I was able to withdraw 2.5 million three times in one visiti at ATMs in Bali Indonesia. Some ATM are marked 1.5 million only. AFAIK you can withdraw up to your daily limit from your banks atm card. Also when I was in Lombok as well.
I've never had my card scammed or taken by an ATM yet anywhere in the world.
I'm not as concerned about Bali as Sorong.
