If I recall correctly they are ilegal in some states

Think it may fall under 'adult' material ?? As in 'NO' 😮

Yes, they are illegal in Queensland. My friends owned an adult shop and could only sell ones that did not require a key and could easily be unlatched.

but the quick release ones should be OK... just appeal to T&S

There are plenty listed: http://www.ebay.com.au/sch/i.html?_trksid=m570.l1313&_nkw=fluffy+handcuffs&_sacat=0&_from=R40

That's correct for all of Australia.

For restraints needed is a  Security / Police / Defence / Corrections licence with the appropriate classes.

just re word it  with out adult play 

you can sell vibs on here and any adult stuff  just work it right so its not flagged

Only for the real police ones.. The ones the OP is talking about have a safety latch for quick release.. 

I can't see why you couldn't, you can buy leather restraints on here and plenty of other fetish type stuff is listed..
