Do you have problem to understand the question the OP asked: Lob + land base somewhere?Myself and two other divers are planning on Raja Amat on shore diving and 14 diving days with around 45 dives last week of September and first 2 weeks of October 2022. We can do some longer day trips for some far away areas but plan that after arrival. Night dives can be done on the house reef and no need for a guide.
I am flying in the morning from Taiwan to Jakarta arriving in the afternoon and taking the same night flight to Sorong which arrives early morning. There are ferries ( around 2 hours ) from Sorong to the island at 9am and 2pm where I am staying and will be diving with Soul Divers. My 2 buddies fly out from London and we all meet up in the airport in Jakarta. Air Asia to Sorong and back to Jakarta.
So our last diving day would be 36 hours before we fly back to Jakarta where we will stay a night and relax before flying home so our total trip time is around 17 days. We decided not to do a LOB and also not to dive other areas as we all like to not travel too much once we arrive in country.
If you are planning a trip that routes through Taiwan you need to be aware that tourists cannot enter Taiwan atm and I am not sure if you can transit here as well I will check on that but things will surely change later this year.
Currently rules are when I return to Taiwan I face a 10 day home isolation if I don't have active Covid.
What you do/don't or entry requirement to Republic of China are irrelevant in this thread. LOL.
