There were some fibreglass ones being made in Sydney ( IIRC ) but apparently color, quality and fit was very variable. Seem to have disappeared.
I've seen one of the initial ones fitted and honestly it just looked too big and chunky for the A pillar... didn't fit in at all. Looked DIY and tacked on.
Obviously with anything from the US you need to ensure its for RHD not LHD unless you want the passengers to keep an eye on things
