"I think during the year I had a change of heart around exactly where the team is and where the list is at", Gibson said of the about-face on his contract extension.
Outgoing Waratahs coach Daryl Gibson says it's time for someone else to take the squad through their next stage of development.
Super Rugby semi-finalists and Australian conference winners a year ago, the Waratahs finished 12th on the ladder in 2019 after winning only three of their last eight games without the suspended and subsequently sacked Folau. "We've got this wonderful, young, vibrant talent coming through our system; we've got some absolute gold nuggets that are going to filter through our system in next three to four years.it's time for a new coach to take them on that journey".
Well-travelled Berne enjoyed spells as a player with Bath, the Waratahs, and Calvisano as well as Leinster before he began his coaching career as the province's "A" coach in 2015.
Shaun Berne has joined the Wallabies coaching staff to give head coach Michael Cheika a full complement of assistants in the run-up to this year's World Cup, the team announced on Friday.
"Obviously Israel's had an incredible impact not only off the field but also on the field", he said.
"It's been a challenging period leading people through that", he admitted.
Berne fills the attack coach role vacated by Stephen Larkham earlier this year, after the former Wallabies fly-half and Cheika could not overcome "differences of opinion" on how Australia's game plan and attacking framework. "The time taken away and invested in that was taken away from our focus on rugby".
Former All Black Gibson was contracted through till the end of the 2020 season.
Gibson was an assistant coach at the Crusaders, far and away Super Rugby's most successful franchise, before joining Cheika at the Waratahs in 2013. He was instrumental in the Waratahs' 2014 title-winning campaign.
