The man set to head the upcoming Royal Commission into child sex abuse has been appointed a judge of appeal in NSW.
NSW Attorney-General Greg Smith said Justice McClellan's new role capped an eventful start to the year after he was last month appointed chair of the Royal Commission into institutional responses to child sex abuse.
"In practical terms, Justice McClellan will not sit as a Judge of Appeal until he has completed his duties at the royal commission," Mr Smith said in a statement.
Mr Smith also announced two other appointments on Wednesday.
Justice Hoeben's appointment will begin on February 22.
Justice Emmett will begin serving on the bench of the Supreme Court on March 7.
