Asia - How do I get from Mindanao to Indonesia?

Once upon a time there was a flight from Davao to Manado. Now - no more apparently. Does anyone know how one can get to Indonesia from Mindanao without flying back up to Manila?

Thanks

I can't immediately see any easy routings on Expertflyer.

You could get the M.I.L.F. to take you across in a speedboat I guess! :D

(Edit: OI! Why is the Moro Islamic Liberation Front being censored here if you type it without the full stops?)
