In this episode of What’s the 411?, we sit down with Winston Hong — Australia’s most well-known Brazilian Jiu-Jitsu referee and the man behind Ace Academy BJJ in Leichhardt. Winston shares what it’s really like to officiate at some of the country’s biggest competitions, the challenges of staying sharp and fair in a fast-growing sport, and his perspective on how BJJ is evolving across Australia. We also dive into his journey from the mats to the referee’s chair, what inspired him to open his own gym, and his vision for building the next generation of grapplers. Whether you’re a competitor, coach, or fan of the sport, this episode gives you an inside look at the side of BJJ most people never see.

#011 - Richard McGlinchey

In this episode of What’s the 411, we dive into the extraordinary life of a veteran saturation diver Richard McGlinchey who has spent years working in some of the most extreme and unforgiving environments on Earth—hundreds of meters below the ocean’s surface. He shares what it’s really like to live and work deep beneath the sea, the challenges and dangers of the job, and the mindset required to thrive in such high-pressure conditions. Beyond the depths, he’s also a longtime Brazilian Jiu-Jitsu practitioner, and we explore the surprising connections between training on the mat and working under immense pressure in saturation chambers. From discipline and resilience to the importance of teamwork, his story offers a rare look into a life lived on the edge. If you’ve ever wondered what it takes to balance a career in one of the most dangerous professions in the world while pursuing the art of BJJ, this conversation is for you.

As a professional firefighter and one of Australia’s top female Brazilian Jiu-Jitsu athletes, Sirena is no stranger to pressure, on or off the mats. We dive into her journey to the top, including her team switch, the mindset and grind behind becoming a champion, and what’s next in her competitive career.

#008 - Peter "The 411 Accountant" Economos

Receipts & Rear-Nakeds: This week we chat with an accountant who knows the ATO like the back of his calculator and has helped everyone from small business battlers to big-name ballers stay on the right side of the taxman. But when he’s not knee-deep in spreadsheets, he’s mat side cheering on his kids in Brazilian Jiu-Jitsu. We talk about why he thinks BJJ is one of the best things you can do for your kids (and maybe even your tax strategy?), the surprising crossover between business smarts and combat sports, and what it’s like explaining GST while watching a gi choke. It’s part finance, part parenting, part flying armbar and all good chat.
