He was barefoot, and left without his wallet or phone. Family and friends, too distraught to speak after their four-week search for the 36-year-old ended, were still coming to terms with the loss.
Robinson's silver Subaru wagon, which featured in repeated police appeals for his whereabouts, appeared to have left the Marieba Rd in semi-urban Kenthurst, clipping the top of a cliff and plunging down a rock face.
The grisly scene was discovered by electrical workers just after midday, about 13km from where he lived in Crestview Avenue in Kellyville.
It came just weeks after Robinson's sister, Monique Brennan, made a desperate public appeal for his return, revealing how they had scoured the local bushwalks and waterfalls her brother loved so much.
Last night, the heartbreaking truth prompted a touching tribute.
"It's with a heavy heart that we can confirm that Chad's body was found this afternoon," a statement on the Let's Find Chad Facebook page said.
"There are no words for our whole family's loss and especially his two beautiful kids.
"Thank you, every one of you, for your support the last few weeks. Brother, you were the world to all of us. I can't imagine life without you, but you are free, fly high my beautiful brother."

Brennan, took to Facebook at the end of November calling for public assistance in finding Robinson.
Some friends knew of Robinson's struggle, but others said they never saw the signs. His beloved teenage children, Kiara and Cooper, along with sister Monique, brothers Tim and Scott, and partner Rani Morris, will forever be left wondering.
A distraught Morris yesterday visited the wreckage.
Like many players, Robinson's transition into life after football had its challenges, once he hung up the boots in 2009.
After growing up living rugby league in Sydney's northwest, Robinson played 159 NRL games across nine years at the Eels and Roosters, before a final season with Harlequins in the UK Super League.
Former team-mate Craig Fitzgibbon described the rugged back-rower as "the best forward at the Roosters" in 2003.
His split from his wife hit Robinson hard. Mates tried to lift his spirits by bringing him in as part of the Parramatta Old Boys group, where former players would come together.
It seemed to help, but, as a lot of things with Robinson, they never really knew.
Ultimately, it wasn't enough. As a friend of Robinson's said last night, he was an "all or nothing" bloke.
New Eels chief executive Bernie Gurr said the club was "devastated".
