Catfished and threatened to send out explicit content if I don’t pay them - ADVICE PLS AUSTRALIA

I recently got a friend request on instagram from a girl who said she was just going through mutuals and looking to make some friends.

Told me she moved to Perth and lived with her auntie, we spoke for a couple hours on and off and after a while she asked for “help showering”, stupidly enough my boy brain gave in and agreed. So we swapped a couple photos and she then asked if I wanted to talk on discord, so I made an account and added them as a friend.

As soon as I added them they bombarded me with screenshots of all images I had sent (some explicit), screenshots of my friends list and even a screenshot of them sitting in a personal chat with my partner threatening to send out all of my information if I do not lay them money.

I’ve since blocked them on instagram, I’ve reported their discord / threats to my state’s cybersecurity dept, as well as given their iMessage email.

—should I just ignore the messages and hope they lose interest? I’ve read this is a good way to do it but obviously the threat of my info being sent out is still there

—I’ve stated I don’t have the money to pay them right now and “extended” it by a couple days to buy time a guess lol

•what can anyone recommend please - I’m stressed out•
