Two people killed in devastating South Australia bushfire Two people killed in devastating South Australia bushfire Two people dead and toll expected to rise as 13 more were badly burned in catastrophic bushfire near Adelaide razed homes and incinerated TWO THOUSAND pigs Two people have been killed and there are fears for a third from huge bushfires raging near Pinery, north of Adelaide. South Australian Premier Jay Weatherill says 13 people are in hospital and five of those are either in critical or serious conditions with significant burns. One has burns to more than 80 per cent of their body and 'we do hold grave concerns for them,' Mr Weatherill said. It is believed that at least two of those injured were fighting fires. A 56-year-old woman from Hamley Bridge and a 69-year-old man from Pinery were killed on Wednesday. It has also been reported a third person may have also died, but it was yet to be confirmed The Premier said it was 'the worst news', and urged others to follow advice from emergency services to avoid further tragedy. The blaze has also destroyed homes and other buildings and has burnt through more than 85,000 hectares of cropping land. At least 16 homes have been destroyed, alongside outbuildings, vehicles and farm machinery. 'Further to this, a significant number of stock and crops have been lost, including a piggery with an estimated 2000 sows,' Mr Weatherill said. It comes after two firefighters have been injured as 'dangerous and fast moving' fires continue to burn across parts of South Australia. More than 350 volunteers, 68 trucks and eight aircraft are battling a blaze that started near Pinery, about 80 kilometres north of Adelaide. Country Fire Service South Australia said it is 'highly likely homes will be lost'. The fire is also racing towards the famous Barossa Valley wine region, which could put vineyards at risk. A stark photo of the threat was posted on social media, showing ominous dark skies looming over the famous Chateau Tanunda, which has been a icon of the area since 1890. Another heartbreaking picture showed property owners Jim and Lorraine inspect their destroyed house after devastating fires swept through the area. People were also evacuated from the valley, after heavy smoke and reports the fire front was about to jump across barriers and hit the area about 4pm. Homes and people in the Riverton, Eudunda, Marrabel, Pinery, Owen, Hamley Bridge, Freeling, Greenock, Kapunda, Nuriootpa and Dutton are under serious threat from the blaze, according to updated CFS warnings. It is believed the fire, which has a frontage of 41 kilometres and is moving at 12 km/h, will take days to get under control. 'This thing is going to go for some time, this is a particularly nasty fire... It's unlikely that we will have the fire contained for another few days,' CFS Chief Officer Greg Nettleton said, according to the Adelaide Advertiser. Mr Nettleton said in total 17 South Australian aircraft and two water bombers from New South Wales are being used to fight the fires. Victorian Premier Daniel Andrews also said on Wednesday night 200 volunteers and 50 trucks were heading to Adelaide on Thursday morning to help. It comes after a CFS spokeswoman told Daily Mail Australia two volunteers had been rushed to Adelaide Hospital after suffering burns on the front-line. Residents around Mallala, 55 kilometres north of Adelaide, and Lameroo, 200 kilometres east of the South Australian capital, have been warned to stay indoors to escape the fast-moving fires. Smoke filled the air above both towns as the fires are fanned by strong winds in the hot, dry conditions. Locals told of their horror as the fire closed in, forcing many to flee their homes and watch as properties around them burnt to the ground. 'Our house here and house and sheds here have survived, but every square inch of ground I think has been burnt,' Mallala farmer Peter March said, according to the ABC. 'We've got neighbours who haven't got any houses and haven't got any stock - we've got neighbours who are a lot worse off than we are.' Another man, who worked at a piggery, said staff were forced to flee and leave as many as 2000 pigs for dead. 'It was pretty scary seeing it coming over the hill coming towards work,' the man told the ABC. 'We were there with firefighters ready to fight it and we just turned and ran. It was big. I think my work's gone or at least the majority of it.' Two people killed in devastating South Australia bushfire
