Despite being granted permission to build a new 2200 seat cinema, Westfield Kotara wants to make adjustments to the plans before beginning construction.
The new application would include a restaurant precinct that would be located adjacent to the cinema.
Kotara and Adamstown Heights residents claim this alteration would result in the loss of 250 parking spaces.
They claim this loss would further increase the problem of nearby streets being clogged with cars because shoppers are unable to find a park within the complex.
The application proposes to build 20 new parking spaces for staff, but some councillors say this will not fix the problem as many more will be employed to run these new facilities.
