Australian professional surfer Mitch Coleborn could be jailed in Canada after he allegedly exposed himself to a group of people near a school.

Coleborn, 23, from Queensland's Sunshine Coast, was on British Columbia's Vancouver Island for a surfing competition when the incident took place after a night of drinking.

Police say he is alleged to have exposed his genitals in a public place to a group that included several children.

He has been charged with committing an indecent act and if convicted could be sentenced to six months in jail.

In addition his name could be added to Canada's National Sex Offender Registry.

Coleborn has been ordered to stay in British Columbia until his court appearance on November 1.

He is not allowed within 100 metres of a park or school and he must abstain from consuming any alcohol or drugs.
