An elderly Perth couple has been left heartbroken after thieves allegedly targeted their Gosnells home, stealing a safe containing irreplaceable personal belongings collected over decades.

The burglary occurred while the homeowners, both in their 80s, were away from the property. Upon returning home, they discovered intruders had forced entry and made off with a heavy safe that held much more than valuables.

According to family members, the stolen safe contained important documents, family photographs, jewellery and deeply sentimental items that represented a lifetime of memories. The emotional toll of the crime has been particularly devastating, with loved ones describing the elderly couple as "absolutely shattered" by the ordeal.

Speaking to 9News, the couple's daughter explained that while some of the contents had financial value, many of the stolen possessions could never be replaced.

"It's not about the money," she said. "It's the memories that have been taken away from them."

Police believe the offenders deliberately targeted the residence, managing to remove the safe despite its size and weight. Investigators are now appealing to the public for information that could assist in identifying those responsible.

Detectives are urging residents in the Gosnells area to review any home security footage or dashcam recordings that may have captured suspicious activity around the time of the burglary. Authorities are also asking scrap metal dealers, pawn shops and second-hand traders to remain vigilant for any items that may match the description of the stolen property.

The incident has sparked renewed concern about crimes targeting older Australians, particularly those living independently. Community advocates say elderly residents often feel especially vulnerable following break-ins, with the emotional impact frequently lasting long after the financial losses have been addressed.

Neighbours have rallied around the couple, offering support and helping spread awareness about the missing belongings in the hope that some of the sentimental items can be recovered.

WA Police continue to investigate the circumstances surrounding the burglary and have encouraged anyone with relevant information to contact Crime Stoppers on 1800 333 000.

The case serves as a sobering reminder of how property crimes can profoundly affect victims. For this Gosnells couple, the loss extends far beyond the contents of a safe. Among the missing items were pieces of family history that had been carefully preserved over generations.

As police work to track down those responsible, the family remains hopeful that some of the cherished keepsakes may eventually be returned.

Anyone with information about the incident, or who may have seen suspicious behaviour in the area, is urged to come forward.

The investigation remains ongoing.
