Australian Tourist visa british father thai son with thai passport

[surfcrazy]

I plan to travel to Australia in April to surf with my 11 year old son for 9 days with out his mother. Plane tickets, accommodation, surfschool and food is already paid for.

I have a british passport and have applied online (today). My son has a Thai passport and because of the passport office being closed he will only get his passport next week. I understand I will have to apply seperatly for his visa and not online.

What forms etc do I need to get the Australian visa.

Note.

I am not married to his mother.

I am on his birth certiicate etc.

Is there a company who can do the application for us quickly without traveling to Bangkok.

Thanks

OP: The URL below will talk to the requirements also go to page 4 - Applicants under the age of 18. Visa processing times are from 10 working days to one month. Personal decision to use an agent, but I would not as it's just following a well documented process.
