Heavy rain lashes the east coast as vigorous coastal low intensifies off NSW
The complex and rapidly deepening system was expected to slowly track southwards, approaching the central NSW coast later on Tuesday before turning and moving offshore into the Tasman Sea on Wednesday, according to the Bureau of Meteorology.
The NSW State Emergency Service had already deployed vehicles, helicopters and personnel to areas likely to be heavily impacted.

A severe weather warning was in place for people in the Mid North Coast, Metropolitan, Northern Tablelands and parts of Northern Rivers, Hunter, Illawarra, South Coast, Central Tablelands and North West Slopes and Plains districts.
Weather warnings were issued for Taree, Newcastle, Gosford, Sydney, Wollongong and Port Macquarie
The mid north coast region is an area of concern for emergency services because of the soil is still saturated from the May floods.
Bureau meteorologist Helen Reid said the wind and rain was likely to increase into the afternoon and overnight.
With the rain continuing, some places along the coast could reach over 100mm of rainfall, and 'even a couple that might get up to the 200mm mark', Reid said.
By 7.30am on Tuesday, Jervis Bay had recorded 109mm, Currarong 85mm and Williamtown 70mm. Several places in the Northern Rivers had already seen 40mm of rainfall, she said.
The bureau was also warning of destructive winds averaging 60 – 70km/h, with peak gusts of up to 125km/h possible.
'Winds could bring down trees or tree limbs, lead to dangerous driving conditions due to crosswinds or debris being thrown across the roads, and lead to power outages and possible damage to cars and property,' Reid said.
Conditions were expected to be treacherous on the water from Seal Rocks to Batemans Bay, with the potential for waves up to seven metres, and could cause coastal erosion and possible inundation of low-lying areas along the eastern foreshore.
Damaging surf was also forecast for an area of coastline from Forster to Moruya Heads, including parts of Hunter, Metropolitan, Illawarra, South Coast and Mid North Coast Forecast Districts. Conditions could lead to coastal erosion and damage to coastal infrastructure.
Widespread heavy rainfall could cause flooding. Although there was some uncertainty over the exact location and timing of the heaviest falls.
Catchments likely to be affected included: Wallis Lake, Myall River, Wollombi Brook and Lower Hunter River, Upper Nepean River, Hawkesbury and Lower Nepean Rivers, Upper Coxs River, Colo River, Macdonald River, Northern Sydney, Southern Sydney, Parramatta River, Cooks River, Georges and Woronora Rivers, Illawarra Coast, St Georges Basin and the Snowy River.
The SES urged people to be vigilant, and to prepare by tying down any loose items, to avoid them becoming projectiles.
'We are encouraging communities to start preparing their homes,' SES deputy commissioner, Debbie Platz said on Monday. 'It's really critical that you clean your gutters, that you move items that are loose … such as trampolines and outdoor furniture, tie them down or move them to a secure location.'
'Please move any vehicles that you have away from any large trees,' she said.
'On Wednesday, the focus for the rain will shift further south, scattered showers and rain areas will still impact the east coast, between the mid north coast to the Victorian border, but the heavier falls will be focused through the Illawarra and the northern parts of the southern coastal district,' Reid said.

Nearly one in five NSW trains ran late in past year, falling well short of own performance target, data shows
Sydney Trains have hit a new low for on-time services with only 82.5% of trains arriving within five or six minutes of scheduled times over the last year. The result, based on data in the year to 30 June, represents a significant slide in performance from the previous year, when 87.9% of trains ran on time. The New South Wales government aims for 92% on-time running, with punctuality defined as running within five minutes of scheduled times for suburban trains within the Sydney metropolitan area and six minutes for intercity trains. 'Whilst Sydney Trains did not reach its own 92% performance target over the past three years in part due to protected industrial action during this period and severe weather events, on-time running in 2022 was 92.1%, 95% in 2021 and 92.5% in 2020,' a spokesperson for Sydney Trains told the Guardian. 'On-time running or punctuality can also be impacted by other unforeseen factors, including fatalities, sick passengers, trespassers, police operations, and maintenance requirements,' the spokesperson said. Sign up: AU Breaking News email The transport minister, John Graham, said: 'Settling the rail agreement means all energy can now be focused on reliability. We have got that message loud and clear.' Punctuality was particularly bad for intercity trains, which include the Newcastle and the Central Coast, Blue Mountains, South Coast and Southern Highlands (Goulburn) lines. Only 70.5% of those trains recorded on-time running. Sydney CBD trains did better, with 84% arriving on time. For the Blue Mountains, the last financial year was the worst on record, with just 69% of services running on time. For the Central Coast, it was also the worst on record, with just 68.7% of services running on time. There are no signs of improvement on either line in the first weeks of July, according to data. The Southern Highlands line is showing signs of improvement but off a very low base of only 60% on-time running. Protracted negotiations with the Rail Tram and Bus union over a new enterprise agreement, which resulted in strikes and work bans, affected the network during the period. Sydney, the Central Coast and the Illawarra were also hit by torrential rain on several occasions including in January, May and June. The opposition leader, Mark Speakman, accused Labor MPs in the Blue Mountains, Central Coast and South Coast of being 'nowhere to be seen' on the deterioration in service. Sign up to Breaking News Australia Get the most important news as it breaks after newsletter promotion 'Chris Minns, John Graham and every Labor MP in these areas should ride the trains their communities are forced to suffer,' he said. 'If they did, they'd see the delays, the breakdowns, the frustration – and they'd know just how badly they've failed. The truth is Labor thinks they can take these seats for granted.' In response, Graham said 'it was a much simpler task for government running a train network when it was also asking the population to stay behind a locked front door during the pandemic. 'The Liberals understand the challenge because under them on-time running fell to an all-time low of 71% in one month in 2022 and the 92% target was missed in 10 of their last 12 months in office,' he said. Sydney Trains said it had introduced several initiatives to increase reliability of services and enable the network to recover faster from disruptions, such as an adjusted timetable in October 2024 that saw some stations receive increased service frequencies, a new intercity fleet on some lines and a train repair plan. The poor train results come as the state government announced it was shedding 950 jobs from the department, Transport for NSW. It is believed the cuts are not to front line jobs.

‘Devastating' toxic algal bloom declared natural disaster in Australia amid warnings Bondi beach could be next
South Australia has declared its toxic algal bloom a natural disaster following weeks of pressure from scientists, local officials and community members over what has been called an 'unprecedented' marine crisis. The bloom – fuelled by the toxic algae Karenia mikimotoi – has devastated marine life along more than 500km of the coastline since March, killing thousands of fish, rays, sharks, and dolphins, and threatening local fisheries and coastal livelihoods. South Australia premier Peter Malinauskas described the bloom as a natural disaster that 'should be acknowledged as such' and urged leaders not to get 'caught up in technicalities'. 'This is so entirely unprecedented we don't really know how it's going to play out over coming weeks and months ahead,' he told ABC's News Breakfast, noting over 400 marine species had been impacted. Federal environment minister Murray Watt visited some of the affected areas this week and pledged a $14m assistance package but said the event did not yet meet the criteria for formal natural disaster status. South Australia, however, invoked state authority to make its own declaration, unlocking additional emergency support. Marine experts have been sounding the alarm over the crisis for months. In May, conservationists said the boom had already killed over 200 marine species. 'It's hard to overstate the extreme severity of the algal bloom environmental crisis in South Australia,' Adriana Vergés, a marine ecologist at the University of New South Wales, said. 'We are talking about extensive mortality of nearly 500 different marine species, including key habitat-forming sponges and other invertebrates, as well as fish over more than 500 km of coastline. It's completely devastating.' Described as a 'toxic blanket', the bloom suffocates fish by damaging their gills and attacking their red blood cells and the nervous system. It can lead to haemorrhaging and erratic behaviour in the affected animals. Photos from beaches around Adelaide show carcasses of snapper, stingrays and other dead sea creatures lining the shore. According to local records cited by The Guardian, over 13,800 animals are confirmed dead but the real toll is likely far higher. Professor Shauna Murray, a harmful algal bloom expert at the University of Technology Sydney, said the bloom had impacted several hundred square kilometres of coastline since mid-March and was now impacting Adelaide, a city of 1.5 million. She warned that brevetoxins – neurotoxins produced by the algae – had already been detected in some seafood. 'It's not just having an ecologically disastrous effect, it's now severely impacting fishing and aquaculture industries as well as tourism. We need regular monitoring and financial support for all affected,' she said. The crisis has already led to the closure of Coorong's pipi fishery and parts of the state's oyster aquaculture due to health concerns. Scientists warn that less mobile species, like seahorses, flatheads and leatherjackets, may take years to recover. John Morrongiello, associate professor at the University of Melbourne, described it as 'an ecological catastrophe' that could have long-term consequences for marine food webs and coastal economies. Climate and nutrient pollution are believed to have played a role in the crisis. Scientists say it is being fuelled by an ongoing marine heatwave, with sea temperatures 2.5C above average, and calm conditions that allow it to thrive. 'This is climate change in real time,' Dr Nina Wootton from the University of Adelaide said. 'The consequences of years of inaction are now unfolding before our eyes.' The algae species behind the toxic bloom has traits that may explain its unusual scale and persistence, according to scientists. 'This species of algae has several adaptations that may have enhanced its ability to grow in the context of the South Australian blooms,' professor Perran Cook from the School of Chemistry at Monash University said. 'It can 'swim' up and down in the water column, which allows it to take up nutrients from the deeper layers of water when there is little mixing, as has been the case in the waters off South Australia this year,' he explained. 'The warmer conditions typically favour most algal growth, and this species is no exception. It also has a wide temperature tolerance, which might help explain its persistence into winter.' Dr Cook noted the algae's ability to 'assimilate the 'remains' of other algal blooms' could link it to the 2023 Murray River floods, which 'released vast amounts of nutrients that stimulated algal growth then, and it is possible that these nutrients are still rippling through the food web.' Greens senator Sarah Hanson-Young said the $14m assistance announced by the federal minister was just a 'downpayment' and criticised the government for failing to declare the crisis a federal emergency. Speaking in the parliament, she warned that such events were becoming more likely due to the climate crisis. 'It's Adelaide beaches today but it could be Bondi tomorrow,' she said, calling for a parliamentary inquiry into the bloom and the introduction of a 'climate trigger' in Australia's environmental laws. In response, prime minister Anthony Albanese said the government's support was timed 'appropriately' given the event was unfolding primarily in state waters. 'What is important is that there be a response,' he told ABC's 7.30 show. 'We are responding, giving support to the South Australian government.' Dr Christopher Keneally from the University of Adelaide said the toxic bloom's scale, potential to cross state boundaries and long-term ecological legacy placed it 'on par with the bushfires and floods that routinely trigger federal interventions'. 'This is not just an environmental event – it's an ecological disaster,' added Dr Lucille Chapuis, a marine biologist at La Trobe University. 'Like a bushfire or floodwater, a toxic bloom can sweep through an ecosystem, and we must treat it with the same urgency.' Scientists are calling for a national response strategy and long-term investments in monitoring and early warning systems for such events. 'We cannot just treat this as a one-off event that should be monitored. This is a complex problem and we need a coordinated science–industry–governance response,' professor Martina Doblin, director of the Sydney Institute of Marine Science, said.

Toxic algae bloom off South Australia devastates marine life, tourism
SYDNEY, July 22 (Reuters) - A massive outbreak of toxic algae off South Australia, which has devastated hundreds of species of marine life and disrupted local tourism and fishing, is a "natural disaster," state Premier Peter Malinauskas said on Tuesday. The algal bloom, first detected in March, spans an area 4,500 square km (1,737 square miles) in size and has been aggravated by rising ocean temperatures, according to environment officials. 'There are over 400 different species of marine life that have been killed off or have had deaths as a result of this algal bloom,' Malinauskas told national broadcaster ABC's News Breakfast program. 'This is a natural disaster and should be acknowledged as such.' Malinauskas announced a A$14 million ($9.11 million) support package to tackle the outbreak, matching a package by the federal government. The combined A$28 million would assist with clean-up efforts, research, and business support. The toxic bloom has been caused by overgrowth of the Karenia mikimotoi algal species, which affects fish gills and sucks oxygen out of the water as it decomposes, the state's environment department said. Contributing to its growth was a marine heatwave that started in 2024, when sea temperatures were about 2.5 degrees Celsius (36.5 degrees Fahrenheit) warmer than usual. The bloom has impacted tourism and forced oyster and mussel farms to temporarily shut due to a waterborne toxin caused by the algae, local media said. Over 13,850 dead animals, including sharks, rays and invertebrates, have been recorded by the public on the iNaturalist app. Federal Environment Minister Murray Watt said on Monday the algal bloom was a "very serious environmental event," but stopped short of declaring it a national disaster, which would allow for greater federal support.
