The Centennial finance offer was superior to the Investec Loan Facility originally offered, Austral said. Centennial is the lead lender under a Syndicated Facilities Agreement, with NM Rothschild & Sons providing guarantee and stockpile facilities.
Austral has now been able to repay a bridge loan from ANZ and a loan from the Noble Group.
Austral has also settled a dispute with contractor Roche Mining regarding contract variations from development work at Tahmoor. Roche has finished up at the colliery with Austral taking over the work.
Centennial made a $300 million scrip bid for Austral in February and now holds 69% of the smaller outfit.
Shares in Austral slipped 3.7% Monday to $1.35 with Centennial also sliding 2.4% to $4.90.
