Can my employee correct a typo on his e-visa while in Thailand instead of returning to Sydney?

An employee facing a typo issue on their e-visa from the Thai embassy in Sydney must determine if corrections can be made without returning to Australia. Currently, the BOI is not allowing further visa applications due to this typo, and the embassy advised that the e-visa needs to be corrected directly in Sydney. One suggestion is to consult the Sydney Embassy to see if they can process the correction while he is still in Thailand.
