If you are in Melbourne I would present at the Alfred Hospital. They have a public program and have specialist surgeons on staff 24/7. Being a public hospital you won't be charged. I had lap band done in the public system through the Alfred and after getting gastro (from work) and having the band slip and erosion had the band removed after 6 years. I will admit that I was going well sitting at about a size 10 and happy. Once the band was removed blew out to 125kg again. I have now has the sleeve (unable to do another band due to erosion) and down to a size 10 again. All my surgeries covered under medicare and if when I was unwell presented at casualty and was always seen. I was advised not to bother with a ny other emergency departments - just go to the Alfred Emergence Department. Wishing you the best of luck.
