St George, the Shire & strata

Southern Sydney Electrician

More people live in less space here than anywhere else we work, and most of them live above or below somebody. That single fact changes who owns the fault, who pays for it, and who has to agree before anyone can start.

The shape of the place

Three different places, stacked on top of each other

Southern Sydney gets treated as one region and it is really three, with almost nothing electrical in common between them.

There is the St George corridor, running from Rockdale and Arncliffe through Kogarah to Hurstville, and it is the densest place we work by a wide margin. Georges River Council holds about 152,000 people in 38 square kilometres, which is close to 4,000 people per square kilometre. Bayside is similar. For comparison, the Northern Beaches runs at roughly 1,000 and The Hills Shire at under 500. Density like that is not a statistic, it is a housing type: apartments, from three-storey red brick walk-ups of the 1960s and 70s through to the towers that have gone up around Hurstville and Kogarah stations.

Then there is the suburban middle of the Shire, through Miranda, Caringbah, Gymea, Sylvania, Jannali and Engadine. Houses, largely postwar and later, on ordinary blocks, with the ordinary problems of installations that have been added to for sixty years.

And then there are the edges, which are wilder than people expect. Nearly half of Sutherland Shire is national park, 173 square kilometres of its 370, and the ocean front from Cronulla to Kurnell has the same salt problem as any surf coast.

So the useful question here is not what suburb you are in. It is whether you own the thing that is broken, because in this part of Sydney there is a very good chance you only own part of it.

Strata

The most expensive question in an apartment is who owns the fault

Not what is wrong with it. Whose it is. Here is where the line actually falls in a New South Wales strata scheme.

From the street to your power point who has to pay to fix it, stage by stage Owners corporation Lot owner depends, and this is what gets argued about Point of supply: the distributor Point of supply the distributor Main switchboard: common property Main switchboard common property Meter room: common property Meter room common property Rising mains: more than one lot Rising mains more than one lot Your submain and board: depends where it sits Your submain and board depends where it sits Inside your lot: points and fittings Inside your lot points and fittings where the arguments happen FOUR THAT SURPRISE PEOPLE Recessed ceiling downlight usually the owners corporation Hanging light fitting usually the lot owner Meter in the meter room owners corporation Switchboard inside your unit lot owner

What it means: the broad rule is that anything serving more than one lot is common property, so the main switchboard, the meter room and the rising mains belong to the owners corporation. Anything serving only your lot and sitting inside it is yours. The stage that gets argued about is your own submain and board when they sit outside your front door, and light fittings, where a recessed downlight is usually common property and a hanging one usually is not. We find the fault and put in writing which side of the line it landed on, which is what actually settles it.

The reason this matters more than it sounds is section 106 of the Strata Schemes Management Act. It requires the owners corporation to properly maintain and keep in a state of good repair the common property, and to renew or replace fixtures and fittings in it. That duty is positive rather than reactive, and it is not excused by an empty capital works fund. Where an owner suffers loss because it was not done, the path runs to NCAT.

The practical consequence for a committee is that a known electrical defect on common property is not something you can leave on the agenda for two years while people argue. And the practical consequence for an owner is that a fault you have been quietly living with may not be yours to fix at all.

Local conditions

Six things about Southern Sydney that change the job

Most of these only come up where people live stacked on top of one another, which is most of this part of Sydney.

The rising mains are the real asset

In any older block, the cable running up the building to feed every unit's meter is the thing that matters most and gets looked at least. In a 1970s walk-up it is often around fifty years old and was sized for a household with a fraction of today's appliances.

It rarely fails suddenly. It warms, then a termination gets hot, and the early signs are flickering, one unit dimming when a neighbour's appliance starts, or a smell in the stairwell. It is common property, it affects every lot, and it is the single most worthwhile thing for an older committee to have inspected.

Half the job is knowing whose it is

In a house, a fault is a fault. In a strata scheme it is also a question of jurisdiction, and getting it wrong costs people money and goodwill. An owner pays for something the building should have covered, or a committee spends the fund on something that was never theirs.

We work the boundary out before quoting rather than after, and we put it in writing. A clear one-page finding that says where the fault is and which side of the line it sits on is usually what ends the argument, whichever way it goes.

Car chargers need a vote, not just a sparky

A charger in an apartment car space sits on common property, so it usually needs a by-law under section 108 of the Strata Schemes Management Act. That is a special resolution, passed if no more than 25 per cent of votes cast are against it, with an easier threshold where the works count as sustainability infrastructure.

In an existing car park the charger itself may be exempt development under the planning rules, though councils vary. The electrical side is usually the easy part: a supply metered to you, so your charging lands on your bill rather than the building's.

Plan the building, not the car space

The mistake buildings make is approving chargers one at a time. The first four are easy, the fifth gets told the supply cannot take it, and now there is a fairness problem on top of an electrical one.

Working out the building's capacity once, and using load management so the available supply is shared rather than exceeded, is dramatically cheaper than a supply upgrade later. It is a conversation worth having at a committee meeting before it becomes a queue of individual applications.

The ocean front is a different environment

Cronulla, Wanda and the Kurnell side face open surf, and airborne salt from breaking waves is what drives corrosion. Within a few hundred metres of the sand you want marine grade fixings, enclosures chosen for the position, and dissimilar metals kept apart.

Port Hacking and the Georges River frontages are considerably milder, because sheltered water throws far less salt into the air than surf does. The full detail is on our Northern Beaches page, and it applies here just the same.

Nearly half the Shire is national park

173 of Sutherland Shire's 370 square kilometres are national park, which is why the developed part is so concentrated and why the southern end feels remote so quickly. Royal National Park was proclaimed in 1879, the first declared in Australia.

Bundeena and Maianbar sit inside it on the southern shore of Port Hacking, reached by road through the park or the ferry from Cronulla. Those are jobs to scope properly and do in one visit, not three.

By area

What the buildings are, and what usually goes wrong

Broad strokes, with exceptions in every street, but this is the pattern.

Engadine, Heathcote, Menai, Bundeena, MaianbarHouses on the bush and park fringe, some remoteOwnersBushfire zone work, supply reliability, and everything done in one visit

Two things worth pulling out of that. The walk-up belt through Rockdale, Carlton and Allawah is the largest concentration of ageing common property electrical infrastructure we deal with anywhere, and it is mostly owned by committees who have never been told what the rising mains are.

And the waterfront strip along the Georges River is a genuinely different animal from the ocean front a few kilometres away. Same postcode range, much milder salt exposure, and a completely different specification for anything mounted outside.

For committees

What we give a strata committee that a quote does not

Most electrical quotes to an owners corporation are a price for a job somebody has already decided on. That is fine when the job is obvious and unhelpful when it is not, which in an older building it usually is not.

What a committee actually needs is a finding it can put in front of owners: what is wrong, whether it is common property, what happens if it is left, and what the options cost in order of urgency. That is what makes a motion pass at a general meeting, and it is what protects the committee if somebody later asks why nothing was done.

It also matters because of section 106. The duty to maintain common property is a positive one, so once a defect is known, doing nothing is a decision with consequences rather than a neutral act. A written finding starts the clock honestly and gives the committee something to act on rather than a vague worry.

The other half is practical. Buildings are full of people who work, sleep at different hours and want notice before their power goes off. We would rather agree the outage window, notify properly and do the work once than turn up and improvise in a stairwell.

How it got here

A short history that still shows up in your switchboard

The railway made St George commutable, the park kept half the Shire empty, and the 1970s filled the gap with red brick.

  1. 1879

    Royal National Park is proclaimed

    Formally proclaimed on 26 April 1879 and the first national park declared in Australia, covering about 151 square kilometres. It is the reason nearly half of Sutherland Shire is still bush, and the reason the developed part of the Shire is as concentrated as it is.

  2. 1884

    The railway reaches Hurstville

    The Illawarra line, built primarily to serve the Coal Cliff Colliery, opens to Hurstville in 1884, Sutherland in 1885 and Waterfall in 1886. St George becomes commutable and starts subdividing, which is why the oldest housing clusters along the line rather than the water.

  3. 1939

    The Cronulla branch opens

    On 16 December 1939 the branch line reaches Cronulla, and the beach stops being a day trip and starts being a suburb. Much of the older housing on that side of the Shire dates from the decades either side of it.

  4. 1960s

    Red brick, three storeys, no lift

    The walk-up flat arrives in quantity through Rockdale, Kogarah, Carlton, Allawah and Hurstville. Solid buildings, sensibly built for their day, and wired for a household with a fridge, a television and not much else. Most of that rising main and meter room switchgear is still in service.

  5. 2016

    The councils merge

    Hurstville and Kogarah become Georges River Council on 12 May 2016. Rockdale and Botany Bay become Bayside Council on 9 September. Two amalgamations covering the densest part of southern Sydney, and a single set of planning controls across it.

  6. Now

    Towers above, walk-ups below

    Around 152,000 people live in Georges River's 38 square kilometres, close to 4,000 per square kilometre, in a mix of new towers around the stations and fifty-year-old blocks in the streets behind them. Two completely different sets of electrical problems, often on the same street.

Compliance

Licensed, accredited and certified

Licence 387609C Level 2 accredited & insured

Work is done to AS/NZS 3000 and certified. We lodge a Certificate of Compliance for Electrical Work within 7 days of testing, which since 1 July 2026 goes through the BCNSW eCert portal.

In strata that certificate matters more than usual, because it is the document that shows the owners corporation the work on its common property was done properly and by whom. We provide it alongside a plain finding of what was wrong and what was done, so it can go straight into the building's records rather than into somebody's inbox.

Anything at the point of supply is Level 2 work, which covers service line repairs, supply upgrades and metering changes. We hold the accreditation, so a building that needs more supply is not waiting on a second contractor to become available.

None of the strata information on this page is legal advice. It is the general position under the Strata Schemes Management Act, and anything specific to your scheme should be confirmed with your strata manager or a strata lawyer.

Good to know

Southern Sydney electrical questions

Who pays when something electrical fails in an apartment?

It depends on where the fault is, not on who noticed it. The broad rule in NSW is that anything serving more than one lot is common property and the owners corporation's responsibility, and anything serving only your lot and sitting inside it is yours. So the main switchboard, the meter room and the rising mains are the building's problem, and the circuits, points and fittings inside your unit are yours. The genuinely arguable part is your own submain and board where they sit outside the lot. Our job is usually to find the fault and tell you clearly which side of the line it landed on, in writing, so nobody has to guess.

Our building is a 1970s walk-up. What should we be worried about?

The rising mains, which is the cable running up through the building feeding every unit's meter. In a block of that age it is often around fifty years old, was sized for a household with far fewer appliances, and has spent all of that time in a riser nobody opens. It rarely fails suddenly. It gets warm, then it gets hot at a termination, and the symptoms show up as flickering, as one unit's lights dimming when a neighbour's appliance starts, or as a smell in the stairwell. This is the single most worthwhile thing for an older strata committee to have looked at, because it is common property and it affects every lot in the building.

Can I put an EV charger in my apartment car space?

Usually yes, but it needs the building's agreement, not just an electrician. Because the charger and its cabling sit on common property, you generally need a by-law under section 108 of the Strata Schemes Management Act, which is a special resolution passed if no more than 25 per cent of the votes cast are against it. Where the works are treated as sustainability infrastructure the threshold is easier. In an existing car park a charger may also be exempt development under the planning rules, though councils vary. The practical work is usually a metered supply so your charging is billed to you rather than to the building.

Can the building's supply handle everyone charging a car?

Not if everyone installs a full-speed charger on its own circuit and no thought is given to it, which is exactly how most buildings get into trouble. The sensible approach is to plan the building once rather than approve chargers one at a time, and to use load management so the available capacity is shared rather than exceeded. Doing that early is far cheaper than a supply upgrade later, and it stops the fifth owner being told no after the first four were told yes. This is worth raising at a committee meeting before it becomes a queue of individual applications.

Does the owners corporation have to fix common property?

Yes, and the duty is stricter than most committees realise. Section 106 of the Strata Schemes Management Act requires the owners corporation to properly maintain and keep in a state of good repair the common property, and to renew or replace fixtures and fittings in it. It is a positive obligation rather than a reactive one, and it is not avoided by saying there is no money in the fund. If an owner suffers loss because it was not done, they can take it to NCAT. In practice that means a known electrical defect on common property is not something a committee can safely leave on the agenda for two years.

Do you work at Bundeena, Maianbar and the national park edge?

Yes, and we plan those jobs differently. Nearly half of Sutherland Shire is national park, and Bundeena and Maianbar sit inside it on the southern shore of Port Hacking, reached either by road through the park or by the ferry from Cronulla. It is a long way from anywhere in either direction. What that means practically is that we would rather scope the work properly, bring everything in one go and do the lot, than make three trips. If you have been putting other things off, that is the visit to mention them.

Is Cronulla as bad for corrosion as the Northern Beaches?

On the ocean front, yes. Salt in the air comes from breaking surf, and Cronulla, Wanda and Greenhays face open water the same way Collaroy does. Within a few hundred metres of the sand you want marine grade fixings, enclosures chosen for the position and dissimilar metals kept apart, or the fittings fail early and the brackets fail before the fittings. Port Hacking and Georges River frontages are milder, because sheltered water throws far less salt into the air than surf does. We have written the detail up on our Northern Beaches page and the same principles apply here.

How does your pricing work?

Attending your job is a chargeable callout. We confirm what it costs when you book, and the price for the work itself is agreed before we start, so there are no surprises on the invoice.
