Sydney influencer known for his 330,000 followers as “Humdinger” died after reportedly consuming cocaine laced with opioids.

Tributes have flowed for Australian social media influencer Dunka Raymond Caldwell, known for his 330,000 followers as “Humdinger”, who has died after reportedly consuming cocaine laced with potent opioids.

The Daily Telegraph reported Caldwell, from Sydney’s inner-west, was found dead at his Glebe home on August 30.

His close friend, 43-year-old Angel Mounce-Stephens, was found dead hours later in her Newtown residence.

Their deaths follow NSW Health’s public warning about contaminated drugs circulating in the area, especially those tainted with potent opioids.

Social media has been flooded with tributes following Mr Caldwell and Ms Mounce-Stephens’ deaths.

“Heartbreaking news... May your soul rest in peace both of you. My condolences go out to the Caldwell/Fernando families, feeling for you mob,” former boxer and NRL star Anthony Mundine posted Facebook.

Sydney influencer Dunka Raymond Caldwell, known to his 330,000 followers as “Humdinger”, has died after reportedly consuming cocaine laced with potent opioids.

Family and friends have remembered Mr Caldwell as a “loving guy” who strived to help others.

“Absolutely devastated to hear of your passing. Everyone in our community has a heavy heart today and the world is a little less bright without you... Thank you for being the life of the party and supporting me,” friend of the family Shanell Dargan wrote.

“You were my big brother on TikTok and I’ll never forget the extra mile you’d always go for me... Thank you for always being so positive,” influencer Jasmin Mitwali said.

“Can’t believe Humdinger is gone. Such a fun loving guy, very positive and I loved watching his videos, condolences to family and friends,” another wrote.

NSW Health chief addiction medicine specialist Dr Hester Wilson said heroin overdoses could quickly result from a single line.

“It is important that people recognise the signs of an opioid overdose early and know-how to respond,” he said.

Caldwell, from Sydney’s inner-west, was found dead at his Glebe home on August 30.

“Opioids such as heroin can cause pinpoint pupils, drowsiness, loss of consciousness, slowed breathing/snoring and skin turning blue/grey and can be life-threatening.

“Heroin and other opioids can be sold as or found in cocaine, methamphetamine, and MDMA (ecstasy).

“You cannot always tell the difference between these drugs by appearance.

“In light of this detection, people who use drugs such as cocaine, methamphetamine, MDMA or opioids should carry naloxone.”

Anyone who witnesses someone experiencing unexpected symptoms after using drugs should call triple 0 immediately, or seek urgent medical care.

Experts also suggest people carry naloxone which should be given immediately as an important lifesaving medication that reverses the effect of opioids.

Naloxone does not require a prescription and is free for anyone at risk of opioid overdose in NSW.

It is available as an easy to use nasal spray or injection from some pharmacies and other health services.
