How much do you get paid on the dole in Aust? (more info)?

I'm an 18year old(almost) and i'm planning to move out next year to Melbourne. I've had 2jobs I worked at a fast food for a year and my current job in retail. I'm not getting the amount of hours i'm after, if I am it's only $70 a week then the next week I won't have any hours. I have rent to pay and a phone bill which makes it really hard to save up. I've tried looking for a job but I can't seem to find anyone whom will hire me. Would I get more on the dole? How much roughly?
