Move back, then secure people
Move everyone away from split-level gardens. Bring pets and children behind a shut door by a route that stays well clear of the animal.
AVAILABLE 24/7 · GLENHAVEN
Glenhaven’s large established blocks, mature canopy, sandstone landscaping and creek-connected reserves create many possible travel lines. Keep the scene still and describe the exact level of the property where the snake was last seen.
Before anyone searches in Glenhaven, stop foot traffic and keep the route around old mans creek influence quiet. The snake should not be chased, handled, boxed in or harmed.
Move everyone away from split-level gardens. Bring pets and children behind a shut door by a route that stays well clear of the animal.
Choose a protected view suited to Glenhaven: glass, a vehicle, an upper landing or another solid barrier. If no such view exists, retreat and keep the final location in mind.
Anchor the report to old mans creek influence: name the exact wall, gate, bay, paddock, path or object and the direction the snake took. Do not step closer for a photo.
Call Snakes in the City with the Glenhaven address or entrance pin, the last-seen time, tiled-roof homes access and any people, animals, machinery or locked areas involved.
Keep the patient completely still at the Glenhaven scene and call Triple Zero. Apply a broad pressure immobilisation bandage over the bite and along the whole limb if available, splint it, and follow the operator. Do not wash, cut or suck the bite, use a tourniquet or pursue the snake. NSW Health requires emergency assessment for every suspected bite.
The useful local distinction is between damp creek-fed spaces and dry, prey-rich structures. Red-bellied black snakes may be associated with water and frogs; eastern browns with open ground and rodents; diamond pythons with mature trees and roof cavities; small golden-crowned snakes with sheltered sandstone and leaf litter. None of those associations replaces an on-site identification.
Stone walls, stairs, deck undercrofts and planted terraces create repeated changes of level. Watch from above or through glass and never descend toward a hidden snake.
Damp gullies, drains, shaded pools and frog activity can support wildlife movement. Keep the last observer on the dry, developed side of the scene.
Sheds, coops, feed, long grass and machinery broaden the search area. Close stock into a separate paddock only when that can be done without entering the sighting zone.
Glenhaven is shaped by its reserve spine and the upper reaches of local creek systems, while many streets contain 1970s and 1980s brick homes, deep gardens, pools, terraces and tiled roofs. The suburb grades from suburban lots toward larger fringe properties, so one search method does not fit every address.
On the Castle Hill side of Glenhaven, the nearby Fred Caterson Reserve corridor contains Cattai Creek and connected bushland. When calling, say whether the sighting was on the Glenhaven Road or creek-facing side, near a reserve boundary, or on a higher split-level garden. Do not enter reserve vegetation to search.
On a sloping block, ‘backyard’ is not precise enough. Tell the catcher whether the snake crossed the upper driveway, pool terrace, lower lawn, retaining wall, roofline or creek-facing fence. If access is from a different street or a long battle-axe drive, include that at the first call.

Glenhaven contains the conditions described below, but that does not make every listed species common at every address. Age, shadow, camera exposure and viewing angle alter markings. Keep the same safety margin until the individual animal is assessed.
Well suited to wooded northern Sydney and may travel through trees, pergolas, gutters or roof spaces. It can remain hidden while following rats or possums.
A possible visitor to creek lines, wet gardens, ponds and pool surrounds. Give it room and avoid blocking its path toward cover.
May occur near drier paddock margins, coops, sheds or stored feed where rodents are present. Colour is too variable for safe DIY identification.
A small night-active species associated with leaf litter, sandstone and damp shelter. Do not pick it up because it looks small.
May climb vegetation, fences or structures. It is variable in colour and can be confused at a glance with other slender snakes.
Around Glenhaven tiled-roof homes, maintenance can expose travel lines and reduce prey or shelter near people. It cannot seal a property from native wildlife. Treat “snake-proof” guarantees and plug-in, solar, vibration or chemical repellent claims with caution.
If movement or a snake is seen near eaves, keep manholes closed and avoid entering the roof. Record the side of the building and whether birds, rodents or possums have also been heard.
Close the gate from outside the affected enclosure if safe, turn off automatic activity remotely and do not lift skimmer lids, pump covers or loose pavers.
Supply gate codes, driveway landmarks, stock locations and the last-seen paddock or building. A pin and a person at the entrance can prevent delay.
If the animal slips into a retaining wall, roofline or dense garden, freeze the layout. Photograph the area from safety—not the snake—so the catcher can see the openings and fixed landmarks. Avoid banging on walls, flooding gaps or lighting a fire. Those actions can drive the animal deeper or toward people. Search confidence depends on access, construction and how long ago the sighting occurred.
The photographs below come from Snakes in the City field work in northern Sydney. They show Harley and examples of diamond python and other habitat-linked reptiles, not animals recorded at this particular Glenhaven property. Use them for context, never as a reason to move closer.

Use this Glenhaven map to confirm the correct suburb, then send the actual driveway, gate, building or campus entrance. On tiled-roof homes, a dropped pin can prevent delay; place it from safety rather than walking back into the affected zone.
No. Rats, possums, birds and building movement can make similar sounds. A confirmed sighting or professional inspection is more reliable than sound alone.
No. Creek and bushland proximity can increase opportunity, but sightings also depend on shelter, prey, weather and chance.
Visible joints and accessible edges can be assessed, but a deep structural void may not be completely searchable. Do not dismantle the wall yourself.
Secure animals away from the sighting if that can be done from a safe route, stop people entering the shed or coop and identify feed and rodent activity for the catcher.
It may move on immediately or take cover. Keep the enclosure quiet and maintain a distant view rather than trying to direct it.
Sometimes a clear safe image helps, but colour varies with age, light and angle. Treat every unidentified snake cautiously.
