Social Media Manager vs In-House Team: Which is Better?
You have been working with an agency for 18 months and the results are solid. Social media is running well and your account looks genuinely good. But the business is growing, the content volume is increasing, and you are starting to wonder whether you should bring someone in-house instead. At the same time, hiring your first marketing employee is a real decision with real costs and real management overhead. Both feel like the logical next step. Only one is the right one for your specific situation.
Here is how to think through it clearly.
What In-House Actually Costs
A full-time social media coordinator in Adelaide earns between $55,000 and $75,000 per year based on SEEK salary data from 2026. Add superannuation at 11.5% and that becomes $61,300 to $83,600. Add recruitment costs: a job ad, a recruiter if you use one, and the time your leadership team spends interviewing. Add onboarding: two to four weeks before the person is independently productive, longer before they understand your brand well enough to produce content that sounds like you.
Add the tools they need to do the job. A scheduling platform with approval workflows costs $50 to $150 per month. A design tool like Adobe Creative Cloud or Canva Pro runs another $50 to $100. Analytics reporting tools, if you want anything beyond the native platform dashboards, add more. The subscription bill for a single in-house social media person quickly reaches $3,000 to $5,000 per year before they produce a single post.
Add leave cover. When your social media coordinator takes annual leave, sick leave, or parental leave, someone else has to manage the account or it goes quiet. For a business that has built an audience expecting regular content, a three-week gap is a real cost.
The realistic total cost of a single in-house social media coordinator, including salary, super, tools, recruitment, and leave overhead, runs $70,000 to $90,000 per year. For that you get one person, almost certainly a generalist, almost certainly without a professional photographer included.
What an Agency Costs for Equivalent Output
A mid-tier agency managing social media, photography, and paid amplification for a small-to-medium Adelaide business typically charges $1,500 to $3,000 per month. That is $18,000 to $36,000 per year.
For that fee you get a team: a strategist, a photographer, a copywriter, and an account manager. The photography is built in. The strategic oversight comes from someone who has managed 20 or 30 accounts and knows what works in your category. The scheduling tools, design licences, and analytics platforms are already built into the agency's operations; you do not pay for them separately.
The cost difference is significant. A mid-range agency engagement at $2,000 per month costs $24,000 per year. A junior in-house coordinator costs $70,000 per year minimum. That gap buys a lot of photography.
When In-House Makes Sense
In-house social media starts to make genuine sense when your content volume outgrows what an agency visit model can produce. If you run multiple venues, multiple brands, or a business where something worth capturing happens every day, a person embedded in the business will produce content volume and freshness that a monthly shoot cannot match.
The best in-house social media hires are people who are physically inside the business: capturing the lunch service, photographing the new product the day it arrives, going live on a Sunday afternoon when something spontaneous is happening. An agency that visits once a month cannot do that. The proximity benefit is real.
In-house also makes more sense when your content requires product knowledge that takes months to acquire. Some businesses have genuinely complex products or services where the social media person needs deep understanding to write accurate, credible content. That kind of knowledge transfer takes time, and an agency model built around monthly briefs does not always support it well.
If you are ready to build a marketing department, not just a social media function, an in-house hire can anchor that. But one person doing social media is not a marketing department. It is one person doing social media.
When an Agency Makes More Sense
For most Adelaide SMBs, an agency remains the better choice at the point when they are first considering this question.
You want photography included and managed without your involvement. You want strategy plus execution, not just a posting schedule that needs constant direction from you. You want flexibility: an agency scales up and down as your needs change, while an employee's contracted hours and responsibilities do not. You want accountability built into the contract, not managed through a performance review cycle.
The question most business owners do not ask is how much time they will spend managing an in-house person. An agency comes with its own management structure. Your account manager coordinates the team. You see content before it goes out and approve it. The management overhead is predictable. An in-house employee needs direction, feedback, a clear brief every month, and someone to escalate problems to. That is a real time cost on top of the salary cost.
The Hybrid Model
Growing businesses at a certain size often land on a hybrid: an in-house coordinator handling day-to-day community management and event content capture, plus an agency managing strategy, photography, and paid media.
This works well because it combines the proximity benefit of in-house with the specialisation benefit of agency. The in-house person captures the spontaneous, responds to comments in real time, and keeps the account active between shoots. The agency produces the high-quality photography, manages the content calendar and strategy, and handles paid amplification.
The split works best when the responsibilities are clearly defined and there is no duplication. The worst version of this hybrid is when the in-house person and the agency are both producing content with no coordination between them, and the account ends up looking inconsistent.
The Hidden Cost That Most Businesses Underestimate
Management time is the most consistently underestimated cost of in-house social media. An agency comes with its own internal management structure. When something goes wrong, the account manager handles it. When the photographer does not deliver, the agency finds a replacement.
When your in-house social media person is stuck, unmotivated, or producing content that is not landing, that problem sits with you. You need to identify it, address it, and either fix it or make the hire again. That cycle is time-consuming and expensive in ways that do not appear on any invoice.
Adelaide Socials also works with businesses that have decided to go in-house and want their team trained to the same standard. If you have made the call to hire internally and want the incoming person to start with a proper foundation, get in touch and we can talk through what that looks like.
