Constraint readout
81.49 km² - this suburb is highly constrained by planning overlays.
Elevation hillshade with street names, clipped to Shannon's boundary, with the flood, bushfire and environmental overlays drawn on top. Magenta is where aircraft were observed in the sampled period, brightest below 3,000 ft.

Aircraft noise and flight paths over Shannon
Two different things, kept apart on purpose. The ANEF contour is the planning instrument - a forecast published per airport that planning schemes use to control noise-sensitive development. Observed overflight is what a sampled aircraft-tracking feed actually recorded over the suburb - where aircraft flew, how low and how often.
Observed overflight - sampled 4 Sep to 3 Oct 2026
Night movements: not established - night is sampled as often as day, but too few night flights have been seen here to conclude either way.
Traffic is sampled rather than watched continuously, so every figure is a floor: aircraft not captured between samples are not represented. Rates are per 500 m square - the busiest square in the suburb, not a count of flights over the suburb - and a square is only rated where enough traffic was seen to measure it. Altitudes are above mean sea level. Flight paths change with runway use, weather, season and airspace design. This is a record of observed traffic; it is not a noise contour and not a planning control.

Across its 81.49 km², Shannon is highly constrained by planning overlays. About 6% of the suburb sits within a mapped flood overlay, and 100% is flagged bushfire-prone. There is 1 heritage-listed site on record, and the dominant land-use zone is Rural. The median lot measures about 135,023 m² across 60 parcels.

See exactly which overlays touch a single property - the interactive map is free. Need it on paper? A full planning PDF is just $9.
The report's Aircraft Overflight page narrows that to the address itself: how many aircraft a day, how low, and at what heights.
Published flood models are held here: a Flood Model Report is available for about 30 Shannon addresses (+$9 with the planning report).

Is Shannon flood-prone?
About 6% of Shannon falls within a mapped flood overlay, against the council-wide suburb average of 9%. Modelled flood depth, velocity and flood level are held for about 30 Shannon addresses, from published flood studies; the free check on the Flood Model Report page says whether a model reaches a given address.
Is Shannon bushfire-prone?
Around 100% of Shannon is mapped as bushfire-prone, compared with a Central Highlands average of 96%.
Is Shannon under a flight path?
Aircraft were observed over about 1% of Shannon in the period sampled, but only above 3,000 ft - the lowest measured was 6,000 ft. Traffic is sampled rather than watched continuously and flight paths change with runway use, weather and season; the ANEF contour is the planning instrument.
What is the zoning in Shannon?
The dominant planning zone in Shannon is Rural, though the suburb also includes Environmental Management and Low Density Residential.
Does Shannon have heritage-listed places?
Shannon has 1 heritage-listed place on record.
What is the typical lot size in Shannon?
Across 60 surveyed parcels in Shannon, the median lot size is about 135,023 m².
