In fact, the wall has already been constructed, at Staverton tourist attraction Tasmazia and the Village of Lower Crackpot, south-west of Sheffield.

And it won’t be the Mexicans who pay for it.

“The Laird of Lower Crackpot got stuck with the bill,” Laird and Tasmazia developer Brian Inder admitted.

The Tasmazia complex includes an embassy garden, which has “embassies” of various countries.

It so happens, the US embassy (based on the Statue of Liberty) is next to the new Mexican embassy (a cactus).

President Trump’s election campaign was partly based on erecting a huge wall between the southern US and Mexico and making Mexico pay for it, in a bid to control the border.

Those two facts turned on a light globe at Staverton.

“So, with the advent of the creation of our new Mexican embassy, which just so happens to be right beside the embassy of the United States, it seemed natural to build a wall between them; a Trump wall,” general manager Brett Harston said.

And so, on November 25, the first “Trump” wall will be opened, some years before the US-Mexico wall is likely to be complete.

It will be opened by a President Trump impersonator who has greatly impressed Mr Inder.

“He’s so good, he’s awful,” Mr Inder said.

“You’d think it was him.”

Mr Inder said he was expecting a record crowd for the event.

Tasmazia includes eight mazes, one of which is said to have been the world’s biggest when it was planted.

Other attractions include the model Village of Lower Crackpot and a lavender farm.

In a video promoting the wall opening, the impersonator describes Tasmazia as  “a-maze-ing”.

“This ain’t fake news ...,” he says.

It is not clear whether President Trump has ever visited Tasmania.

It was suggested last year that a Westbury cricket ground be named after him.

Mr Inder is bullish about Kentish and the surrounding region’s potential for a tourist boom, which would presumably help make Tasmania great again.

“We’ve got a huge future here,” he said.

“It’s going to be one of the best little destinations in the country.”

He said he had always regarded the Devonport-Ulverstone-Latrobe-Kentish-Deloraine district as one big area.

“They are coming round to it now,  starting to advertise each other and to acknowledge it as one place,” he said.

“It’s madness to think of it any other way.”
