Social media marketing for law firms in Australia

Content11 min readReviewed 11 September 2026

Platform choice follows practice area: LinkedIn for commercial and business law, Facebook for community-facing areas like family law, conveyancing and wills, Instagram where human storytelling fits. Twice a month sustained beats daily for six weeks then nothing, and every post is advertising under the conduct rules.

Most law firms treat social media as an obligation rather than a strategy: someone in the office set up a Facebook page years ago, posts happen in irregular bursts, and nobody’s quite sure what it’s meant to achieve. That’s a shame, because when it’s run properly, social media for lawyers is one of the cheapest ways to reinforce the trust that search rankings and reviews have already built. It’s a poor lead-generation channel on its own, our social media marketing service page covers that trade-off honestly, but this guide goes deeper: which platforms are actually worth a law firm’s time, what to post, the compliance line most firms don’t realise they’re near, and how each practice area should approach it differently.

Which platforms are actually worth a law firm’s time

Not every platform deserves equal effort, and spreading a small marketing budget thin across five networks usually means all five look neglected. Start from where your actual audience, past clients, prospective clients and referral partners, spends time, not from which platform is trendiest.

Sprout Social’s 2026 Australia social media statistics report that Facebook reaches roughly 78% of Australian internet users and remains the largest single platform by reach, while Searchscope’s 2026 Australian social media data puts LinkedIn at around 18 million Australian members, close to 85% of the country’s adult population, and growing faster year-on-year than most other networks. Instagram sits in between, reaching roughly 15-16 million Australians, skewing slightly female and younger, with 25-34 year-olds forming the largest single age group on the platform.

For most firms, that translates into a simple hierarchy. LinkedIn is close to essential for commercial and business law, where referral partners, accountants and corporate clients are actively watching what your firm publishes. Facebook remains the broadest reach for community-facing practice areas with an older client base. Instagram earns its place mainly where visual, human storytelling fits the practice, think team culture, community involvement, approachable content, rather than legal explainer content. TikTok and X are rarely worth a law firm’s limited marketing hours; the audience skews toward entertainment intent rather than the considered, trust-driven decision-making that legal services require, and the compliance risk of off-the-cuff short-form content is higher than the potential upside for most firms.

A useful test before committing to a platform: would a referral partner or a past client’s friend, checking your firm out after a recommendation, find something current and professional there? If the honest answer is no, that platform isn’t worth maintaining yet, better to run one channel well than three badly, a principle covered in more depth in our complete law firm marketing guide.

What to actually post: content ideas, cadence and tone

Generic advice says "post consistently" without saying what to post. In practice, content that works for law firms tends to fall into five categories, and a healthy monthly calendar rotates through most of them rather than leaning on just one:

• Legal updates in plain language: a change to family law parenting arrangements, a new conveyancing disclosure requirement, an update to sentencing guidelines. Written for a worried client, not a colleague.
• Team and culture content: introducing a new solicitor, a photo from a community event, a short note on why someone joined the firm. This is what builds the "people behind the firm" trust that matters most for family law and wills and estates clients specifically.
• Answers to real client questions: the same questions your reception fields every week make excellent, genuinely useful posts, "do I need a lawyer to review a lease", "what happens if I’m charged with drink driving". These also tend to double as content that supports your broader SEO efforts when repurposed on the website.
• Community involvement and sponsorships: local sporting clubs, charity events, chamber of commerce activity. Especially valuable for firms relying on referral marketing within a defined geographic patch.
• Firm milestones and recognition: a case win described in general terms (never with outcome guarantees), an award, an accreditation. Used sparingly, these carry real weight precisely because they’re not overused.

On cadence: twice a month, posted consistently for a year, does more for credibility than daily posting for six weeks followed by silence. Prospective clients and referral partners notice gaps far more than they notice frequency, an abandoned-looking profile actively damages trust rather than simply doing nothing. Tone should match your brand identity and the rest of your website, professional but human, plain language over legalese, and specific to your practice areas rather than generic "did you know" filler that could belong to any firm in the country.

Professional conduct and advertising rules on social media

Social media doesn’t get a compliance exemption because it feels informal. The same restrictions that apply to any advertising under the Legal Profession Uniform Law and state-based conduct rules apply in full to a Facebook post or an Instagram caption, and it’s easy to breach them without realising, particularly with case results, client testimonials or specialisation claims. Our legal advertising rules guide covers the framework in detail, but the practical points that matter most for social content are:

• Avoid anything that could be read as a guarantee of outcome, "we’ll win your case" or similar, even implied through imagery or emoji.
• Be careful publishing specific case results, even truthful ones, without checking your state’s rules on client confidentiality and outcome advertising.
• Client testimonials and reviews shared on social media need to comply with the same rules as testimonials anywhere else, some jurisdictions restrict solicited testimonials about the character or skill of a legal practitioner.
• Content that could be read as legal advice to a specific situation, rather than general information, needs a clear disclaimer.
• Every post should be reviewed by someone who understands both your state’s rules and how social platforms tend to strip context from a caption when it’s shared or screenshotted.

This is the single biggest reason law firm social media shouldn’t be handed to a junior staff member with no review process. A well-run programme builds compliance review into the calendar before anything is scheduled, not after a client raises a concern.

LinkedIn vs Instagram vs Facebook, by practice area

The right platform mix genuinely differs by practice area, more than most generic social media advice acknowledges. See how it breaks down below:

Family law. Best platforms: Facebook first, Instagram second. Why: family law clients are searching in an emotional, often stressful moment and respond to warmth and approachability more than credentials. What to post: plain-language explainers on parenting arrangements and property settlement, team introductions, and community involvement that signals a supportive, human practice rather than a courtroom-only one. See our family law marketing page for the broader channel mix.

Personal injury. Best platforms: Facebook, with Instagram for community-facing content. Why: personal injury clients are usually referred or searching locally after an accident, trust and local reputation matter more than professional networking. What to post: plain-language guides on claim timeframes and entitlements, workplace safety awareness content, and client-consented outcome stories written to stay well inside advertising rules. Full detail on this channel mix sits on our personal injury marketing page.

Conveyancing. Best platforms: Facebook and Instagram, community and referral-partner focused. Why: conveyancing decisions are local and often involve a referral from an agent or mortgage broker who checks the firm out first. What to post: settlement timeline explainers, first-home-buyer tips, and content that keeps real estate agents and brokers aware the firm is active and reliable. See our conveyancing marketing page for the full referral-partner strategy.

Wills and estates. Best platforms: Facebook primarily, occasionally LinkedIn for professional referral partners like financial planners. Why: this is one of the most trust-and-relationship-driven practice areas, clients want a sense of the people involved before they call. What to post: plain-language estate planning basics, team content, and gentle prompts about reviewing an outdated will, never anything that could read as pressure. Our wills and estates marketing page covers the wider approach.

Criminal law. Best platforms: Minimal social media investment generally, a well-maintained Facebook presence is usually sufficient. Why: criminal law clients are almost always searching urgently and locally rather than browsing social content, and the compliance risk around case specifics is higher than in most other practice areas. What to post: general legal process explainers (what happens after an arrest, what a first court appearance involves), kept strictly general and reviewed carefully. See our criminal law marketing page for where budget is better spent.

Commercial law. Best platforms: LinkedIn, almost exclusively. Why: commercial and business law clients, and the accountants and advisors who refer them, are professional-network users first. Sprout Social’s Australian data and industry research on B2B buyer behaviour both point to LinkedIn as the platform where corporate decision-makers actually evaluate who to engage. What to post: thought leadership on regulatory change, contract and compliance updates relevant to business owners, and genuine commentary rather than generic corporate filler. Our commercial law marketing page covers the full channel strategy.

How to measure results without vanity metrics

Follower counts and likes feel like progress but rarely correlate with anything a firm actually cares about. A more useful scorecard looks at:

• Reach and engagement trend over time, not any single post, whether the overall trajectory is upward and consistent, which indicates the content is resonating with the right audience.
• Direct enquiries traced to social, tracked through a dedicated link, promo code or simply asking new enquiries how they found the firm.
• Referral partner feedback, informal but genuinely valuable, a broker or accountant mentioning they saw a recent post is a real signal even if it doesn’t show up in a dashboard.
• Website traffic from social as a supporting channel, visible in analytics alongside organic search and paid traffic.
• Consistency itself, whether posts are actually going out on schedule, since an abandoned profile is worse for credibility than no profile at all.

Some research on legal consumer behaviour suggests a large majority of people check a lawyer’s online presence, including social profiles, before making contact, which is why these credibility-focused metrics matter even when direct lead volume from social stays modest. If a firm wants social media purely as a lead-generation engine, Google Ads or local SEO will almost always outperform it on that specific measure; social media’s job is different, and it should be judged on the numbers that actually reflect that job.

Should individual lawyers post, or just the firm?

Both, but they do different jobs. A firm page is where someone checks that the practice is real and current. An individual lawyer’s profile is where people actually connect, follow and form an impression of who they’d be dealing with, and on LinkedIn in particular, posts from a person consistently reach further than the same content from a company page.

For commercial and business law, individual partner profiles usually matter more than the firm page. Practical steps: make sure every lawyer’s profile lists the correct firm, role and practice areas; encourage the two or three people who genuinely enjoy it to post rather than mandating it across the whole team; and be explicit that professional conduct rules apply to a personal profile that identifies someone as a solicitor. A partner’s off-the-cuff comment on a matter type is still advertising if it promotes the practice.

A short internal social media policy is worth writing once. It should cover who may post as the firm, what needs review before publication, what nobody discusses publicly (current matters, opposing parties, anything a client told them), and what to do when someone describes their legal problem in the comments, which is: acknowledge briefly, never advise, invite them to call.

Is paid social worth it for a law firm?

Organic social and paid social are different products. Organic reaches people who already have some connection to the firm. Paid social reaches people who are not looking for a lawyer at all, which is precisely why it converts far worse than search, where the person has actively typed a problem into Google.

That said, paid social has three jobs it does well for a law firm: promoting a genuinely useful guide or seminar to a defined local audience; remarketing to people who already visited the website but didn’t enquire; and building awareness in a specific suburb where the firm is new and unknown. Budgets can be small and results should be judged on cost per enquiry, exactly as with Google Ads.

One serious caution specific to legal: be extremely careful with targeting that could imply knowledge of someone’s circumstances. Audiences built around recent injury, relationship changes or financial distress sit uncomfortably close to the conduct rule against approaching people at a significant disadvantage, quite apart from platform policies on sensitive categories. Publishing useful information that people choose to engage with is very different ground from targeting them because something has happened to them.
