Legalisation of Thai birth certificate

[Jinjo14]

I need to get my wife’s Thai birth certificate legalised. We’re in Sydney.  What’s the best procedure to get it done? 
 

I already have a copy of the birth certificate and a certified  translation in English that has an expiration date 2020.  Probably useless now, who knew translations expired.

 

shall I get a new birth certificate from the amphur? Do I need to send someone in Bangkok to the Department of Consular affairs?  Get it legalised, and after translated again and sent by snail mail to Australia??  After I need to get it legalised again by the Thai consul in Sydney?? Is this the best albeit painful option??

This is what I gather from the email I got sent when I enquired at the Thai consulate in Sydney:

”

If the original Birth Certificate was issued in Thailand, the document must be legalised by the Legalisation Division of the Ministry of Foreign Affairs in Thailand before being legalized by Royal Thai Consulate-General.

 

The Royal Thai Consulate-General in Sydney can only certified true copy of Birth Certificate issued by the Royal Thai Government. (Original document requires for certification with certified true copy)”

 

thanks in advance to whoever chimes in.
