Adam Marshall twice called Nationals Federal colleague Barnaby Joyce "a goose" in NSW Parliament last week.
The Nationals MP and Cabinet Minister interjected twice into an address by Labor MP Janelle Saffin to insult his Federal colleague.
The Labor MP for Lismore told parliament that high-profile former Deputy Prime Minister Barnaby Joyce had caused "some consternation in the local community" by holding his own opening of a new Tabulam bridge.
The upgrade recevied no federal money and was not in his electorate, she said.
After Mr Joyce used a red ribbon and scissors to conduct the unofficial opening, Ms Saffin told NSW Parliament the community were concerned the bridge may never get a proper opening including members of the community.
"I have sought assurances from the NSW Minister for Regional Transport and Roads on three matters: first, that this event was not official; secondly, that there will be an official opening; and, thirdly, that the community will be invited to celebrate. I have received those assurances," she said.
Member for Northern Tablelands Adam Marshall interjected, calling out "Barnaby is a goose".
"I note that the Minister for Agriculture and Western New South Wales said some words about Barnaby, which I may not repeat," Ms Saffin said.
Mr Marshall, whose whose electorate of Northern Tablelands used to include Tenterfield, interjected again.
"I said he was a goose," Mr Marshall said.
"He said Barnaby is a goose. So it will be in Hansard," Ms Saffin said.
In a light-hearted video posted on Facebook last week, Mr Joyce said he was opening the bridge to help out the state government, so they "didn't have to worry about it".
Ms Saffin didn't see the funny side.
The old Tabulam bridge the new one replaced is the longest single-span wooden bridge in the Southern Hemisphere, crossing the Clarence River to join the Bruxner Highway, she said.
It was completed in 1903 and could be destroyed after the opening of the new one, which is set to be formally opened at the end of September. The bridge has been delisted from the State Heritage Register.
The Tabulam community fought hard to save the historic bridge the new one replaced, the Ms Saffin said
The Labor MP said it is "emotional and a kick in the guts" to think the old bridge could be lost. The structure is a "sacred space" to the local Indigenous population, because many Indigenous people were born under it, she said
"I have not met a Tabulam local who does not want to save the bridge," Ms Saffin said.
