Wounds that were beginning to heal at the Department of Foreign Affairs and Trade have been reopened.
An internal survey leaked to the ABC shows just 33 per cent of former AusAID staff feel part of the team compared to 70 per cent of their colleagues who have always been at DFAT.
The department absorbed AusAID in November and the culture clash has constantly boiled over into media reports.
Not least of which were claims a DFAT officer pretended to fire a machine gun into the massed AusAID ranks as they stood in the ground-floor foyer below.
The leaked report made public today says 21 per cent of ex-AusAID staff surveyed indicated they would leave the agency within the next two years, compared to 11 per cent of staff who were at DFAT before the integration, according to the ABC.
Meanwhile, 70 per cent of integrated DFAT staff said they were proud of working there, a decline from two years earlier when 85 per cent of DFAT staff and 90 per cent of AusAID staff expressed pride in their respective employers.
The proportion who would rate DFAT as a good place to work reduced to 57 per cent.
This was a fall from around 70 per cent in 2012.
Only the key findings of the survey were distributed to staff earlier this month, and many of the results are not disaggregated by former AusAID and DFAT staff.
A DFAT spokesman told the ABC staff probably had more certainty now than when the survey was done.
