In this case they are. Separated from others in the genus except carinata by it's distinct bluish-grey eye. M. bredli has less rugose scalation than carinata. Known from the Atherton Tableland and nearby areas of North-east Queensland. These snakes rarely exceed two and a half metres.
Adults are usually slightly less than two metres.
They are often characterised by contrasting yellow and black markings. They are characterised by an imbricate pattern, hence their scientific name. They also occur on some islands off the SA coast. This is the 'Coastal Carpet' from northern NSW and south-east Queensland. This is perhaps the largest of the Carpets with specimens in excess of 3 metres fairly common.
