The Abbott government's cull of public service jobs is proving to be a cash bonanza for some top bureaucrats in Canberra who are scoring golden handshakes worth hundreds of thousands of dollars.

Three assistant departmental secretaries, a first assistant secretary and two other high-ranking executives were among the latest round of 128 redundancies to be officially notified, taking generous ''incentive to retire'' packages on their annual salaries of up to $270,000.

The high flyers are among 74 of the bureaucracy's elite "senior executive service" to leave their departments and agencies since July 2013.

Most of them will then be able to access some of Australia's most generous super provisions, while seeking work elsewhere.
