Here's the info I found a little while ago from the QLD dept of transport, but just in case you should find out current or any new info Please note:
"The contents of this publication are a guide only and cannot
be used as a reference to a point of law."
For a detailed explanation, refer to the Transport Operations (Road Use Management - Vehicle Standards and Safety) Regulation 1999.

Queensland Transport Customer Service Centre or

It is common practice for manufacturers to fit low profile tyres
to high performance motor vehicles as standard equipment.
Low profile tyres (50, 60 or 65 series), replacing standard
profile tyres (70 series or above), are normally fitted in
combination with rims of larger than standard diameter to
maintain the correct overall diameter of the wheel.
The rim diameter may be varied from the standard size
but the overall diameter of the tyre must not vary by more
than +15 mm or -26 mm.
These limits have been set for a number of reasons. Varying
the overall diameter of tyres affects ground clearance, centre
of gravity, brake effectiveness, steering geometry,
performance and speedometer accuracy.
Generally, to meet these limits, 60 series tyres are fitted to rims with a diameter increase of 26 mm larger than standard and
50 series tyres are fitted to rims with a diameter 50 mm
larger than standard.
General Conditions for
Alternative Rims and Tyres
The rims and tyres must not protrude beyond the bodywork
of the vehicle, including flares, when viewed from above and
when the wheels are facing straight ahead. If the vehicle was
originally constructed with a portion of the wheel protruding,
the wheels must not protrude further than originally constructed.
LOW PROFILE TYRE STANDARD TYRE
16
The tyre to rim fitting and the tyre to rim combination must
be in accordance with the Tyre and Rim Standards Manual
published by the Tyre and Rim Association of Australia.
Reputable tyre retailers should have this information
and be able to advise on the correct combinations.
All rims fitted to an axle must be of the same diameter, width
and offset. They must not have a circumferential weld other
than that which attaches the outer rim to the centre.
All rims must have stud hole pitch circle diameters appropriate
to the hub. Wheel nut tapers must be appropriate to the wheel
and must engage the thread of the wheel studs for at least the
same length as the nuts provided by the vehicle manufacturer.
Slotted and elongated stud holes are not permitted.
The fitting of spacers between wheels and hubs, additional to
those provided by the vehicle manufacturer, is not permitted.
The tyre and rim must not foul wheel arches or suspension
components under any conditions. Steering limit stops should
not be adjusted to reduce the turning circle in order to allow
the fitting of the tyres and rims.
The tyres must have a tread depth of at least 1.5 mm on every
part of the tyre that touches the road and not have any
apparent defect that is likely to make the vehicle to which
they are fitted unsafe. It is not permitted to fit tyres that have
been treated by recutting or regrooving unless the tyre has
been marked by the original manufacturer as “suitable for
recutting or regrooving”.
Tyres
The maximum tyre width must not be more than 1.3 times wider
than the vehicle manufacturer’s widest optional tyre. However, in
the case of off-road passenger vehicles fitted with front and rear
beam axles, the maximum tyre width must not be more than
1.5 times larger than the manufacturer’s widest optional tyre.
The nominal width of the narrowest tyre fitted to a vehicle must
not be less than 70 percent of the nominal width of the largest
tyre fitted and never less than the vehicle manufacturer’s
narrowest optional tyre as indicated on the manufacturer’s
tyre placard.
17
Speed and Load Ratings
The speed rating of all tyres must be:
(a) a speed of at least:
(i) for an off-road passenger vehicle - 140km/h; or
(ii) for another car (sedan, station wagon etc.) up to 9 adult
seating positions or a car derivative - 180km/h; or
(iii) for another motor vehicle - 120km/h; or
(b) the vehicle’s top speed, if lower.
Load ratings of tyres must be at least equal to those specified
by the manufacturer on the tyre placard fitted to vehicles made
after 1972. For other vehicles, the load rating of a tyre must
be capable of carrying the part of the vehicle’s gross mass
carried by the tyre.
Tyre Construction
Tyre thread compounds, patterns, ply ratings and performance
characteristics vary. Tyre construction (e.g. radial) and size must
be the same on the same axle. Although it is recommended
that the tyres are identical (i.e. same brand and tread pattern),
this is not mandatory.
Vehicle Track
Track is measured at ground level from the centre of the tyre
on one side to the centre of the corresponding tyre on the
opposite side of the vehicle. Front and rear track differs on
many vehicles.
18
The wheel track must not be reduced to less than the standard
track specified by the vehicle manufacturer for the particular
model of vehicle.
The track of a car or car derivative may be increased by up to
26 mm beyond the maximum specified by the vehicle
manufacturer for the particular model of vehicle. Off-road
passenger vehicles fitted with front and rear beam axles,
may have an increase in track up to 50 mm beyond the
maximum specified by the vehicle manufacturer for the
particular model of vehicle.
Wheel Marking
Vehicles built on or after 1 July 1985 must be fitted with
original wheels or replacement wheels which are indelibly
marked in accordance with approved standards.
These include:
• Standards Australia;
• Wheel Industries Association (Australia);
• Technischer Uberwachungen Verein; and
• Japanese Industrial Standards.
Markings must include diameter, width, offset and the
manufacturer’s trade mark or logo and be located so that
they are readily visible when the wheel is correctly installed
on the vehicle.
Composite Wheels
The use of composite wheels (two or three-piece) is
permitted. They must be manufactured and marked in
accordance with the standards described above if fitted
to vehicles manufactured after 1 July 1985.
Hopes this helps a bit guys.

To make that clear to everyone, you can legaly put 20" Rims on your fully sik lancer as long as the tyre+wheel diameter does not vary by more than +15 mm or -26 mm of the stock wheel and tyre. INSURANCE is the only limiting fact. 
Hmm max wheel width I can go on the Supra legaly is 292 then Looks like some 285s are the go then.
