From Australian TV Week:

 

- In other Neighbours news, songbird Delta Goodrem could be poised to make a return to the show that helped make her a star. The word is that Delta is in negotiations to return to sing at Charlie's Bar, but there's no word yet on whether she'll play herself or her one-time character, Nina, on the show.

 

I soooooooooo hope it is true!!!!!

Ooh I hope that's true!!!

thanks!! hope its true. one episode would even be great

thanks!! hope its true. one episode would even be great

how exciting - hope this is true

Yes please :)

thats so cool...but her coming back to the show as "Delta" would be kinda stupid...

She should only come back as Nina cuz I agree that would be totally stupid and confusing if she was Delta. Even though Nina basically is Delta :P!

Are any of the characters originally involved with Nina still in it?

susan, harold, carl, steph, boyd, the oldies mainly. none that are or were really involved

Lou i still there and she has a connection with him as Nina's mum was once married to him and i think Lou thinks of Nina as one of his own anyway. And since Lollie has left, it might perk him up a bit

They are going to have a regular thing with artists performing in Charlies (the new Scarlet Bar) so it would be perfectly ok for Nina to be booked to perform there without having connections really to anyone left in Neighbours. Plus she has the Lou connection and also Steph is Jack's sister, and Nina and Jack are together!
