We look forward to seeing your awesome costume! Unfortunately we cannot pre-approve cosplay props. Please visit our props policy on our website here: https://ozcomiccon.com/cosplay/policies/prop-policy/. If you are still unsure after reading through those specifications, please see our staff at the Props Inspection Booth onsite at the show and they will be able to confirm this for you. If your prop is acceptable, they can tag it so you can bring it on to the show floor; and if not, we can store it in our cloakroom for you for the remainder of the show.
