As Steve (Slowy) points out, there is clearly no standard approach across the country to ICV approvals and the same applies to modifications. While there are ADRs and national standards, there appears to be nothing to ensure all states and territories adopt any of these. Honestly, I don’t see this changing in the near future.
In searching around, I found this reference on boostcruising.

I know it is not a definitive source of fact but it does provide some good information and references, particularly the National Code of Practice for Light Vehicle Construction and Modification (Feb 2006):
http://www.infrastructure.gov.au/roa.../vsb_ncop.aspx
There are a number of documents on this page relating to construction and modification of Light Vehicles (even a few specifically relating to ICVs). Specifically, the document below includes information about supercharging and turbo charging (modification code LA3) – see page 22.
http://www.infrastructure.gov.au/roa...s_3Feb2006.pdf
The requirements outlined are basically compliance with ADRs for emissions and exhaust noise as well as heat shielding, modified bonnets and drive belts. There are also some requirements around Mandatory Upgraded Safety Equipment (including requirements for Seatbelts, Windscreen wipers, Demister, Rear vision mirror … ?!?!?!?!).
Queensland Transport also has some documentation about Light Vehicle Modifications in this document:
http://www.transport.qld.gov.au/reso..._vehicles2.pdf
Superchargers and turbochargers fit into the Complex category and require approval from either Queensland Transport or an Approved Person (p23). On p24, “The minimum tandards for all of these modifications are contained in the Code of Practice – Light Motor Vehicle Modifications.” This information can be found on this page:
http://www.transport.qld.gov.au/Home...ractice/#light
In particular this document:
http://www.transport.qld.gov.au/reso...n2_feb2004.pdf
which outlines reasons for rejection of modifications. Unfortunately, there is little or no reference to any ‘minimum standards’ relating to supercharging in this document.
It is worth pointing out that many of these documents include a disclaimer that the information included cannot be used as a point of law. Note also that these documents are dated. There is no way to tell whether or not these have been superseded with others.
So, given the inconsistent approach across the country and the vague documentation provided by QT, I reckon the KB supercharger would easily be approved by an ‘Approved Person’. If it approved, then it should be OK. If no approval exists and the vehicle is questioned …??$?$?$??
The boostcruising post also refers to a QT Modification Hotline (32534851), which I will ring later this morning to ask who might be able to approve engine mods (heads, cam, supercharger) and I will let you know how it goes.
From everything I have read, have an authorisation from an ‘Approved Person’ (not necessarily an engineer) for any ‘modification’ would be the way to go.
My 2.2c.
