Alloy t-bars legality

I was wondering if anyone knows (for sure) if the alloy t-bars that fit on beetles instead of bumpers are illegal or not (in QLD).

I assume they are because of the potential safety problems if you hit a pedestrian, but they do look cool.

i know they are not allowed in NSW. but you still see them on the cars. they are probably just swapped for rego or if defected.
