Can I get an entry stamp for my emergency passport at the airport in Thailand?

A user in Thailand with an emergency Australian passport is seeking clarification on whether they can obtain an entry stamp directly at the airport or if they must visit the Thai immigration head office. Comments indicate that if the user has an existing tourism extension, they must go to the specific immigration office that issued it to transfer the stamp. If they only have an entry stamp and no extension applied, they can exit with both their old and new passports.
