The Queensland Government believes Mutchilba disappeared in 1999; however, locals are convinced it happened more recently. One thing is certain: they want their town back.
"We're not a suburb of Dimbulah," said Muccignat. "A lot of people have lived here for a long time, and everyone was under the impression we were living in Mutchilba."
The state Government is doing all it can to fix the situation, but first Mutchilba has to jump through a series of bureaucratic hoops, including consulting the community on town boundaries. In the meantime, the state Premier, Campbell Newman, has written a letter of support, as has Bob Katter, the federal MP, who visited the town.
Mutchilba consists of one shop, a community hall, a post office, a school (with 27 pupils) and a dozen houses. But it has been a town since 1901, when a railway station was built there. It used to stage an annual Mango Mardi Gras, and is considering reviving the festival.
"There's a strong sense of community pride," said Muccignat.
The confusion has created some potentially serious situations. When local Harry Adams suffered a heart attack recently, he telephoned for an ambulance. He found himself arguing with the emergency operator - who wanted to send a team to Dimbulah - about where he lived.
Muccignat wants the mistake remedied as soon as possible. "We're hoping we'll get our name back by Christmas."
