Alisha, who did not want her surname published, left her Winter Valley home early to start work at 7am on Monday. Returning home around 4pm, the young nurse discovered that the home she shares with three friends had been torn apart.

The first thing she noticed upon entering the house was kitchen cupboards flung open and items strewn over the floor.

Continuing through the house, she was shocked to see that a burglar/burglars had searched every single room in the four-bedroom house for items of value.

"Everything was upside down, contents everywhere and everything of value taken," the 24-year-old said.

At least $15,000 worth of valuables were stolen - including computers, printers, a Fisher and Paykel clothes dryer, a bar fridge, passport, jewellery, cash and clothes.

"They even took my bedding - sheets and my doona - which was really strange," Alisha said.

They even took the time to unwrap some of the Christmas presents which had been placed under the Christmas tree, taking off with those which took their fancy.

"I feel violated and sick to know that somebody has been in my house and in my room going through my belongings," Alisha said, adding she now felt uneasy being at home.

Alisha feels the burglary has ruined not only her Christmas, but also her housemates' - three women she met at university.

She had tried to be organised by completing all of her Christmas shopping early this year and is upset by the fact many of these gifts were taken.

"It's Christmas time and it's supposed to be a happy time but you have gone and ruined it for four friends and their families," she said of whoever is responsible.

"I hope you're happy with yourselves and have a s***** Christmas."

She encouraged anyone who sees any of the stolen items being listed online to report it to police.

Crime Scene investigators have been to the house to collect evidence while detectives from the Divisional Response Unit are investigating the burglary.

The burglar/ burglars are believed to have gained access to the home through the garage roller door, which Alisha left open in her rush to get to work. She said the interior door to the house was locked, however.

"The invasion of privacy and feeling of vulnerability when an intruder enters a family's home can't be measured; we take this type of offending very seriously and are committed to holding offenders to account," a spokesperson said.

They said that opportunistic thieves all too often entered homes through open or unlocked doors and windows so reminded everybody to take simple steps to reduce the risk of becoming a victim of burglary.

These steps include installing good quality locks on doors and windows and ensuring they are locked.

With rear and side doors the most common entry points for burglars, it is also important to ensure garage doors and doors providing internal access to the house are locked too. An alarm or CCTV system can also be installed for further security.

Police urge the community to report any suspicious behaviour immediately via Triple Zero (000) or after the fact by calling Crime Stoppers on 1800 333 000.
