A second Australian has died following a Halloween crowd crush in the South Korean capital last month.

The woman succumbed to injuries sustained during the crush after two weeks.

More than150 people were killed in the tragedy during festivities in Seoul’s Itaewon district.

The Department of Foreign Affairs and Trade said it was providing assistance to the woman’s family.

Sydney film production assistant Grace Rached was the first Australian to die in the days after the tragedy.

Ms Rached’s friend Nathan Taverniti, who was also in the crowd, described it as a slow and agonising crush.

“This crush was not caused by drunk people,” Mr Tavernti said in a TikTok post.

“It was caused by a lack of planning, police force and emergency service.”

The area where the tragedy occurred is popular with young people, expatriates and travellers.

A large group of people surged into an alleyway near local nightclubs, reportedly causing the crush.

South Korean President Yoon Suk-yeol apologised for the disaster and pledged to hold those responsible to account.
