I have an Australian passport and have stayed 90 days in Bulgaria but have now left. I first entered the country on September 16th 2018.
My question is am I able to re-enter the country 180 days after my initial entry date (which would mean I can go back in March) for another 90 days without needing to apply for a visa? Or now that the 90 days have been used to re-enter will I need a visa?
