Paul Barry, an award-winning journalist, defended his controversial tell-all and said Warne probably needs scandals to get motivated.
''I think he almost needs, or likes, the notoriety and he likes the exposure,'' Barry the Nine Network's Today.
''You see time and again when he gets into some scandal or other that he comes out and plays better than he ever has done and I think it goads him to greater heights.
''It's as if he needs to establish that we need him, and that we'll still love him,'' Barry buttressed his point.
His comments in the unauthorised biography of the leggie raised hackles with some quarters dubbing it sloppy journalism.
But majority of the people, however, seems on Barry's side and according to a new poll, 69 per cent of the Australians don't believe Warne is a great Australian.
The ninemsn news poll received just under 50,000 votes and comes days after revelation in the book.
Barry, meanwhile, was undaunted by threats by Warne and his estranged wife Simone, to sue him over some of the claims.
''Simone says she'll sue and she says Shane will sue as well. I'm not quite sure what Shane's going to sue for as the suggestion he's been unfaithful is hardly new,'' Barry said.
According to ''Spun Out'', Warne has had sex with at least 1000 women and the leggie had his first affair barely four months after his tumultuous marriage to estranged wife Simone in 1995.
Barry also claims that the Aussies adhere to a code of silence which encourages promiscuity by Warne and other team members and apart from their ''coffins'', carrying gears, they ensure they never run short of condoms.
Barry quotes one of Warne's team-mates described his marriage to Simone as a wedding between a naive ''suburban girl'' and an accidental hero.
''There's no rocket science going on. He's a spin bowler, she was a promotions model. They have both got blonde hair... If she hadn't married she'd still be putting on a red lycra suit when According to his friends, Warne loves to ''collect'' women, especially the blondes.
