Uber, Doordash, Woolworths, Coles, major transport operators, industry associations and the Transport Workers Union met with Employment Minister Tony Burke on Monday, ahead of the federal government's jobs and skills summit.
The organisations agreed to back a set of proposed reforms to lift standards for transport workers and ensure a safe, sustainable and fair road transport industry.
The push for industry reform comes after more than 50 transport workers were killed at work in the last year.
Hundreds of truck drivers, industry leaders and gig workers descended on the nation's capital in July to call for safety reforms.
The agreed principles call for the government to establish an independent body with powers to set work standards, promote best practice in the supply and contract chain industry and effectively resolve disputes.
The body would also give transport workers access to a collective voice and would convene regularly to provide advice and recommendations to the government.
Australia's leading supermarkets, global gig companies, major transport operators, employer associations and workers were aligned on the need for reform, TWU national secretary Michael Kaine said.
"This is a powerful blueprint for reform backed by every section of the industry," he said in a statement.
"An industry coalition calling in unity for our system to be modernised ... is the strongest endorsement the federal government can receive to act quickly and with the backing of industry to get life-saving reform off the ground."
