Trauma specialist Dr Warwick Middleton said the psychological damage caused by child sexual abuse meant victims were usually not ready to address the abuse for many years.

Doctor of Law Professor Ben Mathews said this delay meant most victims were barred forever from obtaining compensation through the courts.

"This is an intolerable situation," he said.

"This is fundamentally a question of access to justice and it is completely unfair and unjust that in a mature liberal democracy survivors of child sexual abuse should be barred from getting access to the civil legal system."

Prof Matthews will be a key speaker at a forum on the matter at Queensland's Parliament House tonight.

He said the repeal of time limits had not led to a flood of claims in other countries where the laws had been repealed because they were costly, lengthy and emotionally traumatic.

The Royal Commission into Institutional Responses to Child Sexual Abuse recommended in September the Statute of Limitations should be repealed immediately by all Australian states and territories and should take effect retrospectively.

Victoria repealed time limits last year and NSW repealed the legislation in March this year, both retrospectively.

Bravehearts founder Hetty Johnston said it was time Queensland followed suit to repeal the legislation.
