The Lapita culture developed on islands off the east coast of Papua
New Guinea around 3500 years ago. Approximately three hundred years
later the Lapita people started heading east to become the first
humans to settle the Solomon Islands, Vanuatu and Fiji, moving later
to Samoa and Tonga.

, it looks like they spread was from west to east , and this clashes
with the out of Asia origins . IMHO a Canaanite Phoenician trader
origin fits better , they carried dogs onboard and the australian
dingo arrived about that time , see wiki , "it was regarded as most
likely that dingoes arrived in Australia about 4,600 to 5,400 years
ago, which was consistent with archaeological findings" , . The
recent Lapita discoveries in PNG , were very close in time and
distance , from the famous spice islands , see wiki " cloves grew
only on a few islands in the Maluku Islands (historically called the
Spice Islands), including Bacan, Makian, Moti, Ternate, and Tidore.
[13] Nevertheless, they found their way west to the Middle East and
Europe well before the 1st century AD. Archeologists found cloves
within a ceramic vessel in Syria along with evidence dating the find
to within a few years of 1721 BC. " , Trade by Canaanite /
Phoenicians sailors directly to the east via red sea , was ended by
the bronze age collapse , and then by other traders networks served
the Persian Greek roman then Arab empires before recent European
traders arrived . IMHO a very good case can be made to support a
Canaanite traders " origin " of the early lapita pottery , ending
with the bronze age collapse cutting off all contact suddenly about
3000 odd years ago.
