Got a DUI in California driving on my australian drivers licence. What r the consequences & can i lose my Lic.?

Got a DUI in California. I am driving legally with my australian licence. I do however have a california drivers permit which just means i have done the written exam and not the driving test. What are now the consequences even driving on my australian licence? Can my out of country licence be taken off me? Should i get a lawyer? I am a student here and have very little money..
