The actress, who announced her decision to leave earlier this month, bowed out from the role of Summer Hoyland this week after three years in the part.
Lucas told fans on Twitter today (September 21): "Have said goodbye to my friend Summer. Now preparing to board a plane to a wonderful place tomorrow. I'm excited!!!"
Meanwhile, Lucas's former co-star Gemma Pranita - who recently left the role of Jade Mitchell - tweeted: "And that's a wrap for the beautiful @jordy3392. Sending her love as she bids farewell to Summer Hoyland."
Neighbours bosses have promised that the build-up to Summer's exit will involve "a romance that will test her moral compass".
Early reports have suggested that Summer's new man will be older guy Bradley Fox (Aaron Jeffery), the tough new deputy editor at the Erinsborough News, who is already on screen in Australia.
Lucas joined Neighbours in late 2009 after show chiefs decided to recast the role of Summer. Marisa Siketa had previously played the part on and off between 2002 and 2007.
