Murray Olds: Australian correspondent on the ongoing police search for missing Sydney couple - Heather du Plessis-Allan Drive

New South Wales police are still searching for missing Sydney couple, Jesse Baird and Luke Davies.

They've accused 28-year-old constable, Beau Lamarre-Condon, of murdering them in Baird's home.

Detectives are again scouring a rural property visited by Lamarre-Condon, after finding nothing yesterday.

Australian correspondent Murray Olds says the accused constable is refusing to co-operate with the ongoing search.
