The ACAPTA Accredited Busking Permit is for 'buskers that do involve dangerous materials or dangerous implements in their performance, carry a National Busking Accreditation Card and their own public liability Insurance': at cl 2.3.
In the Australian context, we note that ACAPTA's National Busking Accreditation Card is an attempt to reduce the regulatory burden on street performers who travel to different parts of the country: see Sydney Guidelines cl 3.3.
