From my experience, King Billy Casino Australia is secure and fair. Its offshore licence is legitimate, though it lacks the backing of local regulators. SSL encryption worked as advertised, my network checks confirmed safe payments, and game RTPs behaved as expected. Responsible gambling tools are available, though not as strict as they could be. Overall, I felt my funds and data were safe, and games were run fairly. King Billy Casino is licensed by Curaçao eGaming, one of the most common regulators for offshore casinos. I verified its licence number (8048/JAZ) via the regulator’s database, and it was valid at the time of review.
