Bobby Burns will join Australian side Newcastle Jets on loan, subject to international clearance and visa approval.
The 19-year-old full-back moves to the A-League outfit until June 2020.
Northern Ireland U21 cap Bobby moved to Hearts in the summer of 2018 from Northern Irish side Glenavon.
Following a loan spell at Livingston, he went on to make 10 top team appearances for the Jambos and scored his first goal in last season’s top six encounter at Aberdeen.
The Jets are managed by Edinburgh-born head coach Eddie Merrick. They reached the quarter-finals of the FFA Cup, losing 1-0 to Adelaide United, and kick off the A-League season next month against Central Coast Mariners.
