PREMIER Anna Bligh is standing by her decision not to give a convicted rapist a Queensland Disaster Heroes' award.

Bob Riddler, who was convicted of raping a sex worker on the Gold Coast in 1997, spent 12 years in jail before being released last September. He is on a five-year supervision order.

When the floods hit Ipswich in January, Mr Riddler volunteered at Shiloh Christian Church in Goodna, using his van to transport food and furniture to flood victims.

He worked 14-hour days, seven days a week, wherever help was needed.

In early March, he was told by Corrective Services to stop volunteering. A request by the church's pastor to allow Mr Riddler to resume volunteering was refused.
