Here the link to the RWC COP,
The links are for sections 2 and 3, section 1 is for administration guide lines.
If after you read through them you have any questions, as an approved inspector I am happy to give you advice based on my interpretation of the section of code in question. (my self and 4x4play will not be held accountable for any losses, issues ect encountered by following the advice given)

the next link is a PDF version of the modifications booklet available from QLD transport.
It contains enough information about wheel, tyre and suspension modifications to keep you pointed in the right direction. There is no vehicle specific information in the booklet, You will to research the standard measurements and options for you 4x4 and apply the rules to that info.

The light vehicles modifications code of practice
IS NOW AVAILABLE AS A FREE DOWNLOAD
http://tmr.qld.gov.au/~/media/safety/vehicle-standards-and-modifications/vehicle-modifications/light-vehicle-modifications/codeofpracticelightvehiclesreductions.pdf
Just to %100 clarify suspension mods.
here is the wording of the code.
Suspension modifications to light vehicles (under 4.5 t GVM) with a separate chassis are
permitted under Vehicle Standards Bulletin No.6 ? Heavy Vehicle Modifications. However, no
deviation from this code is permitted unless specifically authorised by Queensland Transport.
and here is VSB 6

This is what most people have been asking, Can i fit a 2 inch body lift AND a suspensions lift.
AIS INFORMATION SHEET No. 18
FITTING OF BODY LIFT KITS AND SUSPENSION
HEIGHT MODIFICATIONS TO MOTOR VEHICLES
A number of queries have been received by Queensland Transport in relation to the
permissible maximum heights that a motor vehicle can be raised.
Body Lift Kits
The maximum allowable height increase permitted by Queensland Transport has been set at
50 millimetres (2 inches).
Suspension Height Modifications
The suspension travel in the bump or rebound mode must not be altered by more than onethird
of that measurement as specified by the original manufacturer.
These limits have been set after taking into consideration the following aspects of
modifications of this type:
? stability characteristics of the vehicle;
? strength of componentry being utilised;
? the road holding ability and handling characteristics of the modified vehicle;
? braking characteristics of the modified vehicle; and
? the wheels and tyres fitted to this vehicle must comply with the requirements of the
Transport Operations (Road Use Management - Vehicle Standards and Safety)
Regulation 1999.
It should be noted that both modifications can be performed simultaneously to a vehicle to
gain extra vehicle body height but individual specifications must not be exceeded.
Modifiers may have to obtain the original bump stop clearance to calculate the allowable acceptable
increase.
A policy in relation to this matter has now been finalised and will require:
? An individual vehicle modification application to be made to Queensland Transport for
body lift kits (blocks between body/cabin and chassis mounts) up to 50 mm in
height. Applications must indicate all changes being made to implement the
modification (including steering and braking componentry) and materials used in the
lifting blocks. Body lifts in excess of 50 mm will not be considered.
If acceptable, a letter of approval for the installation of a body lift kit will be issued by
Queensland Transport.
? Suspension height modifications carried out in accordance with good engineering
practice will be considered acceptable where the suspension travel in the bump or
rebound mode is not altered by more than one-third of that measurement as specified
by the original manufacturer. A vehicle modification application will not be required.
This onus is on the modifier/owner of the modified vehicle to ensure these standards are
satisfied.
Modifications where leaf springs are remounted from under axle to over axle are not
regarded as an acceptable form of suspension modification and will not be approved.
The vehicle modifier is responsible for ensuring that the vehicle is modified in accordance
with relevant standards and recognized automotive practice.
Please Note:
If, at the time of inspection, any vehicles display signs of non compliance with these
standards, the vehicle is to be rejected. The vehicle owner/operator can be directed to have
the installation comply with the required standard and/or obtain relevant approval
documentation.
TIRES
no such thing as engineering larger tires in QLD, It' plus 15mm diameter no exceptions.
This next bit is GQ patrol specific:
Will also be usefull for any other 4x4 that has the option of running a 750R16 tire
33KM2s are legal on a technicality. and you would have to have the info on hand to get it past.
BF list them as 826mm (32.5inch) tall
750R16 is the tallest stock tire,
Yokohamas Y735b light truck tire in the 750R16 size is listed as being 812mm. So the KM2 in a 33 is only 14mm over, making it legal.
