What Is the Average Water Bill in Darwin?

Absolute Plumbing Australia • February 10, 2023

Australia’s Northern Territory, including the city of Darwin, is known for its hot climate and tropical landscapes. Unfortunately, water usage is a regular and necessary expense for Darwin residents. Water bills in the Northern Territory are charged quarterly, with the cost varying depending on the size of the property, how many people are living there, and how much water is used.


This blog explores the average cost of water in Darwin so that you can better understand your expected expenses when it comes to water usage. Whether you’re planning to live amongst the Top Enders or are already a local, this blog can help to give you an idea of what your water bills should look like.

Unveiling the Average Water Bill in Darwin

In Darwin, the average water bill is approximately $300-400 per quarter. This figure can range from slightly lower to much higher depending on various factors, such as how large your property is and how many people live there. For example, a family of four will use more water than an individual or couple living in the same house.


The Team Poly website advises that Darwin households can expect to pay $1.96 per kilolitre (1,000L) of water used. This figure is then multiplied by the total water used to calculate your quarterly bill.


It’s important to note that water bills in Darwin also include a fixed charge to cover the cost of maintaining and repairing the water infrastructure. This fixed charge is typically around $140-150 per quarter, regardless of how much water is used.

How to Lower Your Water Bill in Darwin

If you’re looking to reduce your water bill, there are a few steps you can take. Firstly, limit the amount of water your household uses by ensuring everyone is conscious about their usage. Try fixing any leaks or drips, adjust your showerhead for a lower flow rate, and opt for shorter showers rather than long baths.


The Northern Territory Government also offers rebates on water-efficient appliances such as dishwashers and washing machines. You may be eligible for plumbing discounts if you have a low or fixed income. With careful planning, it’s possible to keep your water bills at a reasonable level in Darwin.

Common Mistakes That Increase Your Darwin Water Bill

As much as it’s tempting to use more water than you need to cool down in the tropical heat, it’s essential to be mindful of your usage. Overwatering the garden is one of the main culprits; if you don’t have a smart irrigation system in place, it’s easy to overdo it and use more than necessary.


Another common mistake is using too much hot water. If you’re boiling the kettle multiple times a day or taking long showers with a high flow rate, this will add up quickly on your quarterly bill. Opt for shorter showers to reduce your hot water usage and consider switching to an energy-efficient showerhead.


Finally, be sure to check for any possible leaks around the house which could be causing unexpected increases in your water bills.

Not Sure Why Your Water Bill Is So High?

If there's no obvious explanation for why your water bill is so high, it might be worth contacting your local utility provider. They can help explain why your bill is higher than usual and advise you on any steps to reduce it.


While water bills in Darwin can be high due to its hot climate and tropical landscapes, there are ways to keep their cost at a manageable level. By understanding how they are calculated, taking the initiative to reduce your water usage, and being aware of any possible leaks or other factors contributing to the high cost, you can ensure your water bills remain manageable.
