Buried

Based on the environment and threats previously listed, no finish will last more than a few years. Given the high humidity, many thin coats of polyurethane or spar varnish, possibly with a drying accelerant, i would expect would be required based on my experience along the US Gulf coast. Expect to re-coat every few years. if there are surface oils on the rubber tree wood, a good wipe down with alcohol before applying finishes would be a good idea. An alternative would be a thinned coat or two of shellac as a base.

Wisebond clear self leveling epoxy finish for bars and same for floors https://www.wisebond.com/collections/bar-table-top-countertop-epoxy-resin

Take a look at clear epoxy used for bar tops and floors something like this https://www.homedepot.com/b/Paint-Interior-Paint-Countertop-Paint/WiseBond/N-5yc1vZc61sZq2k Also, consider an overlay of polycarbonate. I would not use acrylic sheet as it scratches too easily.
