Hi, I am a father of twin girls. I pay child support but my ex took off with them and I have not seen them in over 2 years. I have tried and tried again to see them or contact them with no luck. I have now received a application letter for myself to sign for my girls to get a Australian passport to leave the country. Please how do I stop this? She won't let me see my kids, yet she wants to take them out of the country. I am not ok with them leaving the country. I don't even know where she's planning on going or who my children will be with.
