A rezoned, government approved greenfield site on the Yorke Peninsula has stalled because the state utility cannot say whether the network can carry it. The pricing cycles that produced that answer are being reset right now in three states.
A 28 hectare greenfield site at Kadina on South Australia’s Yorke Peninsula has been rezoned for housing, has a developer behind it, and sits in a town the state has formally identified as the commercial and industrial hub of the peninsula. What it does not have is confirmation that water will reach it.
The ABC reported on 6 September that SA Water has been unable to tell the developers of a proposed 340 home subdivision on Abbot Drive whether sufficient capacity exists in its network to service the site. According to correspondence seen by the broadcaster, SA Water advised in May that it was completing a technical analysis to better understand how future demand could be accommodated, and was not yet in a position to confirm either that capacity exists or what augmentation might be required. It had earlier undertaken to set out connection requirements by February, then advised it had underestimated the time needed.
The site’s history makes that hard to file away as a routine engineering delay. In 2024 the land at Daddow Court and Abbott Drive was rezoned from Deferred Urban to a General Neighbourhood Zone through a privately led code amendment signed off by the Minister for Planning, enabling at least 227 low density allotments at a proposed block size of 450 square metres. The state approved the land for housing. Two years later it cannot confirm it can service it.
The government has already said in writing that some developments will not proceed
This is where the story stops being a regional planning dispute.
SA Water’s current revenue determination, made by the Essential Services Commission of South Australia, runs from 1 July 2024 to 30 June 2028. It caps water retail revenue at $3.524 billion and sewerage retail revenue at $1.806 billion, both in December 2022 dollars. Those caps incorporate the recovery of $1.387 billion of capital expenditure that the state government requires SA Water to spend on specific projects during the period, including a Metropolitan Growth program.
Metropolitan. That word does most of the work here.
On its own Housing Roadmap pages, the Department for Housing and Urban Development states that it is not possible to fully address all required investment in water and wastewater infrastructure over the four year period, that some developments may not be able to proceed in the near future, and that the process of infrastructure catch up will take time, with developments phased over coming years.
That is not a leak or an inference drawn from a stalled subdivision. It is published policy. Kadina is that policy meeting a specific paddock.
The same department’s terms of reference for its review of water infrastructure frameworks go further, recording that SA Water has in recent years under invested in the infrastructure necessary to support housing growth, and that land development has been occurring in locations requiring significant new investment in the absence of any truly cost reflective market signal to flag what that infrastructure would cost.
None of which is unusual once you look at how housing programs are counted nationally. The gap between a home that has been unlocked and a home that has been built is where most state housing numbers quietly live. Kadina is the same gap, viewed from the paddock rather than the press release.
What a regulatory determination actually decides
An economic regulator sets the maximum revenue a state water utility can recover from its customers over a fixed period, usually four or five years. That cap effectively determines how much growth infrastructure the utility can build during those years, and where. Land can be zoned, approved and market ready and still be unserviceable, because the trunk capacity that would connect it was not funded inside the determination. The determination is made once. The land waits for the next one.
The four year cycle is the real approval
For builders and developers the practical shift is in who carries capacity risk, and when that risk becomes visible.
A development approval tells you a land use is permitted. It does not tell you the network can carry the load. Approval volumes have been the headline measure of housing supply for years. Serviceable capacity is the constraint sitting underneath them, and it is measured on a completely different clock.
In South Australia the Housing and Urban Development Minister has said the state’s water system is at capacity, that the Yorke Peninsula sits at the edge of the network so connecting more homes there costs more, and that developers should not assume there is endless capacity in the system when they lodge applications. He indicated there are no plans for further funding before 2028, and that any additional money, including for Abbot Drive, would fall to be considered in the 2028 to 2032 cycle. He also noted, as reported by the ABC, that 464 allotments on the Yorke Peninsula have been connected over the past two years.
Read that against the timeline. An application lodged in 2023. A rezoning approved in 2024. An unanswered capacity question in 2026. A funding decision in 2028 that then has to be designed, procured and built.
There is a further wrinkle worth understanding. Augmentation charges in South Australia apply in the Greater Adelaide Region. Since 1 July 2024 new residential greenfield allotments there pay a fixed $10,000 per dwelling, $5,000 toward water and $5,000 toward wastewater, replacing a cost reflective structure the government estimated would have averaged around $100,000 per allotment. Apartments, build to rent, community and not for profit housing are exempt. Outside that region a developer does not pay the charge, and outside that region the metropolitan growth program largely does not reach. SA Water also states that the charge sits on top of any separate requirement to fund augmentation of its infrastructure to service a particular development.
The state does publish a decision making guide setting out pathways where a party is willing to fund works to bring them forward, and directs those enquiries to a major land development contact at SA Water. It is a real option. It is also a transfer of the cost.
Land can be zoned, approved and market ready and still be unserviceable, because the trunk capacity that would connect it was not funded inside the determination.
Victoria and New South Wales are running the same clock
The reason Kadina matters outside South Australia is that every state prices water growth infrastructure through a periodic regulatory process, and three of those processes are in motion at the same time.
In South Australia, ESCOSA has commenced the determination covering 1 July 2028 to 30 June 2032. Its staged program runs a methodology review and a consumer protections review from June 2026 to September 2027, an expenditure assessment from March 2027 to March 2028, and monitoring and reporting from January 2028. Developer contributions and augmentation charges are a named focus area, alongside SA Water’s forecasting of new connections and demand. Connections performance for developers is on the list of service standards under review. Final submissions on methodology are requested by April 2027.
In Victoria, the Essential Services Commission is running the 2028 Water Price Review covering 16 water businesses. Price submissions are due at the end of September 2027, with the determination and final decision in June 2028 setting maximum prices from 1 July 2028.
In New South Wales, IPART is reviewing developer charges for Sydney Water, Hunter Water and Central Coast Council, applied through Development Servicing Plans. Water and wastewater developer charges were last reviewed in 2018. For Sydney Water and Hunter Water those charges were set to zero, meaning the efficient cost of servicing growth areas went into the general cost base and has been recovered from all customers through annual bills ever since. A position paper is due in December 2026, a draft report in April 2027 and a final report in August 2027.
That last point is the sharpest contrast in the national picture. New South Wales spread the cost of growth servicing across every water bill, and separately committed $5.2 billion across four water infrastructure projects to unlock housing capacity in Western Sydney. South Australia charges a capped contribution in the metropolitan region and, outside it, has told industry in writing that some sites will wait.
Three regulators. One window. It closes across 2027 and 2028.
What is actually being decided in the next eighteen months
The South Australian government’s terms of reference ask its review to recommend improvements that would better ensure growth infrastructure is in place when required, irrespective of the timing of regulatory periods. That single phrase is the entire problem, stated plainly by the people who own it.
Whether it gets solved is not visible from outside. Reports under that review are prepared as Cabinet in Confidence and considered by a Cabinet committee. ESCOSA has recorded that the government is considering the findings, and that if recommendations are made it will reflect them in its approach to the 2028 determination. Industry will see the outcome in the determination, not before it.
There is a federal layer as well. The $2 billion Local Infrastructure Fund announced in the 2026-27 Budget will fund local governments and state owned utilities to deliver water, wastewater, stormwater, road and electricity connections that enable new housing, with a portion reserved for regional areas. Treasury says applications for the first round are expected to open later in 2026 and a second round in mid 2027, with guidelines released before applications open. A state owned water utility is an eligible applicant. So is a regional council.
The part that changes a decision
The Abbot Drive site is a few hundred lots in a country town, and it would be easy to read it as a regional infrastructure story.
It is better read as a pricing story.
SA Water’s own charter makes facilitating greenfield property development a board responsibility, delivered by investing in the water and wastewater infrastructure that supports new customers. That responsibility is real. It is also funded in four year blocks by a regulator, on a cycle that has nothing to do with when a rezoning lands or when a builder needs the lot.
For anyone assessing land anywhere in Australia, the question has moved. It is no longer whether the site is zoned and approved. It is whether the trunk capacity serving it was funded inside the utility’s current determination, and if it was not, which determination it falls into and when that determination gets made. Those dates are public. In South Australia the answer arrives in 2028 for the period to 2032. In Victoria, June 2028 for the five years after. In New South Wales, August 2027 for developer charges.
Holding costs do not pause while a technical analysis runs.
Frequently asked questions
SA Water advised the developers in May 2026 that it was still completing a technical analysis of how future demand could be accommodated on the network, and was therefore unable to confirm whether sufficient capacity exists or what augmentation would be needed. Separately, SA Water has said its current four year funding cycle prioritises the Greater Adelaide Region under the state Housing Roadmap, and that there is no funding capacity within that roadmap to upgrade networks outside priority areas.
It is a decision by a state economic regulator setting the maximum revenue a water utility may recover from customers over a fixed period, usually four or five years. That revenue cap effectively sets how much growth infrastructure the utility can build in that period and where it goes. If the trunk water or sewer capacity serving a site was not funded within the current determination, the site can hold a valid rezoning and development approval and still be unable to connect until a later period.
No. SA Water’s augmentation charge applies to development approvals in the Greater Adelaide Region. Since 1 July 2024 the residential greenfield rate has been a fixed $10,000 per dwelling, split evenly between water and wastewater, with apartments, build to rent, community and not for profit housing exempt. Outside that region the charge is not levied, and the metropolitan growth investment program it helps fund does not extend there either. SA Water also states that where the charge applies it is in addition to any separate requirement to fund augmentation needed to service a specific development.
In South Australia, ESCOSA is making the determination for 1 July 2028 to 30 June 2032, with final submissions on methodology requested by April 2027 and the expenditure assessment running to March 2028. In Victoria, the Essential Services Commission’s 2028 Water Price Review takes price submissions from 16 water businesses at the end of September 2027 and issues final decisions in June 2028 for prices from 1 July 2028. In New South Wales, IPART’s review of developer charges for Sydney Water, Hunter Water and Central Coast Council is due to produce a position paper in December 2026, a draft report in April 2027 and a final report in August 2027.
It is a $2 billion Australian Government program announced in the 2026-27 Budget, funding local governments and state owned utilities to build the connections that enable new housing, including water, wastewater, stormwater, road and electricity infrastructure. A portion of the funding is reserved for regional areas. Treasury states that applications for the first round are expected to open later in 2026, with a second round expected in mid 2027, and that guidelines will be published before applications open. Applications will be made through the Business Grants Hub.
