Our water bills are too cheap – and we'll soon pay dearly for that
Playing out across Australia, and particularly Sydney, is an issue that profoundly affects both of these challenges, and it has been building for the past decade. Like new roads and energy infrastructure, new water and wastewater pipes and infrastructure must be built to accommodate new housing.
NSW Treasurer Daniel Mookhey has described the years ahead as the decade of pipes and poles. Data centres, the new building block of productivity, need secure water sources just as much as they need energy and land. Data centres of the future will be among the biggest water users in any capital city in Australia, and dozens are expected in major cities over the next decade.
In Sydney, against a backdrop of criticism for not keeping pace, Sydney Water has proposed to spend $15 billion over five years to maintain ageing infrastructure, meet the housing needs of a rapidly growing city and ensure a resilient and secure supply of water.
However, in its draft decision, the NSW pricing regulator, IPART, has proposed a cut of $5.9 billion, or 35 per cent, over the next five years – one of the largest cuts to proposed water investment we've seen for a generation. IPART's draft determination has cut investment for housing-related infrastructure by $3.2 billion over those five years compared with what Sydney Water proposed.

Like many others, the Water Services Association of Australia, which I lead, has raised concerns that delaying investment risks a lack of new water and wastewater connections placing a handbrake on housing and productivity in Sydney. While Sydney is the focus of friction now, we've been highlighting for some time the funding constraints that exist across the industry.
The National Performance Report for the urban water sector was released this year by the Bureau of Meteorology. It went unreported in the media. It shows two contrasting trends over the past decade: first, bills for water and wastewater services have remained flat; second, investment has been significantly increasing – water and wastewater capital expenditure during that period roughly doubled.
The flat bill trend is not sustainable. A step change in capital expenditure is required, with investment for housing being the biggest driver.

EVs may be the way to drive down everyone's power bills
Incentives for electric car owners to sell energy stored in their vehicles back to the grid could deliver a $230 million national windfall and make power cheaper for everyone. Modelling by the Electric Vehicle Council suggests a $3000 government rebate towards vehicle-to-grid, or V2G, chargers would create $4500 in downward pressure on electricity bills Australia wide. So called bi-directional technology allows energy stored in EVs during daylight hours and while power is cheap to be sold back during evening peaks. According to the research, every dollar spent supporting V2G would mean a $1.50 return through lower wholesale prices and a reduced need for additional expenditure on infrastructure. The benefit for participating EV owners would be handy too, with an extra $1000 per year in their pockets for exporting power when demand is high. The council wants V2G chargers included in the federal government's $2.3 billion home battery program and says 600,000 contributing EVs would match the output of NSW's Eraring power station operating at full capacity. There is major potential to make electricity cheaper and help stabilise the energy grid, according to CEO Julie Delvecchio. "Just as Australia became a rapid global leader in rooftop solar, we have the opportunity now to lead the charge in vehicle-to-grid uptake," she said on Saturday. "EVs can store up to five times more energy than a typical home battery." Australia is already home to more than 350,000 EVs or "giant batteries on wheels", with a high proportion garaged in middle and outer suburbia. "With some EVs now around $30,000, the up-front cost is making it more affordable for more Australians to make the switch to cheaper-to-run cars," Ms Delvecchio said. "V2G unlocks the full benefit of EV uptake in a way that helps everyone - EV owner or not." The council is calling for the home battery program to include $3000 rebates for 50,000 V2G chargers by the end of 2028 at a cost of $150 million. It calculates this would create a national benefit of more than $230 million by 2033. A study conducted by the University of Technology Sydney and iMove Co-operative Research Centre earlier this year found more than half of all Australians would like their car to double as a battery that could feed power back to the grid. However big changes would be needed to make the process easier. The high price of bi-direction chargers, persistent software issues and complicated installation processes were cited as the main issues. The Australian Renewable Energy Agency issued a V2G roadmap in February that estimated 2.6 million households could be using the technology by 2040 to support the energy grid and save money.

‘Not going to tolerate' antisemitism: Bill Shorten outlines university's plan to combat ‘hate' following envoy report
University of Canberra's Vice-Chancellor and former Labor leader Bill Shorten has outlined the universities' plan to combat antisemitism on camps, saying 'we're not going to tolerate people being treated badly' due to their Jewish heritage. Australia's Special Envoy to Combat Antisemitism Jillian Segal handed down a major report on Thursday, just one year after the business executive was appointed to the role. Ms Segal ordered university chancellors and vice-chancellors to cooperate with her plan to stamp out antisemitism on campuses, or risk funding cuts. Following the recommendations announcement, Mr Shorten said he thought it was important to promptly take a stance on the matter, as 'Antisemitism is real'. 'It's not a creation of the right wing or Israel lobbyists, antisemitism is real. It's a centuries-old hate, and we thought it was all in the history books but now it's come out of the drains,' Mr Shorten told Sky News on Friday. In light of incidents such the alleged arson attack on a Melbourne synagogue last week, Mr Shorten said antisemitism needs to 'be called out' 'And Jewish Australians have got to know... we're not going to tolerate people being treated badly because they're Jewish,' he said. Pressed as to whether the University of Canberra will be implementing the special envoy's recommendations, the vice-chancellor said it will work with other universities and will ensure the safety of students with Jewish heritage on campus. 'I do not want people coming from outside the campus causing grief, and Australians of Jewish heritage have got to feel that when they come to the University of Canberra, this is a place where they can study, learn, be treated with respect,' Mr Shorten said. '... UC wants students of all faith, including kids of Jewish heritage.' Ms Segal's report outlines a series of measures needed in order to combat antisemitism, which it claimed had 'reached a tipping point that threatens social harmony, undermines trust in institutions and marginalises Jewish Australian citizens'. Ms Segal told Sky News host Sharri Markson on Thursday that she planned to delegate work for 'different parties', especially the federal and state government, and educational and cultural institutions. 'There's support I will need from the federal government, but also from state governments, also from leaders in society, leaders of cultural institutions, chancellors and vice-chancellors at universities,' Ms Segal said. 'I will be putting them to the task of supporting me when I need federal government support, but equally I'll be looking to state governments to support educational initiatives. 'I'll looking to universities to continue what has been very cooperative stance from them in moving towards initiatives to combat antisemitism on campuses.'
