NeurIPS Registration - How to get one if all tickers are sold out in Sydney? [D]

Hi, I am a solo independent UG author for a NeurIPS WS paper (GlobalSouthAI). Now, how to get a registration ticket. Will they give us a ticket to buy or manually buy from the Neurips website (but Sydney tickets are sold out)? Any suggestion? I am from India, and going to Paris/Atlanta is not possible. First time, thanks!!
