Shane Warne's prizemoney allocation for Australia's World Cup win has been defended amid claims the banned leg spinner did not deserve it.

Warne is set to receive up to $15,000 from Australia's victory despite not bowling a ball in the tournament and being banned from cricket for one year for failing a drug test.

Warne was in South Africa for 11 days and will collect the cash through a pro-rata system adopted by the players for the 55-day tournament.

His allocation - believed to be between $10,000 and $15,000 - has come under fire from Australian cricketing great Neil Harvey and is likely to anger large sections of the public.

But Warne's manager and brother Jason said the banned star deserved his share of Australia's $3.36 million windfall.

"From my own point of view it's a tough one, but how far back do you go? He's already being punished enough as it is, but do you go back and make it retrospective?" Jason Warne said.

Jason Warne said his brother's input into Australia's victory could not be quantified.

But he said it was a "bit harsh" to strip Warne of his stake given his involvement in team planning and training and World Cup promotions.

"He is already missing out on income for the next 12 months and you've got to draw the line somewhere," Jason Warne said.

"The (anti-doping) committee drew the line in the sand when the suspension was started from February 10.
