Prime Ministers Avenue, Bronze busts collection in Ballarat Botanical Gardens, Australia.

Prime Ministers Avenue is a collection of bronze busts depicting Australian prime ministers mounted on granite pedestals along a tree-lined path in the gardens. The sculptures are spaced throughout the avenue and represent different periods of Australian political leadership.

The collection began in 1939 when Richard Crouch made a donation to establish it, with the first six busts unveiled in 1940. Additional sculptures were added over the decades to honor Australian leaders from different time periods.

Each bust stands in order of first term in office, beginning with Edmund Barton, and every prime minister is included regardless of time served. Sculptors worked from photographs or live sittings; Ken Palmer modelled Ben Chifley's bust in 1946 after the prime minister agreed to sit for him. John Howard disliked the size of his bust's lower lip, Paul Keating its weak chin and pointed nose, while Julia Gillard was pleased with hers.

The busts line the Horse Chestnut Walk, running from the begonia house to the southern end of the Ballarat Botanical Gardens. They stand in order of each prime minister's first term, beginning with Edmund Barton. The avenue is outdoors and free to visit; the level path is easy to walk.

In January 1944 the busts of Andrew Fisher and W. M. Hughes were taken from their pedestals, the first interference since the Avenue began. Both were found undamaged the next month: Fisher's beside the George V statue on Sturt Street, Hughes' at the Ballarat Soldiers' Convalescent Depot. The theft was put down to a lark.
