Given there has been a few posts asking about airbags, with lots of wrong info being given out, i'll post the correct info for all to read..
No reason airbags can't be made legal..
Straight from the QLD Transport modification hand book....

Lowering or raising of vehicles
The road clearance of a fully laden vehicle must not be
less than 100mm measured at any part of the vehicle
other than the wheel rim or brake backing plates.
(This does not apply where a lesser clearance has been
specified by the manufacturer.)
When lowering or raising a vehicle body (front or rear),
the following additional restrictions are based on the
manufacturer's dimensions for the standard unmodified
vehicle while unladen:
• The ride height measured between the rubber bump
stop and the corresponding metal stop may be reduced
by no more than one third.
• The rebound travel measured between the rubber
rebound stop and the corresponding metal stop
(or the extension of the shock absorber for vehicles
without a rebound stop) may be reduced by no
more than one third.
• Coil springs are to remain in locating seats on full
suspension droop without forcibly being removed.
In addition, the normal relationship between the front
and rear suspension heights must not be unduly affected.
Replacement springs (shorter or taller) must have the
same or greater load capacity as the original springs.
Suspension coil springs must not be shortened by cutting
or heating. Leaf spring suspensions must not be raised
by the use of extended shackles, adjustable metal plates
or by placing the leaf springs to the opposite side of the
axle. If lowering blocks are used, they must be either
steel or aluminium.
Airbag or air pressurised shock absorber helper springs
may be fitted in addition to the original suspension.
However, replacing some or all of the suspension system
with an air or hydraulic suspension requires specific
approval.
You need a mod plate.. Thats all.... (And to comply with the rules)
Don't beleive me? Go have a read here :

Page 5 of the modifications guide.
They CAN & WILL Defect you if you have illegal suspension & chasis modifications, which is what a lot of people do when they install straight bags without getting the proper approvals & doing the job properly. But if you are willing to work with an approved engineer there is no reason that pure airbags could not be made legal..
The amount of bullcrap getting about reguarding modifications not being possible, not legal, or whatever is just amazing.. Do people even bother to read the modification guidelines? or even asking the guys who engineer & approve this stuff?
Some more light reading if your actually serious about doing airbags:
