Gibson, who joined the Tahs as an assistant to Michael Cheika in 2013 before taking over as head coach in 2015, had one year remaining on his contract.
Fined $1300 and suspended from driving for three months after pleading guilty to mid-range drink-driving, the Wallabies hooker this week was hit with a $5000 breach notice by Rugby Australia and banned for four matches.
"I'm proud to have served as head coach for that period, this is now a wonderful opportunity for someone to bring the next generation of young players through and really own that process for the next three or four years".
Whatever the case, Gibson's departure has put the icing on an unpalatable cake that was supposed to be a good-news Waratahs' season when they would take rugby back to the people of NSW.
Berne fills the attack coach role vacated by StephenLarkham 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. He will leave with a win rate of 48.3 per cent (28 wins from 64 games). Gibson recorded 10th and 12th-placed finishes in the following two years, before reaching the semifinals after topping the Australian conference in 2018.
Gibson said the Folau sacking had no bearing on his decision but admitted it had been "tiring". "The time taken away and invested in that was taken away from our focus on rugby".
But even more concerning is the fact that Wallabies playmaker Bernard Foley is rumoured to be heading to Japan, while fellow internationals Kurtley Beale, Adam Ashley-Cooper, Karmichael Hunt, Ned Hanigan, Rob Simmons and Tolu Latu are all also off contract after this year's World Cup.
NSW Rugby chief Andrew Hore said it was "hard to sum up the contribution Daryl has made".
"It's the work behind the scenes that you don't see that he'll be remembered for".
