A group of Keiraville residents are growing tired of the suburb becoming "the parking lot for the University of Wollongong".
Nearby residents have expressed concerns regarding a development application for 58-60 Murphys Avenue.
The DA includes the demolition of existing structures and tree removals, and the construction of multi-dwelling housing - ten townhouses, associated landscaping and infrastructure.
Nearby resident Yvonne Toepfer said the proposal was a "massive over-development".
"It's an inner-city development in a suburban, low residential area," she said.
"It's stretching the limits of all the boundaries... Everything is to the maximum. It's quite over-the-top.
"It's a battle-axe block. Where two houses were, there's going to be ten."
Ms Toepfer, who has lived in Keiraville for 26 years, said the proposal would have a raft of negative impacts, including affecting parking, traffic, noise and privacy.
She said parking and traffic issues could be exacerbated if the units were rented to university students, and each unit could have multiple vehicles attached to it.
"To put it mildly, Keiraville is becoming the parking lot for the University of Wollongong, or is already," she said.
"They're changing the suburb dramatically... (This DA) is just too big for the area.
"This land being slightly elevated to the surrounding ones (means) the double-storey is inappropriate because all the ones around it are single-storey homes."
A Wollongong City Council spokesperson said council is still assessing the DA and the submissions received.
Another neighbour, Eric Kivi, said he hoped priority would be given to protecting the amenity of residents and considering the environmental implications.
"The DA will overlook backyards of five properties and cause more congestion in Keiraville," he said.
"Furthermore, the developer is proposing to remove 25 trees in an area severely affected by flooding in the past."
A meeting of residents to protest the proposal will take place at 11am on Tuesday at 64 Murphys Avenue.
