UPDATE: Max and Penny Stickland attended Mukinbudin Police Station this morning after hearing reports from police.
Wongan Hills Police are urgently seeking information regarding the whereabouts of 74 year-old pair Max Vernon Stickland and Penelope Dorinda Stickland.
They are believed to be driving a 2014 silver Holden Colorado station sedan, registration 1ELV601, towing a 22 foot caravan with an unknown Victorian registration plate.
It is also believed that they have been camping in and around the Burakin/Mollerin areas.
Max is described as fair skinned, with a solid build, approximately 178cms tall and grey hair.
Penelope is described as fair skinned, thin build and shoulder length grey hair.
Concerns are held for their welfare as they have not contacted their family in the last four weeks, which is out of character.
Anyone who sees Max and Penelope or their car and caravan are asked to call police immediately on 131 444.
