Dieter Brummer is returning to Neighbours to reprise his character Troy Miller, the tormented ex boyfriend of Sonya Mitchell and Callum Jones’s biological father. 

Troy fled Erinsborough after roughing up street stalwart Harold Bishop, as well as taking on Toadie and terrorising Sonya and Callum, and the residents of Ramsay Street thought they had seen the last of him.

Former Home and Away star Dieter, who is based in Sydney, returned to the Neighbours set this week, filming scenes with Eve Morey (Sonya Mitchell), Ryan Moloney (Toadie), Gemma Pranita (Jade Mitchell) and Morgan Baker (Callum Jones). 

“I really enjoy being in Melbourne and while my character doesn’t receive much of a welcome, the cast made me feel at home,” joked Dieter. “I resumed my place in the Green Room like I had never left.” 

Sources say that Dieter’s storyline, which screens in the UK in June, will be one of the most dramatic for 2012. 

Simmone Jade Mackinnon is also joining the Australian soap for a three-week guest role as Paul Robinson’s super-glam publicist Zoe Alexander.

Simmone, who starred opposite David Hasselhoff in the Baywatch spin-off Baywatch Hawaii, started filming her scenes this week.

Her character is described as a tough cookie who’s up for the challenge of making over one of Ramsay Street’s bad boys.
