About the host

who is binge thinking?

Technically, anyone and everyone is Binge Thinking. Guests are from all walks of life. They are mostly Australian, but the show is striving to include as many international guests as possible. To date, we’ve had guests from Nepal, Japan, America, Canada, New Zealand, and The Gambia.

Binge Thinking is brought to life each fortnight by sibling duo Caspar and Nina Roxburgh. The two are true millennials themselves, meaning Binge Thinking 'walks the walk' while 'talking the talk'. Caspar is the founding father and host of the show. He started the series when he was 27 after getting frustrated by a lack of younger voices in the global media. He’s now a ripe old age of 30 years old. Nina is the formidable architect (aka producer) of your regular Bingeing, and sits at a young 27 years old.
