eBay advises the following regarding purchasing from sellers in Thailand and India:
 
As you are most likely aware, protests in Thailand have led to the temporary closure of both of Bangkok's International Airports, while Mumbai, India last week suffered terrorist attacks.

If you have recently purchased item(s) from sellers in Thailand or India, please be patient and understand that there may be delays in communication and items being shipped to Australia.

Regards,
The eBay team
