If you are in Bali for up to 30 days you get the Visa On Arrival as already mentioned.
If you are going for longer or a different reason than a holiday you need a different type of visa which you apply for before you leave.
Some info at the link below (assuming you are from Australia)
If not contact Indonesian consulate in your country for information
