$1m reward to catch Toyah's alleged killer

A $1 million reward has been offered to find and catch a runaway suspect believed to have murdered Toyah Cordingley on a Queensland beach before fleeing to India.

It is the largest reward in the state's history and will be paid to anyone, anywhere in the world for Mr Singh's location and arrest but not his conviction.

The huge payout is the tempting equivalent of more than 53 million rupees in Mr Singh's home country where the average annual salary is just over three million rupees a year.

The reward will be widely promoted in India, and Queensland police receiving tips directly through a WhatsApp link.

Three detectives have travelled to India ready to follow any leads with local authorities.

It has been four years since 24-year-old Ms Cordingley was found in the dunes of Wangetti Beach, north of Cairns, after what police called "a personal and intimate attack".

Her father found Toyah's body a day after the pharmacy worker and animal shelter volunteer failed to return home after taking her dog for a walk in October 2018.

Mr Singh, who worked as a nurse in Innisfail, boarded a plane for India two days later.

In a video statement, Toyah's mother Vanessa Gardiner desperately hoped the reward would bring her daughter's killer to justice.

"I can't believe that it's million dollars, but Toyah deserves that, she deserves every bit of it," Ms Gardiner said.

"And I just hope that I get that call very soon to say that they found him.

"To anyone that knows where he is, please turn him in. If he sees it, I wish he would come forward and turn himself in."

Dad Troy Cordingley said even justice would not bring back the life and future stolen from his daughter.

"She will never get the chance to live, laugh and love. Never get the chance to have children or grandchildren, to grow old," he said.

"This person is right now living free with no consequences for their terrible crime.

"Justice is the very least that she deserved. At the very minimum, this person must be removed from society and held accountable for their crime."

Detective Acting Superintendent Sonia Smith on Thursday said a dedicated team of detectives from Cairns, Far North and the Homicide Investigation Unit continued to work tirelessly towards ensuring justice for Toyah and her family.

"We strongly believe there are people in Australia and overseas who could share information about the whereabouts of Rajwinder Singh," she said.

"This is most definitely the time to come forward and tell us what you know. We are providing someone one million reasons to come forward and tell us his location."

Australian authorities made an extradition request to Indian authorities for Mr Singh in March 2021. However, the wanted man had not been located.

Mr Singh lived in Innisfail but is originally from Buttar Kalan, Punjab.

Deputy Commissioner Tracy Linford said this was the first time an initial reward of $1 million had been offered in Queensland.

"It is critical we capture the attention of an international audience to reach this individual," she said.
