A convicted paedophile on parole in WA's South West has been discovered living less than 100m away from a public playground in the same town where he sexually abused a young boy.

Busselton driving instructor Peter Wallace Hill walked free this month, after serving just two years of his four-year jail term for the sexual abuse of a 13-year-old.

Hill was jailed in April 2018 over a series of child sex offences he committed with his lover, David Lindner, in the Busselton region since 2017.

Lindner had been assaulting the boy for months when he invited Hill to take part.
