Sydney's adoption of Ferry McFerryface as the name of its newest harbour-going vessel hasn't tickled everybody's funnybone, with claims the name is a mockery.

Paul Garrett, the assistant secretary of the Sydney branch of the Maritime Union of Australia, registered his anger over the issue on 2GB this morning.

"For the first time you and the MUA seem to be on the same page about this stupid Ferry McFerryface," he told host Ray Hadley.

"The Transport Minister is demonstrating here that he treats public transport as a joke."

"Ferry McFerryface" will be the latest ferry in Sydney harbour.

Mr Garrett said ferry workers were frustrated with the name.

"We're wondering why Sydney Harbour has to suffer a second-hand joke from the UK," he said.

He said staff would refuse to work on the ferry.

Hadley agreed, claiming even Transport Minister Andrew Constance's colleagues thought the pick was a "gee-up" at first.

Ferry McFerryface will join the latest batch of Sydney ferries, many of which were named after beloved Australian medical icons including late heart surgeon Victor Chang, late ophthalmologist Fred Hollows and obstetrician and gynaecologist Catherine Hamlin.

The name which actually received the most votes in the poll was Boaty McBoatface, which the panel overruled as they believed it was already the name of a British vessel.
