Two men have fooled North Korea into believing they were top golfers to enter an international tournament in the secretive state.

Morgan Ruig and Evan Shay, both 28 and from Brisbane, cut short their polo trip in Beijing when they entered the annual championships by email.

They pranked authorities into believing they were the Australian Golf team, and went on to play so poorly a caddy told them they brought shame to their families, Mr Shay said.

The pair simply applied by email and expected the joke to end there.

'We just emailed them really. I don't think they're massive on the internet over there so I don't think they had many opportunities to research,' Mr Shay, director of Nodad Design And Construct, told Daily Mail Australia.

'We didn't think we'd actually be accepted.'

But to Mr Shay and Mr Ruig's surprise they were accepted and they 'just went for it'.

The pair had claimed to be low handicaps and even had green blazers with the Australian logo on the breast made to look the part.

'Everyone thought we were actually pretty legit,' Mr Shay said, until they 'put the ball in the river'.

'We didn't do well,' Mr Shay said, laughing.

'Our caddy said we brought great shame upon our families.'

Mr Shay said the pair barely even play golf leisurely.

The people in North Korea 'were all pretty respectful over there', Mr Shay said.

Understandably though, they had their concerns.

'We were very nervous handing our passports over at the border. There are stories of people not coming home,' Mr Ruig told The Courier-Mail.

There were 85 international competitors at the North Korean Amateur Golf Championships.

Most were just off scratch with low handicaps, Mr Shay said.

The two-day tournament in early October was based at Pyongyang Golf complex, North Korea's only golf course, about 27km from capital city Pyongyang.

Kim Jong-Il is claimed to have opened the course in 1987 and shot 11 hole-in-ones on his first ever attempt at golf, with a world record 38 under par.

The Brisbane men were chaperoned around for the entire five-day trip as part of the conditions of their travel.

They were taken on official visits around the city, and pictures show them standing at the Mansudae Grand Monument statues of Kim Jong-Un and Kim Jong-Il with bouquets of flowers.

Mr Shay said they were chaperoned around for the entire five-day trip as part of their conditions.

The pair have been friends since they met at Brisbane Boys College. Mr Ruig is associate director at property group Cushman & Wakefield.
