The Australian Embassy in Lao is located in Vientiane close to the Mekong River and not to far away from the Thai Embassy in Laos and up the road from the Chinese Embassy as well. If you live in Laos or working in Laos then you can contact the Embassy for consular assistance if you have any problems.
They can also assist you with a birth registration and a public notary. Note that you can also contact them about your passport renewal or applying for a new passport again if you have lost yours or it has expired or is full. They can also assist you with applying for an Australian visa such as a partner visa, or a skills visa or even a student visa if you wish to study in Australia.
