More than 800 friends and family turned out to farewell the 48-year-old midwife and mother of two, who died in a car crash 400m from the front gate of her Woodside home last Wednesday.
Tributes flowed from family members, colleagues and friends, who recalled a passionate, determined and dedicated woman, who was "unlike anyone else".
All agreed Mrs Hall was a larger than life personality and a big-hearted woman, who lived for her family and work.
Her love of shopping, "bling", well-painted nails and her determination, disregard for rules, compassion and sense of humour were often mentioned.
"Gayle said what she thought and she didn't really care who heard it, but she also made us laugh, and we will remember those times with great affection," Queen Mary Clinic colleague Caroline Folland said.
Others spoke of her love of a social occasion.
"I think she would have liked this," radio personality Damian Newell said of the large gathering at the funeral service.
Mrs Hall had been his station's most frequent contributor with her regular texts and calls.
Mrs Hall's two children, Adam (22) and Mikaeyla (18), were the last to pay tribute to their mother.
Adam, who won a skiing gold medal at the Paralympic Winter Games in Canada last month, broke into an occasional sob as he spoke of how he was still stunned at his mother's death.
"Last Wednesday was one of the toughest days I've had to go through.
"Mum was the best mum anyone could ever have. She was there from day one supporting me, the family, everyone.
"She was always so passionate. No matter what she wanted, she would do it, she'd never give up.
"It's just a shock and I can't believe it ... it's just so hard."
Mikaeyla Hall said life was going to be tough without a mother who was always there for her.
"I wish we had a second chance. I want you back."
Both Adam and Mikaeyla said the last month, which the family, including their father Lindsay, had spent in Canada and the United States for the Games, was the best time of their lives, and they would never forget it.
When the service ended, the family carried Mrs Hall to a waiting hearse past a guard of honour formed by her midwifery colleagues.
