Reports emerged earlier this month that Pell had been moved from the Assessment Prison to a high security facility in regional Victoria after the drone was spotted near a visitors' garden.

Pell had been held at the prison for almost a year, after his 2018 conviction for sexually assaulting two teenage choirboys at Melbourne's St Patrick's Cathedral in the mid-1990s.

It had been speculated that the drone may have been used to try and get pictures of Pell, which could be worth a significant sum.
