There is. I have a group on whatsapp with members from all over the world . We usually talk in English there. If you want you can join us.

Hi Verónica! Thanks a lot! Thanks a bunch! Thanks bunches! Thanks a million! Thanks a ton! Appreciate it! Much appreciated! I owe you one! Ta! (antiquated) A big thanks! You're the best!

There are some different way to say "Thank you", for example you can say 1) I appreciate that 2) Cheers 3) You're a life-saver 4) You're a star 5) I don't know what I'd do without you

I say "cheers" a lot as an informal way of saying thank you. "Thanks" is perhaps more formal than cheers, but less formal than thank you, if you want a scale. Very informal could be "nice one".

"Cheers" and "Ta" are Australian favourites! ;)
