Mia Stellard opened Saltline Studio in a converted warehouse on Donnison Street, Gosford, eighteen months ago with $140,000 in personal savings and a thesis: that brands paying for AI-generated influencer content were buying a time bomb. As of this week, the detonator looks closer than ever.
Meta's sweeping purge of millions of accounts — many operated by AI systems impersonating real creators — sent shockwaves through the influencer marketing industry globally on July 4. For Stellard, 34, it validated a business model she had been quietly pitching to Central Coast retailers and hospitality operators since January 2025. Saltline Studio now holds contracts with eleven local clients, with a monthly recurring revenue run-rate of approximately $68,000, according to figures provided to The Daily Central Coast.
The timing matters because the Central Coast's commercial strip is at an inflection point. Vacancy rates on Mann Street in Gosford's CBD hovered around 19 percent as recently as mid-2025, according to data from the Central Coast Council's economic development unit. Businesses that survived the post-pandemic churn are now being asked to compete in a digital environment where the rules keep changing overnight. Stellard's argument — that hyper-local, human-verified content builds the kind of trust no algorithm can fake — is landing with owners who have watched social media ad spending eat their margins for three years without clear returns.
What Saltline Actually Does
The studio operates across two disciplines. The first is content production: short-form video, photography and copywriting created by a team of eight local contractors, most of them based between Erina Fair and Terrigal. The second, newer arm is what Stellard calls an "authenticity audit" — a structured review of a client's existing social media presence to identify AI-generated or outsourced content that could trigger platform penalties under the tightening policies now rolling out from Meta, TikTok and Google.
That audit service, priced at $2,400 per engagement, has generated 23 bookings since February. Clients include two hospitality venues on The Entrance waterfront and a building supplies company based in the Somersby Industrial Estate. Stellard declined to name them, citing confidentiality clauses, but confirmed all are registered Central Coast businesses with annual turnovers above $1 million.
The studio is also a formal delivery partner under the NSW Government's Small Business Digital Adaptation Program, which provides eligible businesses with subsidised access to digital tools and advisory services. That accreditation, granted in March, has funnelled an additional nine referrals to Saltline through Service NSW's Gosford office on Donnison Street.
The Harder Question
Not everyone is convinced the model scales. Digital marketing specialists elsewhere on the Coast point out that Saltline's pricing — a typical monthly retainer runs between $3,500 and $6,000 — puts it out of reach for the micro-businesses that make up the bulk of the region's 22,000-plus registered enterprises. The Central Coast Business Review, published quarterly by the Central Coast Industry Connect group based in Tuggerah, flagged in its June 2026 edition that fewer than 12 percent of local SMEs allocate more than $2,000 per month to digital marketing of any kind.
Stellard's response is a tiered entry product she plans to launch in September: a $799 per month package aimed at sole traders and cafes, built around templated content sprints and a monthly 90-minute strategy call. She has already taken deposits from seven businesses, including a surf school operating out of Avoca Beach and a specialist food retailer on the Gosford waterfront precinct.
For business owners watching the AI content landscape destabilise, the practical move is straightforward: audit your existing social accounts before the platforms do it for you, document the human origin of any creator relationships, and get clarity on whether your marketing agency is using generative AI to produce work billed as original. The Central Coast Industry Connect group runs free monthly briefings at its Tuggerah office — the next is scheduled for July 22 — where platform policy changes are a standing agenda item. Whether Saltline or any other local studio ends up capturing the anxiety in the market, the underlying pressure is real and accelerating.
