The 24 year-old is actually signed on with the Eels until the end of 2017. Toulon also has Wallabies Drew Mitchell, Matt Giteau, James O'Connor and Liam Gill on its books.
Toulon won the European Champions Cup three straight years until 2015 and are rebuilding under Australian coach Mike Ford.
Radradra left for his native Fiji late last week with the Eels' permission to visit his father, who is ill with pulmonary tuberculosis.
He was due in Parramatta Local Court on Monday to answer three charges of domestic violence brought by his former partner Perina Ting, the magistrate was not satisfied with Radradra's absence, citing the nature of his father's illness as ongoing.
Radradra's arrest warrant will be held over until Thursday, offering the Kangaroos winger opportunity to explain his non-appearance.
The latest twist in his future drew criticism on social media from leading NRL commentator Andrew Voss, who tweeted: "I doubt there will be any need to send an invite to Semi Radradra for any future Kangaroos reunions. Zero integrity."
