Firstly, Brian, my thanks to your wife for her comment.
As regards comparative weather between Ireland and the Philippines, I am at a similar loss to you as I have no experience of tropical humidity. From here-say, I understand that the humidity is somewhat different here. We can get prolonged rainy spells, generally cold with it. But it never really seems to be a problem for cameras provided they are protected reasonably during use and stored indoors in a dry warm atmosphere. I am told that the warm humidity you experience is somewhat different as it gets everywhere. Is this the case?
I honestly think you should not be deterred however. After all the Stylus 1 is a fixed lens camera and therefore not exposed to the dampness and dust risks associated with lens changes. It is very small, but seems to be built like a tank which for me is reminiscent of Olympus film SLR's of which I owned several over the years. The main body material is Magnesium, I think?
Have a look at this very comprehensive review by the Imaging Resource team. It's pretty well balanced.

Also three more considered samples which I took last year with the Stylus 1.
