Society should reconsider whether politicians should further receive retirement benefits given some take up lucrative lobbying jobs, a director of the Centre for Public Integrity, barrister Geoffrey Watson, SC, said after it was reported that former prime ministers Paul Keating and Tony Abbott may be on the payroll of billionaire box king Anthony Pratt.

The Sydney Morning Herald and The Age reported on Monday that documents showed Mr Pratt, whose fortune from paper recycling and box-making is estimated at $23 billion, paid Mr Keating $25,000 a month and Mr Abbott $8000 a month for consultancy services.
