Social Media Marketing Agency vs In-House Team: Introduction
Building a dynamic and powerful media presence is not just an option for Melbourne businesses. If you are trying to boost brand awareness, engagement, generate qualified leads, and drive higher sales, social media has become one of the most significant and popular digital marketing platforms. Business owners nowadays have one common doubt: whether they should hire an in-house team or partner with a social media marketing agency!
Both can help you grow your business. But when it comes to cost, scalability, expertise, and long-term business ROI (Return on Investment), you can see the difference. Hiring a social media marketer or an in-house team can give you internal resources. On the other hand, partnering with an agency gives you direct access to a team of industry experts without even paying them for full-time employment.
In this article, I am going to compare the major financial and operational factors that Melbourne businesses must consider when choosing the best option for achieving their desired marketing goals.

Which Delivers Higher ROI?
1. High Victorian Overhead & Payroll Costs
One of the significant differences in hiring an employee or in-house team and partnering with a Social Media Marketing Agency Melbourne is the costing. Hiring a full-time employee can lead to regular business expenses for extra employment costs.
In-House Social Media Manager
A professional Social Media Manager in Melbourne usually gets up to AUD $80,000 – $100,000 yearly as an average salary. The total employment cost can reach approximately AUD $115,000 a year after adding additional employee expenses like WorkCover Victoria insurance, recruitment training, 12% superannuation, paid leave, and office equipment.
Social Media Marketing Agency
Some Melbourne agencies generally charge approximately AUD $800 to $5,000 monthly, based on the type of services and support level. These social media marketing service packages might include content creation, campaign management, strategy building, paid advertising, and regular performance reporting.
Small businesses with a tight budget can hire Impact Media Oz to get affordable service packages starting from AUD $300 monthly. They can give your business easy access to professional services at an affordable pricing.
2. Tool Costs
An excellent social media marketing strategy depends on professional and advanced software for post scheduling, content creation, performance analysis, and campaign management. Having paid access to these tools can increase the overall business operating cost.
In-House Social Media Manager
An in-house team or employee might need a paid or premium subscription plan for tools like
- Adobe Creative Cloud
- Canva Pro
- ChatGPT paid version
- Buffer
- HootSuite
- Sprout Social
- Scheduling tools
- Video editing tools
- Analytics platforms
Social Media Marketing Agency
Some agencies already took subscriptions to premium marketing tools and add access to their service. Businesses get free access to paid enterprise-level software without even purchasing it or personal subscriptions. This reduces both the administrative tasks and overall costing.
So, choosing a social media marketing agency can be a wise investment.
3. Skill Set
Successfully managing social media accounts needs industry expertise across different backgrounds, from creating content to analytics and advertising. You can’t expect one person to have multiple skills or mastery over various disciplines can be unrealistic.
In-House Social Media Manager
Being an in-house social media marketing manager, you are assigned to different roles such as;
- Graphic design
- Video editing
- Content creation
- Paid advertising
- Copywriting
- Performance reporting
- Community management
It is very difficult for an individual to specialise in multiple areas.
Social Media Marketing Agency
A social media marketing agency offers businesses the acces to a team of industry experts such as a social media marketing specialist, graphic designer, video editor, advertising expert, copywriter, and analyst. Each professionals have expertise in their specific areas, and they help you create high-converting campaigns and deliver improved marketing performance.
So, a social media marketing agency is clearly the winner here.
4. Ramp-Up Time
Planning an effective social media marketing strategy needs time, particularly when you are hiring someone. Starting from recruiting to onboarding, this process can delay social media campaigns and slow business growth.
In-House Social Media Manager
Hiring internally typically involves multiple stages before marketing activities even start. Those cover;
- Advertisement for the position
- Application review
- Conduct interviews
- Recruitment completion
- Employee notice periods
- Employee training and onboarding
Usually, this process takes 5 to 8 weeks for most of the businesses. New hirings might require extra time to understand company goals, products, services, and brand message before even planning social media strategy or delivering higher business results.
Social Media Marketing Agency
A social media marketing agency in Melbourne can start working immediately after onboarding. As agencies have industry-experienced professionals and pre-built workflows, they can make effective strategies quickly, create engaging content, and launch social media marketing campaigns without a longer training period or recruitment process.
5. Best For
You can choose the right one based on your business size, marketing goals, brand voice, and resources. Both options have their unique benefits and are best for different types of businesses or company sizes.
In-House Social Media Manager
Internal hiring can be the best option for businesses that;
- Have a larger in-house marketing team
- Require regular on-site content creation
- Need consistent collaboration among each department
- Generate high volumes of product visuals or video content
Social Media Marketing Agency
A social media marketing agency is best for;
- Local, small or mid-sized businesses
- E-commerce brands
- Startups
- Businesses that want measurable ROI
- Professional service providers
Rather than depending on an in-house team or an individual employee, businesses directly take services from a professional team or agency to manage predictable marketing
6. Favourable Tax Structure for Agencies
Financial choices also impact whether businesses go with an in-house agency or hire an external marketing agency, beyond marketing performance.
In-House Social Media Manager
According to the State Revenue Office of Victoria website, businesses located in Victoria are subject to pay 4.85% tax on payroll if their wages are taxable, which is above AUD $1 million. Payroll duties grow with insurance, superannuation, and related employment costs as more employees are hired.
Social Media Marketing Agency
Agency hiring expenses are usually marked as operating expenses, not as payroll costs. This means your business can invest in professional services without paying higher payroll taxes. While each business depends on an accountant for advice on tax matters, outsourcing offers you more flexibility than spending on an external team.
7. Victorian Fair Work & Leave Compliance
Hiring employees comes with many legal and administrative duties and is not limited to paying salaries.
In-House Social Media Manager
Businesses should follow Australian employment norms and regulations like;
- Personal leave: 10 days
- Annual leave: 20 days
- Public holidays
- Performance management
- Fair Work Act Compliance
- Long-service leave entitlements
- Employment termination processes
Managing such duties needs additional HR resources and time, which is difficult, especially for small businesses without a well-organized and professional HR team.

Social Media Marketing Agency
While partnering with an agency, the above-mentioned employer duties remain under the agency itself. Businesses get uninterrupted marketing assistance without thinking much about leave policies, recruitment, Compliance, or employment rules and regulations.
This drastically lowers operations issues and enables business owners to focus more on running their businesses than handling in-house employment problems.

Final Thoughts,
One-size-fits-all rule is not applied when choosing the best marketing team for your business, whether it’s an in-house team or hiring a professional social media marketing agency. Always choose according to your business size, budget, marketing objectives, and internal resources.
An in-house team is the best fit for large organizations where daily on-site content generation is needed, and there is easy collaboration among different teams. But for Melbourne small or mid-sized businesses, hiring a social media marketing agency offers higher value by minimizing additional employment expenses.
