Brisbane Residents Sound the Alarm: 'We Didn't Move Here to Watch the Creek Turn Green'

Carolyn Tran moved her family from Blacktown to Rocklea three years ago chasing cheaper housing and what she described as a quieter life near the water. Last month she photographed a bloom of blue-green algae stretching across a 400-metre stretch of Oxley Creek — the third such event since February. "We didn't move here to watch the creek turn green," she told neighbours at a community meeting held at the Rocklea Community Hall on June 28. Her photos have since circulated through several Southeast Queensland environment groups, landing in the inboxes of councillors and state MPs.

The timing matters. Sydney just recorded its hottest June since 1859, and climate scientists are being unusually blunt about what that signals for the rest of the eastern seaboard. Brisbane's own Bureau of Meteorology records show average July maximums in the CBD have crept up 1.4 degrees since 2000. The city is also absorbing roughly 1,700 new residents per week as the migration wave from New South Wales and Victoria accelerates, driven by housing costs. Every one of those arrivals needs roads, water, stormwater infrastructure — and that pressure is landing on catchments that were already stressed.

At the same time, the LNP state government is pushing hard on 2032 Olympics construction timelines. The Gabba rebuild alone will redirect significant stormwater flows in Woolloongabba, and residents in adjacent Norman Park and Coorparoo have raised concerns with Brisbane City Council about cumulative runoff impacts still being studied under the South East Queensland Catchment Management Program. The Healthy Land and Water organisation, which monitors waterway conditions across the region, flagged Oxley Creek as a "medium to high risk" catchment in its annual report published in March 2026.

What Residents Are Actually Saying

The Rocklea meeting drew about 60 people, a mix of long-term locals and newcomers from interstate. Several described the same frustration: they receive development notifications in the mail, sometimes with submission windows as short as 15 business days, and feel that by the time community feedback is processed, earthworks have already begun. One man who has rented on Ipswich Road near the Rocklea Markets for eleven years said he has counted seven separate development applications within two kilometres of his property since January 2025.

Down on the Redcliffe Peninsula, the Moreton Bay Waterways Alliance — a coalition of local fishing clubs and conservation volunteers — has logged a 23 per cent decline in seagrass cover in Bramble Bay between 2021 and 2025, based on transect surveys conducted twice yearly. Seagrass is the primary feeding ground for dugong, and the alliance estimates fewer than 40 dugong now regularly use the bay, compared with roughly 70 a decade ago. Members say urban runoff carrying nitrogen and phosphorus from construction sites upstream is the primary culprit, and they want mandatory turbidity monitoring at all Olympic-linked construction zones that drain to tidal waters.

The Logan City Council area is facing its own version of this tension. The Loganholme corridor is earmarked for significant residential expansion under the South East Queensland Regional Plan, and community groups including Logan Environment Watch have repeatedly asked the state government to mandate green infrastructure corridors — bioretention basins, riparian buffers — as conditions of approval rather than voluntary offsets developers can buy their way out of. The group submitted a 47-page report to the Department of Environment and Science in April; as of this week they say they have received an automated acknowledgement and nothing further.

Where This Goes From Here

Brisbane City Council's Environment, Parks and Sustainability Committee is scheduled to meet on July 22, with the Oxley Creek Transformation Master Plan on the agenda. Environment groups are urging residents to lodge written submissions before July 18, the public comment deadline. The Queensland Environment Department is also currently reviewing its Wetland Protection Policy, with draft amendments expected by September 2026 — a process that will directly affect how development applications near sensitive areas are assessed for the rest of the decade.

For Tran and her neighbours in Rocklea, the immediate ask is simpler: regular, publicly accessible water quality testing results for Oxley Creek, posted online within 48 hours of sampling rather than buried in quarterly departmental reports. "Just tell us what's in the water," she said at the June meeting. "That's not much to ask."
