- Qantas CEO Alan Joyce's mansion was hit with eggs and toilet paper, per Sky News Australia.
- Pictures show litter on the roof and garage door of the mansion the next day, per the report.
- The vandalism comes as the airline industry is struggling to handle the high travel demand.
The $19 million mansion owned by Qantas Airways' CEO was hit with eggs and toilet paper as the travel industry took a turn for the worse this summer, Sky News Australia reported at the time.
CCTV footage obtained by Sky News showed a person throwing several rolls of toilet papers and some eggs onto Alan Joyce's property, which is located in Mosman, a suburb of Sydney, Australia. The incident took place in the early hours of July 12.
The unidentified culprit then got into a dark-colored vehicle and drove off, Sky News reported.
Pictures were taken of the property the next day, showing toilet paper, eggs, and another unknown substance littered on the roof, per Sky News, which included the images in its report. One of the garage doors was also hit with a red substance, according to the report.
Sky News reported at the time that police were investigating the incident. However, they have so far failed to identify the vandal, Bloomberg reported on Wednesday.
"The case will remain closed unless further information is provided," the police said in a statement to Bloomberg.
Qantas and Joyce didn't immediately respond to Insider's request for comment made outside of normal Australian operating hours.
Sky News reported that Joyce and his partner Shane Lloyd purchased the mansion, built in 1908, for $19 million.
The vandalism incident came at a time when airlines, including Qantas, were grappling with a staffing shortage amid a very busy summer travel season.
Passengers who have flown with Qantas have reported various issues, including lost luggage, delays, and a 13-month-old baby who was booked onto a different flight from her parents.
Qantas recently asked its senior office staff to step in as full-time baggage handlers at airports for three months. The carrier told Insider that about 200 Qantas office employees have been helping out at airports since Easter.
