Neither of those nations falls within Oceania. Hell, the Seychelles isn't even in the Pacific to begin with; it's in the Indian Ocean and considered a part of Africa.
The Philippines is just as much a part of Asia as Japan, Taiwan, and Indonesia are. Why people like to lump the Philippines in with the nations of Oceania, I'll never know; if you're going to do that, do the same to Japan, Taiwan, and Indonesia as well.
One thing I find downright bizarre is that Australia is no longer part of the Oceania Football Confederation; it left in 2006 to join the Asian Football Confederation for reasons that are completely beyond me. Soccer was never my strong suit.
