The former tennis champion declared his win over Labor's star candidate Kristina Keneally a "renaissance" of Mr Turnbull's leadership before an adoring sea of blue on Saturday night.
Mr Alexander, who likened the thrill of winning to being selected to represent Australia in tennis, said he believed the bitter by-election, marred by stunts and dirty tricks, had brought his party together.
"This is a renaissance of your leadership," a proud John Alexander said to Mr Turnbull.
