Can you play WoW overseas?

Hi everyone,

I currently live in Australia and I'm going to take a business trip around Asia for about 4 weeks, traveling to a few countries in South-east Asia and East Asia like Indonesia, Singapore, Malaysia, China, Japan and South Korea. I currently play WoW from my laptop and I need to bring my laptop with me on my trip. Is it alright to play WoW overseas because I've heard that Blizz can ban accounts if they detect it being played from another country different to where to original account's registered address is stated?

Appreciate any advice.
