Debra Lawrence, who played Pip on Home And Away, commented, "@kateritchieofficial It was so lovely to see everyone and to experience the love for Dieter … what a family we are."
The post suggests that there was some sort of private memorial held for Brummer over the weekend.
Richie is among many other Australian stars who paid their respects to the Logie-winner actor, who was confirmed dead when police found him in his home in Glenhaven last month.
NSW Police said officers from The Hills Police Area Command responded to reports of a concern for welfare at a home on Glenhaven Road.
"The body of a man was located inside the home," it said in a statement. "His death is not believed to be suspicious."
His family issued a public statement, remembering him as a "handsome, talented, funny, complicated and beloved" man.
"On behalf of my family, I post this today with a heavy heart," the statement read.
"He has left a massive hole in our lives and our world will never be the same.
"Our thoughts go out to all of you who knew him, loved him, or worked with him over the years.
"We appreciate you respecting our privacy at this terrible time."
Brummer was best known for his role in Summer Bay between 1992-1996 where he featured in more than 500 episodes.
In 1995 and 1996, he won the silver Logie for Most Popular Actor for his role in Home And Away and was nominated for the gold in 1996.
Throughout his career, he continued to feature in a string of TV shows, including Medivac, the Underbelly series, Winners and Losers and even joined the Neighbours cast in 2011.
