"Thanks for getting me on board," Brummer posted on Facebook. "I am looking forward to a future working high above Covid which is 'apparently' 'ravaging' Sydney."
But two days later, the New South Wales government paused all construction projects in greater Sydney for two weeks in an attempt to slow down a new surge of Covid cases and the lockdown was a devastating blow for Brummer.
"He was really excited and really grateful about the job," his grieving employer told the Daily Mail.
"The lockdown took the wind out of his sails."
Brummer appeared on Home and Away as Shane Parrish from 1992 to 1996, winning a Silver Logie award for the most popular actor in both 1995 and 1996.
He then went on to appear in several TV dramas, including Rescue Special Ops, Winners and Losers, the Underbelly series, and Neighbours in 2011 and 2012 as the character Troy Miller.
The actor worked as a window cleaner between roles and was running his own business.
A Seven spokesperson told news.com.au, "Home and Away and Channel 7 are deeply saddened to hear of Dieter Brummer's passing.
"Dieter was a much-loved Home and Away cast member and celebrated by Australian and international audiences for his award-winning portrayal of Shane Parrish. We send our sincere condolences to Dieter's family and friends during this very difficult time."
