The search for missing Kallista man Zak continues a week after he was last seen in Kallista.
Local SES volunteers continue to assist police with the search, navigating tough terrain to locate the missing 22 year old – who has a medical condition.
Zak was last seen on Norton Road, Kallista, on the evening of 28 April.
Police believe Zak may have gone walking in the Sherbrooke Forest in the early morning of 29 April.
SES Lilydale Controller Shaun Caulfield said that concern has been growing as the days since Zak disappeared increased.
“We are hoping for the best outcome,” he said.
Temperatures have been cold overnights in the areas and Mr Caulfield said being out in the weather “would not have been pleasant”.
Posters have appeared throughout the hills appealing to the public for any news of the young man and police and family have concerns for Zak.
His disappearance is out of character and police stated he had a medical condition in their release to public on Eyewatch.
Zak is described as Caucasian in appearance, 170cm tall, of medium build with short blond/brown hair and possibly a moustache.
Around 50 SES volunteers per day from Emerald, Lilydale and Monash units have been assisting police with the forest based search.
Mr Caulfield said the terrain has been quite arduous and that the SES has been getting right down into the gullies and waterways.
“The search has been very thorough,” he said.
Zak was last seen wearing a grey jacket, mustard-coloured t-shirt, navy tracksuit pants and black shoes.
Anyone who sights Zak is urged to contact Belgrave Police Station on (03) 9754 6677 or call 000.
