The Australian former drug smuggler executed in Indonesia will receive a final farewell today.

Ten days after Myuran Sukumaran was shot by a firing squad mourners will gather to say their goodbyes at a Sydney church.

The 1200 person capacity DaySpring church at Castle Hill is expected to be full, with overflow areas in place to accommodate a large crowd at the 34-year-old's funeral today.

Australian artist Ben Quilty, who forged a close friendship with Sukumaran as a mentor, will be among the speakers.

Fellow drug smuggler Andrew Chan was farewelled by thousands at a service in Sydney yesterday.
