If we project that motion, the left shoulder of Australia gets caught, and then Australia rotates and collides against Borneo and south China — much as India did 50 million years ago — and gets added to Asia. However, due to a lack of data on the time required to produce flood basalts, the climatic impact is difficult to quantify.
