A teenager diagnosed with a deadly brain tumour has raised $80,000 needed upfront to pay for urgent surgery. Jackson Byrnes, 18, has flown from Lismore in northern New South Wales to Sydney to be operated on by renowned neurosurgeon Dr Charlie Teo, the only surgeon in Australia willing to perform the risky operation that will likely see Jackson paralysed. For the past week Jackson's family and friends have been desperately trying to raise $80,000 needed to pay the hospital upfront by Tuesday night, so that he can undergo the operation on Wednesday morning. On Monday morning they reached the target on their GoFundMe page, but Jackson's mother says the family needs an additional $45,000 to cover chemotherapy and other hospital fees. Three weeks ago the 18-year-old was told by doctors that he had a stage four brain tumour that was too deep and aggressive to be safely operated on. Jackson Byrnes, 18, has flown to Sydney for a risky operation to remove the tumour on his brain . For the past week Jackson's family and friends have been desperately trying to raise $80,000 needed to pay the hospital upfront for the risky surgery . Jackson's girlfriend Jahnae Jackson (right) noticed he had developed a lump three weeks ago and prompted him to visit a doctor who requested an MRI . His family refused to accept the dismal diagnosis and took matters into their own hands and found Dr Teo, who said he was willing to perform the operation if the family understood the risks. Jackson's mother Rhonda Byrnes said Dr Teo explained to her that  her son would most likely be paralysed down his left side. 'But he's already paralysed because the tumour is pressing down on that side of his brain, that's why we've just said go for it,' Ms Byrnes told Daily Mail Australia. 'I can't afford not to because I won't have my son around if I don't take these risks. 'Dr Teo is the best brain surgeon in the country, I've got my son's life in his hands basically.' Dr Teo, director of Sydney's Centre for Minimally Invasive Neurosurgery, said other surgeons were technically able to perform the surgery but he was the only one prepared to do it. 'People think that it's futile because he's got a malignant tumour and it's very aggressive,' Dr Teo told Daily Mail Australia. 'There's significant weakness down his left side and they think his quality of life is such that he wouldn't want to live anyway.' But Dr Teo said he makes decisions based on what his patients want. 'If a patient really wants it and knows the risks and understands how risky the operation is I'll usually respect the patient's wishes,' he said .

Jackson's mother Rhonda Byrnes said she was overwhelmed by the support and money raised by the community on his GoFundMe page, but said the family still needed more . 'He is a lovely boy and he's only young. 'I said "You know you're going to be paralysed", I've told him the worst case scenario. 'He understands that and he wants to live.' Dr Teo will try to remove 95 per cent of the tumour, which has extended to very sensitive part of the brain. 'If you can buy him time with surgery then the hope is you're going to get a good response to the chemotherapy and radiotherapy and a significant extension of time,' he said. 'Even if we could buy him six months of life the hope is we're going to come up with new treatment in that time.' Dr Teo said the $80,000 payment required for the surgery was standard. Jackson needs  $80,000 by Tuesday night in order to pay for his surgery upfront, and another $45,00 for fees . Renowned neurosurgeon Dr Charlie Teo is the only surgeon in Australia willing to perform the risky operation that will likely see Jackson paralysed . 'I operate at a private hospital and they insist on upfront payment, you can't blame them they run it like a business,' he said. 'I don't know how much it costs I don't try and talk about the money side of things. 'But that is the cost of everything and it's also an insurance for the hospital should he get complications.' Jackson's mother Rhonda Byrnes said she was overwhelmed by the support and money raised by the community on his GoFundMe page, but said the family still needed more. 'It's amazing that we did it in four days,' Ms Byrnes told Daily Mail Australia . 'But I need more money because $80,000 is just for Dr Teo. 'The hospital fees are another $45,000 and I have to pay for MRIs and CT scans, all the radiation and chemo treatment.' Dr Teo will try to remove 95 per cent of the tumour, which has extended to very sensitive part of the brain . Taking to his Facebook fundraising page - Jackson Byrnes Brain Tumor Surgery Fund - friends of Jackson thanked the thousands of people who have made donations to the page. 'Overwhelmed with joy and gratitude,' the page posted on Monday morning. 'Thank you to everyone that contributed to this and more. Over 12K was also raised in the last week by local community.' According to the Gold Coast Bulletin, Mr Byrnes' girlfriend, Jahnae Jackson, noticed he had developed a lump  three weeks ago and prompted him to visit a doctor who requested an MRI. He was rushed to the Gold Coast for a biopsy which found a stage four tumour buried deep in the teenager's brain. Mr Byrnes was told they would not operate due to how deep the cancer was, but instead suggested chemotherapy and radiation treatment. Messages of support and promotion of the cause have flooded social media for the Casino teenager . The donations have been coming in thick and fast since the GoFundMe page was created . Knowing that this was not enough, Mr Byrnes and his family searched for a specialist who would perform the dangerous procedure. They found neurosurgeon Charlie Teo who would operate on Wednesday as long as he received an upfront payment of $80,000 by Tuesday evening. The family then turned to social media and crowd sourcing in a desperate plea for donations. 'Most boys his age begin their journey into adulthood with hopes , dreams and anticipation of what lies ahead and excitement of the endless opportunities of what life will bring them,' Mr Byrne's fundraising page on GoFundMe reads. 'It is not a time to be enduring a fight for your life.' Victorian finance, leasing and risk management company Morris Finance have made the largest donation to the cause by pledging $2000.
