The Western Sydney local joined the squad in December 2014 as an injury replacement player for Brendon Santalab and impressed before succumbing to injury himself.
The central midfielder played four A-League matches in his initial spell with the Wanderers as well as featuring in the FIFA Club World Cup against African Champions ES Setif.
After stints at Le Mans (France), Real Mallorca (Spain) and Blacktown City (NPL), his apperance for the Wanderers was his first taste of A-League action.
Baccus grew up in Blacktown after his family moved to Australia at a young age from his native country South Africa and the 23 year-old is honoured to continue his link with Western Sydney.
“I’m proud and excited to have signed an extended contract with the Wanderers, especially as I’m a Blacktown boy – representing my region is a dream come true” said Baccus.
“My time with the club during my short-term contract was one of the best experiences of my career so far and I’m delighted to have made that permanent.
“Popa has rejuvenated my career; he made me realise a lot of things and I look forward to getting over my injury so I can continue working hard to achieve big things with the Wanderers."
Baccus’ brother Keanu also plays for the club in the National Youth League.
