A Melbourne woman could face a stint behind bars after using a homemade explosive device to set fire to a toilet inside the 2024 Land Forces expo.

Malith Shamera Fernando, 25, of Blackburn faced Melbourne Magistrates’ Court on Thursday, where it was revealed she had visited the Melbourne Convention and Exhibition Centre on the first day of the defence exhibition to scope out the facility before returning the following day to plant an explosive device on September 12, 2024. Fernando has pleaded guilty to all charges.

The court heard that Fernando, an engineer, attended the exhibition centre with a legitimate ticket and visited the area for 40 minutes. The following day she arrived at 12.47pm, scanned her ticket and walked into the male toilets.

Shortly before 1.15pm, a homemade incendiary device detonated in the middle toilet cubicle, causing a small fire, which self-extinguished.

Two attendees were in other toilet cubicles at the time of the explosion. The damage bill associated with the targeted attack was $4600.

A search of Fernando’s home uncovered cannabis, ketamine and 28 other homemade incendiary devices in a bag at the end of her bed and in a cardboard box in her bathroom.

Protest ideology, including a post with the words “At free Palestine Melbourne, and disrupt Melbourne” attached, was found on a laptop at the property.

Fernand’s qualification as an engineer enabled her to buy a ticket to the event.
