What are the most common medical reasons for Australian visa rejection?

What are the most common medical reasons for Australian visa rejection relate to failing health requirement under Public Interest Criterion PIC 4005 and 4007, where Department of Home Affairs assesses if you have condition that is significant cost to community or threat to public health. Most common reasons include tuberculosis, active TB detected on chest X-ray or Quantiferon test, which leads to temporary refusal until treated and cleared. Second, HIV positive is not automatic rejection, but if it requires expensive antiretroviral treatment costing over $51,000 threshold over 10 years, it can be rejected for permanent visas under significant cost criterion. Third, hepatitis B and C with liver damage requiring treatment. Fourth, chronic kidney disease requiring dialysis or transplant, costing $80,000+ per year, exceeds significant cost threshold of $51,000. Fifth, cancer with ongoing treatment. Sixth, intellectual disability or developmental delay in child requiring substantial support and special education costing over threshold. Seventh, mental health conditions requiring extensive support. Eighth, failure to complete medical or provide additional tests. Public health threat like untreated syphilis or drug-resistant TB also causes refusal. For temporary visas, active TB is main reason. For permanent visas, significant cost is main reason, threshold $51,000 over 10 years or $86,000 over lifetime for some. You can apply for health waiver under PIC 4007 for some family visas if you show compelling reasons. So TB, kidney disease and high-cost chronic conditions are most common medical rejection reasons.
