A personalised number plate that appears to reference the October 7 Hamas massacre against Israel has been urgently recalled by an Australian transport authority.

The plates, reading “OCT7TH”, were spotted on a white Ford truck in Sydney earlier this month. Videos of the offensive plates have circulated widely on social media this week.

According to reports, Transport for New South Wales has confirmed that the plates were issued six weeks after the October 7 attack.

The driver has been ordered to return the offensive plates or risk the authorities cancelling the vehicle’s registration altogether.

Authorities reportedly conducted an "urgent investigation" to determine how the number plates were issued and driven around for months without being noticed.

According to the Australian Daily Telegraph, number plate provider myPlates, which is responsible for providing all custom plates in NSW, received a complaint on January 23 about the plates but Transport for NSW was not made aware of the complaint until questions were put by to them on Wednesday.

Road Minister John Graham told 2GB's Ben Fordham, "It is coming off the road, and coming off the road rapidly."

"We are determined not to let people drive around sowing division, and that is why we are going to recall these plates urgently.

"We don't know the story behind it but whatever the story is, this is something that if people saw it they would be upset and we want it off the road rapidly."

Graham said Transport for NSW has issued an order for the plates to be recalled, and the usual month-long process had been expedited.

" The request is that these plates are in within 48 hours - it might take up to a week," he said.

"If they don't come back in, the registration will be cancelled altogether."

The Executive Council of Australian Jewry (ECAJ) called for the plates to be retracted.
