The Department of Foreign Affairs and Trade spent an estimated $215,000 or more sending nearly two dozen senior bureaucrats from Canberra to Paris to attend an inhouse talkfest about ways to save money.

Fairfax Media can reveal the two day junket in September included business class return travel for all 23 DFAT officers.

They included John Philp, Australia's former ambassador to Afghanistan and current first assistant secretary of the consular and crisis management division and John Fisher, first assistant secretary of DFAT's corporate management division.

But the entourage, which was hosted for the two day conference by Australia's ambassador to France, Stephen Brady, included a departmental psychologist, a conduct and ethics manager, and a health and safety officer, according to a list of attendees obtained by Fairfax Media.
