Excavation in Bonnet Bay
What's different about digging in Bonnet Bay
Bonnet Bay, in short
Bonnet Bay sits about 27 kilometres south of the city. It's anchored by Bonnet Bay, Woronora River and Prince Edward Park. It's ringed by Como, Woronora, Kareela and Jannali. What's changing: knock-down rebuilds, pools and basements cut into rock, and retaining on the bush-backed slopes.
The houses, and what they need
Most blocks in Bonnet Bay, around Bonnet Bay, are mid-century and newer brick homes on bush-backed blocks, with knock-down rebuilds. Near Bonnet Bay, the older brick and fibro is renovate-or-rebuild ground. Most Bonnet Bay jobs are rock excavation, pool digs and retaining walls.
The ground under Bonnet Bay
Bonnet Bay sits on Hawkesbury sandstone with rock close to the surface on bushland ridges, out toward Bonnet Bay. Around Woronora River a Bonnet Bay dig hits sandstone in the first metre, sawn at the edges so the neighbour's ground stays put and broken in the middle. Around Woronora, rock like this is sawn clean at the edges and broken in the middle.
The council, access, and getting to you
Bonnet Bay is Sutherland Shire Council ground; near Bonnet Bay, bushfire and tree protection controls apply and we dig to the approved plans. The Bonnet Bay crew comes in off Menai Road or Heathcote Road, where the fall has to be benched and retained.
How it runs

Every job follows the same sequence, whether it's a single trench or a full site cut.

Excavation in Bonnet Bay, answered
How much does excavation cost in Bonnet Bay?
It depends on the volume of material, the ground (hawkesbury sandstone with rock close to the surface on bushland ridges), access for the machine and how far spoil has to be carted. Every job gets a written quote after a site look, with the dig, cartage and cleanup spelled out, so you know what’s included before anything starts.
Do I need council approval before you dig in Bonnet Bay?
Usually, if the excavation is part of a build. Cut and fill beyond set limits, work near boundaries and anything on a lot with a flood, bushfire or heritage overlay needs approval as part of the DA or CDC. We work to the approved plans; check with your certifier before the dig is booked.
How long does an excavation job take in Bonnet Bay?
A trench, pool dig or single pad is a day or two; a knock-down site cut or a basement runs longer and depends on volume, ground and weather. Dates come with the quote, not after.
Is there rock in Bonnet Bay?
Yes. Hawkesbury sandstone with rock close to the surface on bushland ridges. Across the Shire and on the St George ridges, sandstone is usually within the first metre, so pools, basements and garage cuts are rock jobs: sawn at the boundaries, broken in the middle, carted as rock. It’s in the quote from the site look.
Can you dig a pool into the rock on my Bonnet Bay block?
Yes, and it’s the standard Shire pool. The shell outline is sawn into the sandstone, the middle is broken out, the rock is carted, and the edges are left clean for the concrete or the fibreglass shell. Slower than a clay dig and priced for it.
Do you do duplex site cuts in Bonnet Bay?
Yes. Through St George it’s the most common job: the old house down, slab and footings out, the block stripped, and two pads cut to the engineer’s spec, in clay on the ridge top and into sandstone where the design goes deep.
My Bonnet Bay block backs onto a bush gully with a bushfire rating. What does that mean for the dig?
Three things: the back of the block is sandstone and steep, the bush carries an asset protection zone that sets clearing distances, and the trees are protected. The cut is benched, retaining is planned in, and the clearing is done to the approved plan.
There’s no way to get a machine onto my Bonnet Bay waterfront block. Can you still dig?
Yes. Mini machines are craned in over the house or walked through it, rock is broken out and craned or barrowed away, and on the Port Hacking and Georges River blocks a barge is sometimes the answer. Slower than a side-gate job and priced for it.
