A former British police sergeant has agreed to be sent back to England to face more than 20 allegations of sexually assaulting children.

The 76-year-old was arrested at his home on Queensland's Sunshine Coast on January 10 over allegations he abused a number of children between 1960 and 1974.

It's alleged most of the abuse occurred when he lived in Accrington, in Lancashire, in England's northwest.

Police say the man moved to Australia in 2002 after being made aware allegations had been made against him.

He appeared in Brisbane Magistrates Court on Friday for a brief hearing, at which he said he would not fight extradition proceedings instigated by police in East Lancashire.

The court was told he would remain in Brisbane's Arthur Gorrie Correctional Centre until the Australian attorney-general, Mark Dreyfus, issues a surrender warrant.

A spokesperson for Mr Dreyfus said that would happen "as soon as possible".

British authorities will then have 60 days to make their way to Australia to collect the accused.
