Micro algal bloom off SA persists as commercial fishers seek economic relief
The South Australian Department of Primary Industries' latest published situation update reveals oyster harvesting areas in American River, Port Vincent and Stansbury remain under precautionary closure, along with part of the commercial harvesting area for pipis around the mouth of the Murray River.
South Australia's deeper shelf waters remain between 0.5 and 1 degree Celsius higher than the average for the time of year.
The report also showed that levels of chlorophyll-a (chla) had begun to reduce along the Coorong coast, but remained high in the north-east area of Gulf St Vincent.
The Marine Fishers Association (MFA) has approached the state government for licence fee relief for affected commercial operators.
Chief executive officer Pat Tripodi said the recent short patch of stormy weather seemed to have dispersed the bloom to different areas.
"Previously it was concentrated to the western side of Gulf St Vincent, and then after the storms it's come across to the Adelaide side and pushed up the top near [Port] Wakefield and up near Port Parham," he said.
Mr Tripodi said as soon as bloom-affected water entered a fishing area the prospect of fishers making catches disappeared.
Mr Tripodi said the MFA had written to SA Primary Industries Minister Clare Scriven to request fee waivers for those affected but was still waiting for an official response.
He said some members would be eligible for a $1,500 grant from the government's drought relief fund, given the link between drought conditions and the algal bloom.
In a statement, Ms Scriven said she was "open to discussing potential options" with the MFA.
"While some marine scalefish fishery licence holders are reporting significant impacts from the current harmful algal bloom, others are reporting no impact at all," she said.
"For this reason, various options may be explored."
Mr Tripodi said his members were "absolutely concerned" about the future of South Australia's fisheries, particularly in some of the hardest-hit areas around the Yorke Peninsula and Kangaroo Island.
"We're talking about all the shellfish that live in sediment, the worms, mussels, cockles, razorfish — they're gone.
"Even once this algae clears, our question is what [are] the fish going to come back to eat?"
Brad Martin from Oz Fish, who has been tracking the marine deaths caused by the bloom for months, said coasts along the Yorke Peninsula still seemed to be quite significantly impacted with reef and seagrass fish still washing up.
Mr Martin said there also had been a "trickle of fish mortalities" along the Adelaide metropolitan coast on the other side of Gulf St Vincent.
He said the bloom had grown in some areas and diminished in others, and was an "ongoing, dynamic situation", and it was not known when it would disappear.
Mr Martin said South Australia was experiencing more still, sunny days than would normally be expected at this time of year, continuing the conditions beneficial for the bloom.
One of the areas worst affected by the bloom before the cold fronts arrived in June was the waters between the northern coast of Kangaroo Island and Yorke Peninsula.
Tourist operator Roanna Horbelt of RAD KI said the conditions had continued to improve after the most recent cold front, and she was no longer finding any dead marine life on the beaches but was still seeing some of the foam associated with the algae.
But she said commercial fishers in the area were still concerned about a lack of catches in the future.
Ms Horbelt said she was now working with Professor David Booth from the University of Technology in Sydney to try to help gauge the impact the bloom has had on the iconic leafy and weedy sea dragon populations.

SA government offers financial lifeline to disability employment provider Bedford
Disability employment provider Bedford will avoid entering voluntary administration for now, with the state government offering a $15 million lifeline to the organisation. Bedford had flagged on Thursday that it would enter administration on Sunday unless it was given a financial lifeline. Premier Peter Malinauskas said a "comprehensive" rescue plan has now been developed to "stave-off" the organisation going into administration. Bedford has 22 sites across Adelaide and regional South Australia. It is understood the organisation employs over 800 staff and supports 1,400 people living with a disability.

Green paddocks mask reality of communities still very much in drought
After winter rain finally arrived, puddles formed in tractor tracks besides green grass on Chris Rowntree's property in Myponga, South Australia. ( ABC News: Sarah Maunder ) Rain has returned to farming regions in South Australia. But the drought is not over — it just looks like it. A carpet of grass is again coating the paddocks of Chris Rowntree's property in Myponga on the Fleurieu Peninsula, south of Adelaide. In some places, puddles and mud are even lining the ground. But looks can be misleading. "It is deceptive," dairy farmer Chris says. Despite the arrival of the winter rains, including hefty falls this week, Chris says his farm is still in drought. It's been a while since Chris Rowntree had to contend with puddles and muddy boots. ( ABC News: Sarah Maunder ) Grass has started to sprout after winter rain finally arrived. ( ABC News: Sarah Maunder ) But dairy farmer Chris Rowntree says the green masks the reality. ( ABC News: Sarah Maunder ) Large parts of SA and Victoria, as well as parts of Tasmania — the home for a lot of Australia's wine, grain, meat and dairy production — remain at their lowest rainfall on record for the last year and a half. For some, it's gone on for even longer. In the 17 months from February to July this year, some areas have experienced their lowest rainfall on record. Beyond the muddied boots, there is a convoy of trucks full of hay still rolling in from the other side of the Nullarbor in Western Australia. Livestock are still being hand-fed daily. Producers are still stretched thin and worn down. "We're probably lucky that at least we've had rain," Chris says "But if you look closer and drive through the paddocks, there are areas that are very thin in pasture, and growth rates are being very poor." The sun sets over the gated path on Chris Rowntree's property in Myponga, South Australia. ( ABC News: Sarah Maunder ) It's what's known as a "green drought". The rain may have come, but in many cases, it's arrived too late. Cold is now hindering the growth of plants. "Most people would know that their lawns in the middle of winter don't tend to do a lot, and that's what's happening on the whole farm," Chris says. It's not just the late arrival of the rains this year. Since spring 2023, the rains have stopped early and arrived late. It's left pastures dead or stressed, and the ground thirsty for every drop that falls. Due to the late rain, Chris Rowntree still has to handfeed his cattle. ( ABC News: Sarah Maunder ) The fine layer of grass has not been substantial enough, and feed trucks keep delivering to Myponga. ( ABC News: Sarah Maunder ) Chris's paddocks are still reeling after a lack of rain the year before. ( ABC News: Sarah Maunder ) Myponga is one of the wettest parts of the state. Still, Chris and his wife, Bev, have to purchase the majority of their feed — something that is now scarce in South Australia because of the prolonged dry. "Between that May period and now, it's about nine semitrailer loads of feed that we've had to purchase that we normally wouldn't. Which is, yeah … quite a lot," he said. Fifteen minutes north, in Hay Flat, the trees show the reality beneath the thin veneer of green. "In about March this year, I noticed a number of trees, including quite large trees, with their leaves going brown and dying off," Hay Flat property owner John Dallwitz says. "Normally in late summer, one gets a certain amount of die-off … but this year, it seemed worse than usual or more than usual." He's worried for some of the older eucalyptus trees on his property, which are showing severe signs of stress. "It's devastating," he says. But the rains brought life back for at least some. "That's alive," John says, as he scrapes back the bark of a tree. "That's nowhere near dead. So I'm very thankful that my 200-year-old, 300-year-old tree is going to survive." Many trees on John Dallwitz's bush block in Hay Flat won't come back. ( ABC News: Sarah Maunder ) John is particularly worried about some eucalyptus trees which are hundreds of years old. ( ABC News: Sarah Maunder ) John Dallwitz shaves off some bark from a tree trunk. ( ABC News: Sarah Maunder ) Green beneath the bark of trees makes John hopeful that some of the trees will survive the drought. ( ABC News: Sarah Maunder ) He's not the only one with these concerns. An hour east, botanist and ecologist Dean Nicolle grows over 800 species of eucalyptus at the Currency Creek Arboretum. He estimates between 10 and 20 per cent of all the eucalypt species that are planted at the Arboretum are going to die or be "severely drought impacted". "We're hoping that with the rain we've had now, that some of these plants will re-sprout, but a lot of that will depend on conditions going forward," he says. The flow-on effects of the drought are felt by all in the town of Langhorne Creek. ( ABC News: Sarah Maunder ) Nearby, in Langhorne Creek, Beck Burgess deals with the deception of the green drought every day. She is a farm consultant but also owns a microbrewery just out of town. "The frustration for me is when we did have people coming to our bar and saying 'the drought is over,'" she says. "Even if it does look green, there's still very challenging times for producers." Beck Burgess is keen to dispel the myth the green landscape means the drought is over. ( ABC News: Sarah Maunder ) She says the realities of the harsh seasons are seeping through all parts of the community, including their own business, where the price of raw ingredients needed for beer — like hops — has gone up. "There's a roll-on effect when [people in] agriculture in these rural areas are unable to contribute to their local economy," she says. "So the local shopfront is affected, the tractor dealership's affected, local shearers, all the like … but also the local businesses as well. "People we know won't necessarily be spending the same amount of money within the townships as well." Even though things are bad, people in this part of the state are aware that it could be worse. South Australia's outback has been heavily impacted by drought. ( ABC News: Che Chorley ) In regions to the north and east of Adelaide, there's nothing green about the drought. While rain has been reaching the southern regions since late May, it has all but missed areas to the north and east of Adelaide. Steph Schmidt, who farms crop and livestock in the Mid North and Mallee regions, says the landscape has changed very little from the scenes of dust storms and brown dirt in June. Being a psychologist as well, farmer Steph Schmidt (with her sons) knows how deeply communities are affected by the ongoing drought. ( Supplied: Stepth Schmidt ) At her property in the Mallee region, their crop now has to be re-sown, after being "blown out of the ground or covered up". "Across the majority of our farm, it's still really in drought drought or brown drought, whatever we want to call it," she said. "Lots of the neighbours [at our Mallee property] have said the last couple of years were some of the worst on record, but we still had crops come up and still grow. "Whereas this year, talking to some of the neighbours, they're saying it's the worst they've ever seen. It's completely bare." The Mallee region is still very much in "brown drought". ( Supplied: Steph Schmidt ) Sandstorms and brown dust still dominate the landscape. ( Supplied: Steph Schmidt ) This weekend's rain is more than welcome. Steph describes it as being like a "lifeline" to people who have been worn down for several years. "I think it would be a breather more than anything," she says. But like those in the south, it's come too late to make a substantial difference. As a psychologist, Steph knows too well how much of a toll the back-to-back seasons of dry are taking. "It's exhausting," she says. "I think the hardest part of the drought is that there is so much uncertainty. We never know when that recovery is actually going to get started." The contrasting situations, from one end of the state to the other, speak to the nuance of drought. Farmers have learned to adapt to changing environments. ( Supplied: Chris Rowntree ) Monash University climate scientist Ailie Gallant in many cases, the timing of rainfall is everything. "There are no official definitions for drought. In fact, there are hundreds of different definitions for drought, and it really depends on the perspective from which you're looking at," Professor Gallant says. "Farmers, they know when they're in drought. And I think we should trust those on the [land] to realise when those systems are in stress and when they need help." She said the changing face of drought could also give a false sense of relief. But she says a drought is only truly over when big and persistent rains have replenished the streams, rivers and soil moisture enough that it can be sustained. A few rain events and a couple of puddles may give false hope. ( ABC News: Sarah Maunder ) A lack of rain during the critical growing season is one of the hallmarks of climate change for this region. Cold fronts and low-pressure systems rolling in from the west, which used to be a weekly occurrence, have become more sporadic. "So that is certainly an ongoing trend that is on top of any droughts and things that we might get," Professor Gallant says. Farmers in the region, who have learned to live at the mercy of extreme weather for generations, are already adapting to that future. Chris Rowntree is grateful he had at least some rain on his farm. ( ABC News: Sarah Maunder ) His dog looks hopeful that the rain will keep coming. ( ABC News: Sarah Maunder ) For now, there is some more hopeful news on the horizon. The long-range forecast indicates early spring could deliver higher-than-average rainfall to much of the east — the very thing farmers are hoping for. In the meantime, drought-weary farmers say consumer buying Australian produce and government providing further funding for low or no-interest loans will help. Steph Schmidt wants to remind communities in the thick of it that they will make it through. "For people who are living it, I just like want to share the reminders that we will get through to the other side of it."

Heavy rain and blizzard conditions to stick around for the weekend in several states
Severe weather warnings are in place for several states this weekend with heavy downpours, intense wind gusts and blizzard conditions. A large rain band moving across Australia brought soggy conditions across large parts of the country, stretching from much of central Queensland to Tasmania and over to coastal areas of South Australia. Queensland copped an "unseasonable" amount of rain including in the central highlands, where 45 millimetres was recorded in the 24 hours to Saturday morning, Bureau of Meteorology senior meteorologist Angus Hines said. South Australia received a much-needed soaking after 18 months of below-average rainfall, with the Mount Lofty Ranges recording 40mm-60mm. "The rain that they've seen in the past 24 hours has been really bucking the trend of recent months," Hines told AAP. It brought blizzard conditions to popular alpine areas in NSW and Victoria, sparking alerts for travellers hitting the road. The state's dry west also received a drenching, with the Grampians recording falls of about 60mm. The bureau also warned of blizzard conditions in NSW alpine areas with peak gusts up to 100km/h in the Snowy Mountains on Saturday, including the lower resort slopes at Perisher and Thredbo. The NSW National Parks and Wildlife Service recommended back country travel be postponed until conditions improve. Hines said winds in both states had the potential to bring down trees, damage properties and cause power outages. Some 42mm fell in just four hours on Saturday morning at Gray in Tasmania's northeast after a similar amount fell in the previous 24 hours. Emergency services are keeping an eye on rising rivers. "Reduced visibility in heavy rain, with possible water over roads will make road conditions dangerous," the bureau said. Queensland and Tasmania were expected to cop the most rain late on Saturday before conditions ease on Sunday. "It's going to stay quite wintry because it will be chilly, cold temperatures, quite gusty winds, sort of showers, possibly some hail in there as well," Hines said. The next burst of national soggy weather is already forming across West Australia and will hit Perth from about noon on Sunday.
