What started as a way for a pair of brothers-in-law from Mildura to pass the time during lockdown has turned into a social media sensation.
Kyran O'Connell and Bill Cooper's TikTok videos, which showcase their friendship, sense of humour and dance moves have earned them hundreds of thousands fans and led to national TV appearances.
The pair, who have more than 500,000 followers on the video platform, have been overwhelmed with the response their simple Brother Boys concept has received — and it all started with an unexpected viral hit.
"Twenty-three million people saw the first video we uploaded to TikTok and it's just grown ever since," O'Connell, 32, said.
Now the Brother Boys are regularly stopped for autographs and selfies by people who've felt better by watching their videos.
"We just enjoy each other's company and I guess people just [enjoy] watching the connection we have," O'Connell said.
"[The COVID-19 pandemic] has been really stressful and emotional, so we encourage people to do whatever it is that makes themselves and others feel better.
Cooper, 25, says he just wants to "make people smile, crack jokes and have a dance".
'I'm a role model'
The Brother Boys believe the inclusivity of their brand has allowed them to cut through in the overstuffed TikTok market.
The pair now have an agent and were recently featured on SBS's Insight program.
"I'm a role model to kids with Down Syndrome," Cooper said.
O'Connell says he and Cooper are an odd couple no-one saw coming.
"You wouldn't expect a duo like us two," he said.
"It's the diversity — I think that's what people appreciate and the response has been so positive."
While they're delighted with their success, it's still something the men are coming to grips with.
"They are flying us around the place, sending us free things," O'Connell said.
