Investigations have switched to the Tamworth and Armidale areas as Strike Force Wehl detectives attached to Tuggerah Lakes Local Area Command investigate the disappearance of 23-year-old Leisl Smith.

Ms Smith was last seen leaving her Wallarah home in her Honda Accord about 1pm on Sunday, August 19.

Family members who became concerned for Ms Smith after she failed to return home reported her missing to Tuggerah Lakes Police.

Local police immediately began their inquiries into the circumstances surrounding her disappearance.

Ms Smith’s car was found abandoned at the Tuggerah Railway Station car park a week after she went missing. The vehicle was seized for forensic examination.

Investigations have also revealed Ms Smith has not used her mobile phone and her bank accounts have not been accessed.

It’s thought she might have travelled to the Hunter or Tamworth/ Armidale area.

Strike force detectives are again turning to the public for assistance as they continue their inquiries.

They’re treating her disappearance as suspicious and have serious concerns for her wellbeing.

“Leisl’s disappearance is very much out of character, and police and her loved ones are extremely concerned for her welfare,” Tuggerah Lakes Local Area Command crime manager Detective Inspector Dave Waddell said.

“Leisl is an animal lover and her horse gave birth to a foal in late August.

“She was very excited about the impending birth and the fact that she missed the event is worrying.

“We are keen to hear from anyone who might have seen or heard from Leisl in the past few months.

“In particular, if anyone in the Hunter or Tamworth/Armidale areas has seen Leisl or a woman matching her description, we’d ask them to come forward.”

Anyone with information about Leisl Smith’s disappearance or whereabouts can contact Tuggerah Lakes Detectives or Crime Stoppers on 1800 333 000.
