Residents of Ivory Lane, Ormiston, have vowed to take their plight to the state government after a second koala was injured near a 24-lot housing development.
Ivory Lane resident Kim Rossi was horrified to find a juvenile male koala hanging upside down by its back leg after getting tangled in her back fence.
She rang Indigiscapes Wildlife Rescue and a volunteer rang her back before calling the Daisy Hill Koala Ambulance on Sunday.
The koala, nicknamed Ivor after the Ormiston lane where he lived, was taken to Manly Veterinary Clinic for painkillers before being driven to Australia Zoo.
The 8kg koala had his leg amputated in a two-hour operation at Australia Zoo on Monday.
The incident happened four months after a four-year-old female koala, also living in trees at Ivory Lane, was put down at the Moggill Koala Hospital on January 31 after succumbing to stress-related diseases.
Days later, on February 2, developer Fiteni felled 27 koala trees on its nearby Wellington Street property.
Mrs Rossi took to Facebook site "Save Our Koalas by Saving Our Trees", to air her grievances.
"I can only determine that he was trying to make his way to what was once an abundant food source and refuge for him," she wrote.
"We have lived here for many years and have never had this happen.
"This would be because in the past there were trees the koalas could traverse between from our property to the many which were once standing in Fetini's site.
"With these destroyed, the koalas have no choice but to try and scale a metal and barbed fence.
"In the case of Ivor, his leg managed to become severely lodged to the point it was shattered and he became stuck in the downside position."
Mrs Rossi said Ivor would never be released into the wild again and it would be vital for him to stave off infection in the next week to survive.
Other Ivory Lane resident Adelia Berridge and neighbour Judy Rose, formed a lobby group in February to push for adequate protection of the local wildlife, koala trees and residents' living standards.
Mrs Berridge said developer Fiteni refused to communicate with the residents but had sent instructions telling them to address their concerns to the building contractor.
"Fiteni won't communicate with us at all and are in denial that there is a problem here with the wildlife," she said.
"They refuse to to talk about solving the problems with the wildlife, the chopping of the koala trees or the purposing of the land."
Mrs Berridge said she believed cracks in her house were caused when large machinery was used to compact piles of dirt and fill used to build up the Fiteni site.
Koala Action Group Debbie Pointing said the future for the Ivory Lane koala would be grim if council granted a further development application for nearby Wellington Street.
Ms Pointing said the property was zoned Environmental Protection and allowing it to be subdivided would result in the loss of more koala habitat.
"Allowing this block to be subdivided sets a precedent for other larger blocks to also be subdivided.
Landowner Steve Lambourne applied to council last year to clear trees which were protected under a Vegetation Protection Order by the former land owner Division 1 councillor Wendy Boglary.
"We are not touching a tree on the property or any gum tree because the trees that are being removed are just weeds and not even native," Mr Lambourne.
"We're keeping every gum tree on the site - not one is being removed and will also plant extra trees.
"This is the place where we have wanted to live all our lives, why would we destroy the land that we want to enjoy?
"Fifteen years ago there were no houses here and these people have moved into their own sanctuary but don't want anyone else to - it's unfair.
"There is a whole heap of bushland in Redlands that is under-utilised."
Redland City Council has been contacted for comment.
