WATCH: Australia PM Accidentally Swears On National TV

Australian Prime Minister Scott Morrison accidentally swore on live television while he was delivering a speech over the weekend.

The prime minister was speaking to reporters in Adelaide Sunday to announce the federal government's injection of more than $1.6 billion to the city's North-South Corridor project when he said "s----y" instead of "city," News.com.au reported.

"This brings to completion the full financial commitment of the Commonwealth government to this s----y, city, ship, city-shaping," Morrison said.

"You’ve gotta be careful with that... I'm sure that'll get a run," the official added before he continued with his announcements, a report by 7News.com.au said.

One social media user reacted to Morrison's tongue twister by saying that they had "a 'city' Prime Minister," according to the outlet.

Another, meanwhile, defended Morrison and said that he was "only human."

Australia's federal government plans to commit AU$2.26 billion ($1.61 billion) to fund the River Torrens to Anzac Highway section of the 78-kilometer (48.5-mile) North-South Corridor, which will run through Adelaide's western and south-western suburbs, ABC reported.

A similar amount was announced last year for the section between Anzac Highway and Darlington, according to the outlet.

Overall, the government's total commitment to the AU$9.9 billion ($7 billion) North-South Corridor has risen to AU$6.8 billion ($4.8 billion). The rest of the funding will come from the government of the state of South Australia.

The project will see the construction of tunnels from Mile End to Torrensville and from Clovelly Park to Glandore, while avoiding the demolishment of heritage-listed buildings and splitting of neighborhoods in two.

However, hundreds of houses will have to be acquired to complete the freeway.

Morrison's blunder came days after people on social media mocked him for playing the ukulele while singing the New Zealand group Dragon's 1977 single "April Sun in Cuba" on the show "60 Minutes."

The ukulele's association with Hawaii resulted in people referencing the prime minister's decision to take his family on a holiday trip to the tropical destination as bushfires swept through multiple states in Australia.

"I think he learned that in Hawaii, didn’t he?" "Today" host Ally Langdon joked on the morning show as she introduced the clip of Morrison performing with his wife, Jenny Morrison, and their two daughters, Lily Morrison and Abbey Morrison.
