but 
they knew how to navigate back and forth between these specks of land in 
a vast ocean for many centuries. Yet many Western countries don't as 
much as mention this in their school curricula, giving instead wide 
space to the vastly more compact Mediterranean or the not-quite-as-big 
Atlantic.

Nowadays, the Pacific is the scene of one of the world's trickiest and 
most cruel digital divides. Anyone chipping away at this is welcome.
