Elder sister Vaseva Waqavatu confirmed this yesterday.
Speaking from Taveuni, she said their parents were aware of Radradra's sudden switch because of personal issues.
Waqavatu said her brother flew into the country on Saturday after he was granted permission to visit his family.
"Semi had discussed his move with my parents and we are supporting him 100 per cent," the Year 2 schoolteacher said.
Waqavatu said Radradra would return to Australia for the Eels match against Cronulla on July 2.
She added he would be in Taveuni later this week to spend some time with his parents and sibblings.
The Sydney Morning Herald reported that it was understood the Eels were willing to consider allowing him to play in France from August until next April on the condition that he will return to the Eels for the next three seasons.
It was also reported that the 24-year-old's departure to Fiji last weekend, had been compared to Sonny Bill Williams sensationally walking out on Canterbury in 2008 to play rugby union for Toulon in France.
A statement issued on Saturday night by the Parramatta Eels stated that they expected Radradra to return before the Cronulla match.
"The Parramatta Eels can confirm that Semi Radradra has been granted permission to return to Fiji for a short family visit during the bye round," the statement said.
"He is expected to return to Sydney in time to prepare for the club's next NRL game against Cronulla.
"Semi Radradra is contracted to play for Parramatta Eels until the end of the 2017 season, and has given no indication that the contract will not be honoured."
