Daily follower snapshots from CreatorDB's longitudinal index.
Cadel and Mia are a Sydney-based couple who have built one of YouTube's larger short-form presences by documenting their relationship through daily Shorts. The duo — Cadel and Mia Van Haarlem — grew their audience substantially around couple challenge formats, most visibly the 'siblings or dating' trend, which plays on their close dynamic and generated significant viral traction. Their content sits at the intersection of relationship comedy, light pranks, and lifestyle vlogging, with the occasional longer-form milestone piece — a recent empty house tour marking their purchase of a first home is a notable example of how they weave real-life progression into their feed. Although they are Australian, the vast majority of their audience is based in the United States and United Kingdom, a pattern typical of English-language short-form creators whose content algorithms surface them well beyond their home market.
The channel's audience skews heavily female and concentrates in the 18-to-34 age band, which places them squarely in the demographic most responsive to couple and relationship content. Their engagement rate tracks modestly above the category median for a channel of this scale, and their subscriber base has shown consistent month-over-month growth, suggesting the daily upload cadence is sustaining rather than fatiguing their audience. The absence of a visible legacy sponsor roster at this tier is somewhat unusual, but the rate card implied by their reach and demographics positions them attractively for brands in lifestyle, fashion, home, and relationship-adjacent categories. As they continue documenting adult life milestones — homeownership being the most recent — their content is naturally maturing with their audience, which could open doors to longer-form storytelling and more substantial brand integrations beyond the quick-hit Shorts format that built their base.
Cadel and Mia reaches an audience concentrated in Australia primarily through YouTube, and is best activated via long-form YouTube integrations, Instagram Reels and Stories, TikTok branded content. As a lifestyle creator they map naturally to brands targeting that space. Engagement on YouTube runs around 1.7%, pointing to an audience suited to category-relevant, mid-funnel brand campaigns rather than pure-reach buys.

Cadel and Mia are a couple, not siblings. The mix-up became such a defining part of their online identity that they leaned into it fully — they posted a dedicated "SIBLINGS OR DATING... reveal" video and regularly use the #siblingsordating hashtag, turning audience confusion into one of their most recognizable content angles.
Mia's full name is Mia Van Haarlem. She runs the Cadel and Mia channel alongside her partner Cadel, and her personal Instagram handle is @mia.vanhaarlem for fans who want to follow her individual content as well.
Yes — Cadel and Mia posted a full empty house tour video after purchasing what they described as their dream home. It was one of their bigger milestone uploads, documented as a major life moment shared with their tens of millions of subscribers.
They've teased the origin story on their channel — a post captioned "The day we first met" openly invited fans to request a full story time, signalling it's a moment their audience has been curious about. Nostalgia and relationship backstory are angles they return to regularly in their content.
Their bio explicitly states "This is the ONLY Cadel and Mia account" — a disclaimer that points to impersonator pages using their name and likeness. Creators who scale quickly to tens of millions of subscribers commonly attract fake accounts, so Cadel and Mia pin this warning to help fans identify the legitimate channel.
Dance is part of their brand — both Cadel and Mia identify as dancers — but the channel runs much broader than that. They produce couple challenges, pranks, sketch comedy, and vlogs alongside dance content, making it a general entertainment channel built around their relationship and everyday life.
As of mid-2026, Cadel and Mia are still an active couple and content duo, posting regularly across YouTube, Instagram, and TikTok. Major recent milestones — including purchasing a home together — suggest the relationship and channel are both going strong.
Yes — their YouTube bio explicitly promises new Shorts daily, and consistent daily uploads have been central to how they've built one of Australia's largest YouTube channels. Milestone videos like house tours and reveals are posted on top of that regular Shorts schedule.
The Cadel and Mia channel has surpassed 26 million subscribers on YouTube, placing it firmly in the Mega creator tier and making it one of the largest couple-and-lifestyle channels to come out of Australia. YouTube is their dominant platform by a significant margin over Instagram and TikTok.
Cadel and Mia are based in Sydney, Australia. Interestingly, despite being Australian creators, the majority of their audience comes from the United States and the United Kingdom rather than Australia itself.
