Hundreds of Sydneysiders voted for the name in a public competition, with NSW Public Transport revealing the official title on social media overnight.
Boaty McBoatface topped the competition's standings, but in a game punt for originality New South Wales Public Transport opted for second place - the inspired Ferry McFerryface.
The new inner harbour ferries are being delivered as part of the NSW Government's plan to modernise and expand Sydney's ferry network. "This one is for the kids". The same name the British chose.
"Given Boaty was already taken by another vessel, we've gone with the next most popular name nominated by Sydneysiders", Mr Constance said, no doubt using the word "vessel" in an attempt to add nobility to what is a ridiculous situation.
The name is a variation on a joke that began with a similar competition for a British research vessel previous year.
Here's to hoping Ferry McFerryface lives a longer life along the waters of Sydney Harbour.
Three of the new ferries have already been named by the public, paying homage to notable Australians Victor Chang, Fred Hollows and Catherine Hamlin.
The Boaty McBoatface legacy has spread worldwide, with an express train in Sweden named Trainy McTrainface earlier this year and a team at Sydney's Warwick Farm racecourse naming their horse Horsey McHorseface last year.
Sydney, home of Australia's busy ferry fleet, is getting a new addition and the name of the new vessel will likely keep its passengers smiling during every trip it makes.
