A prescribed temporary structure is defined by the Building Regulations 2006.
Regulation 1104 defines ‘prescribed temporary structures’ if those structures do not form part of any other building other than a temporary structure or temporary building as:

If the building is a prescribed temporary structure, as defined by the Building Regulations 2006, a building permit for its construction is not required, however an Occupancy Permit from the Victorian Building Authority (VBA) and a siting approval from the relevant Municipal Building Surveyor will be required.

Section 23 of the Disability Discrimination Act (DDA) prohibits disability discrimination in relation to the access to premises that can be accessed by a section of the public, irrespective to whether a building permit is required for the structure. However, the disability access to premises standards made under Section 31 of the DDA state that compliance with the standards ensures access is provided for people with disabilities to buildings and where compliance is achieved, discrimination does not occur.
The VBA is not required to address access for people with disabilities as the temporary structure does not require an approval for its construction, which is a trigger under the disability access to premises standards . However, the VBA has in the past and still may require a level of access to prescribed temporary structures it approved for occupancy, with the view of mitigating any possible discrimination to a certain section of the community as part of its duty of care. Questions relating to conditions on Occupancy Permits for prescribed temporary structures may be directed to the Team Leader in the Technical and Regulation Department of the VBA.
