As environment minister, Richardson brokered key environmental deals, blocking Tasmania's Wesley Vale pulp mill and saving the Daintree rainforest. His skill as a negotiator proved crucial in securing an alliance with the Australian Democrats and early Green movements during the 1990 election.
However, his career was often marked by controversy. After a falling-out with Hawke, he backed Paul Keating's leadership challenge and later served as transport, communications and health minister. His close friendship with media mogul Kerry Packer earned him the nickname "the Minister for Channel Nine."
Richardson's ministerial career ended amid scandal - first over his alleged role in a migration scheme known as the Marshall Islands affair, then after further allegations linked to other political controversies. He resigned from parliament at 45, citing ill health.
Outside politics, Richardson built a second career as a media commentator, corporate negotiator and broadcaster. He became a fixture on Sky News alongside Alan Jones and contributed a regular newspaper column.
Despite declining health, Richardson remained active in public life - often outspoken, sometimes divisive, but always influential.
