Greater Western Sydney players and officials have not been in their home state for weeks since the New South Wales COVID-19 outbreak began.
The club confirmed Hill will head home and will have to await approval to re-join teammates, who are expecting to have their families granted arrival to transition hubs.
“Bobby returned home to Sydney with our full support," Giants football boss Jason McCartney said.
“As we know, the two Sydney clubs have faced plenty of challenges over the past few weeks and we appreciate the sacrifices our players and staff have made.
“Family comes first so Bobby will return home now with our full support and if the option becomes available for him to re-join the group then we’ll welcome him back as soon as we can.”
Hill would likely join awaiting families in the transitional hub, meaning a 14-day isolation period would be required before being available for selection.
