Help Dr John Mackeral Medivac to Brisbane

Hi. My name is Sally. Dr Mackeral is a very close family friend and my local GP who osteomyelitis and risks a high chance of having his foot amputated if we do not seek urgent medical help in Australia. He currently lives in Madang, Papua New Guinea and the current situation of under resourced hospitals cannot cater to his needs. Any help to raise enough money to pay for his Medivac which will cost around PGK100'000.00 equivalent to AUD$50'000.00 would be sufficient to get him the urgent care he needs.
