7.56am: CONCERNS are held for the welfare of a couple in their 70s who have not contacted their family for four weeks.
Wongan Hills Police are urgently seeking information regarding the whereabouts of 74-year-olds Max Vernon and Penelope Dorinda Stickland.
They are believed to be driving a 2014 silver Holden Colorado station sedan, with the registration 1ELV601 and towing a 22-foot caravan (similar to the one pictured below) with an unknown Victorian registration plate.
It is also believed they have been camping in and around the Burakin/Mollerin areas.
Mr Stickland is described as being fair skinned and about 178cm tall, with a solid build and grey hair.
Mrs Stickland is described as also being fair skinned, with a thin build and shoulder-length grey hair.
They have not contacted their family in the last four weeks, which is out of character.
Anyone who sees the couple or their car and caravan are asked to call police immediately on 131 444.
