This might assist or hamper any Australians wanting to get a embassy letter once the amnesty is over .This was emailed to everyone who is registered with the Australian embassy ( my apologies if it was posted earlier.)
Visa Letters:
Given how difficult it is to secure a flight to Australia, the Embassy has decided to assist in issuing letters to support people applying to extend their Thai visas. It is not the role of the Australian Government to be saying who should or shouldn’t stay in Thailand, that’s up to Thai Immigration; however, given Thai officials are reluctant to make these decisions without our involvement, we have decided to issue the letters for two categories of Australians:
1. If you are transitioning from a short term tourist visa to a long term visa, Thai Immigration generally want a letter from us to allow you to do so. We are happy to do so as long as you can show us evidence that you’ve applied for a long term visa; or
2. If you have had flights booked and cancelled, your next flight is after 26 September and you can show us evidence of this, we will also provide you with a letter to support your visa extension.
If you meet one of these categories please email consular.bangkok@dfat.gov.au, provide us with the evidence requested above and a copy of your Australian passport details page.
