Several inner-city Brisbane suburbs have been handpicked for a proposed speed limit change, with some limits potentially lowered by 20km/h.

But the proposal has already met with opposition from Brisbane City Council's Liberal National Party administration.

Greens councillor for The Gabba Jonathan Sri said he wanted a blanket limit of 40km/h across his entire ward, including Dutton Park, South Brisbane, West End, Highgate Hill, East Brisbane, Kangaroo Point and Woolloongabba.
