All other Banks charge 150 baht to use their ATM machines but AEOM bank is free of charges to use a overseas ATM card. Where are their machines sited in Phuket? I know of 2 locations, one in Big C and 2 machines at their bank in Central Festival. I would like to know of a machine in Chalong saving me the trip into Big C or Central every time I want to use their machine.

Looks like that's it - searching only shows up those two.

No more on the whole island, that's it. 1 at big c, 2 at central.

I wonder what's the exchange rate offered by Aeon ?

At atm better than the other banks in my experience.
