**Two noises across one fence, only one of them regulated**
Here the instrument is the Environmental Protection Act 1994, which Brisbane City Council names as the law covering nuisance noise city-wide, and Council states that a commercial or industrial property holding a development approval must comply with that approval's conditions. The same Act expressly does not regulate noise from railways or railway signals, and a rail line runs through Geebung. The premises across the fence is regulable; the train behind it is not. Geebung carries no state-controlled road noise corridor either.
**If you operate the premises: your approval conditions are the instrument**
Across the suburb residential-zoned properties outnumber industry-zoned ones by roughly three to one — 1,919 against 614 of 2,583 rateable properties. The fence line does not follow that ratio: 23 homes on the residential side, against an industrial market of 614 holdings, 311 of them unit-type strata tenancies, each with its own plant, deliveries and yard movements. Council states that its default noise standards do not apply where it has approved specific emissions under a development approval or a local law approval; the approval conditions bind instead. So what an operator has to achieve is whatever that approval says, as determined by an acoustic consultant or certifier — a fence is a treatment, not a discharge of an approval condition.
**If you live on the line: what a complaint involves**
Council publishes the sequence it expects — talk to the neighbour, then make a complaint, then keep a nuisance diary for at least 14 to 21 days recording time, date, duration and how the noise affects you. It asks for your name, address and phone number, and says that if a formal notice becomes necessary your address may have to be disclosed. Refrigeration equipment, compressors, generators and air conditioning all sit on the list of devices Council regulates, which is most of what a small industrial tenancy runs.
**What a barrier does at a yard boundary, and what it does not**
The Queensland Department of Transport and Main Roads states the mechanism plainly: noise barriers work by interrupting the path of sound waves. Behind this fence the source tends to be a yard rather than a single machine — hardstand, a loading area, plant standing outside a tenancy — so what has to be interrupted is a spread of paths rather than one, and the answer can change along the run. Which is why the first useful question at this boundary is what the source actually is and where it stands, not how tall the fence should be.
> The industry zone, the abuttal, the strata tenancies, the amenity investigation area and the premises types named on this page describe the kind of site Geebung contains. RYNO has not worked, quoted or been appointed on any of them.
