Laws - Detailed View

To own a paintball marker you must be 18, have a shooters permit, then apply for a permit to purchase.
Once that has been accepted, a local district firearms inspector will come to where you intend on keeping the paintball marker to make sure that it kept in an appropriate safety cabinet.
A paintball marker can not be fired anywhere except a registered paintball field.

Joining a paintball club is an acceptable reason to apply for a license.

The Victorian Govenment has announced that they will lower the legal age to play Paintball to 18, but as yet have not given a date.
