How does tourism benefit. Thailand is a poor country with little to offer. The average daily wage is well below Australia which is a very expensive country in comparison.
And again trade, Australia is resource rich in minerals they really need to focus on producing there own goods and products. Doing business with a corrupt country like Thailand has little to offer and lastly defence is the very worst idea. Asean is heavily in hock to china and Russia our enemies here in the west. I see no good coming out of it
