She will be replacing Rellie Kaputin, who sustained an injury recently.
Monagi, who has a personal best of 13.82 seconds in the 100m hurdles, won the silver medal in this event at the recent Pacific Games in Apia, clocking 13.99 secs behind Australian Brianna Beahan.
During its meeting in Port Moresby over the recent long weekend, the Athletics PNG Executive commended Monagi for her initiative in submitting a written proposal, seeking support for her program next year and setting out her goals.
“It was good to see that Adrine had resumed training on 5 August after a break of only two weeks and this was a big plus in her favour as we considered our options,” said APNG Secretary Philip Rehder.
Despite being only 24 years of age, Monagi has a lot of big competition experience, having attended the Commonwealth Youth Games, IAAF World Junior Championships, two Commonwealth Games, several Pacific Games and Oceania Championships and a number of NCAA Division two national championships in the USA.
The World Championships will be staged from September 27 to October 6.
