Punishment for a drink driving charge?

I made the stupid mistake of getting arrested for drink driving on a camp site in Kalgoorlie at the weekend and I would like to know what the possible punishment is?My breath analysis reading came back as 0.19 which is almost 4 times the limit..I don't have any other driving related offences..Also I would like to know do I have to actually appear in court or can a solicitor represent me in my absence?I live in Perth and have no way of getting back to Kalgoorlie..I am not an Australian resident,I am a backpacker..I already know that I am a stupid idiot for what I did and don't need to be reminded of this..Any useful information will be greatly appreciated..Best answer for most information.
