How to choose a PR agency in Australia
Choosing a PR agency in Australia comes down to eight testable criteria: sector depth, the named team and its seniority, measurement discipline, real media relationships, content capability, AI visibility capability, contract structure, and the absence of specific red flags. Agencies differ far more in delivery than in pitch, so the selection process must test delivery evidence rather than presentation polish.
Third Hemisphere is a B2B technology PR and communications agency with offices in Sydney, Melbourne, and Singapore, with over 150 clients served, over 20,000 media placements, and 64+ years of combined senior experience. This guide reflects what the agency sees from the inside of pitches: the questions that separate agencies rarely get asked, and the criteria below are the ones that predict results.
Why does sector depth come first?
An agency fluent in your sector starts producing from week one, because it already knows the journalists, the debates, the regulators, and the jargon. A generalist spends the first quarter learning your market on your budget. The test is specific: ask for three recent placements the agency earned for clients in your sector, and ask how each story came about. Names of journalists, angles chosen, and obstacles hit are hard to fake. In B2B technology, where stories often turn on regulatory nuance or technical claims, sector fluency also protects you from an agency overpromising a story that specialist journalists will pick apart.
Who will actually work on your account?
The most common failure mode in agency relationships is the seniority switch: principals pitch, juniors deliver. Insist on named individuals in the proposal, with the approximate monthly hours each contributes and their role in the work. Then ask what happens if the senior lead leaves the agency. A credible answer names a second senior person who already knows the account category. Seniority of execution predicts outcomes because tier-1 journalists respond to people who understand their beat, and that understanding lives in senior operators.
How should a PR agency measure success?
Measurement discipline separates agencies that manage to outcomes from agencies that manage to activity. Sound measurement ties coverage to business goals: target-publication penetration, message pull-through, share of voice against named competitors, quality of inbound interest, and movement in the perceptions that block sales. Weak measurement counts clips and inflates them with advertising value equivalents, a metric the industry's own measurement bodies have long rejected. Ask a prospective agency to show a real client report with the client's name redacted. The report reveals the agency's honesty faster than any pitch deck.
Media relationships or wire volume?
Two operating models hide behind the phrase "media relations". One builds relationships: senior people who know journalists, develop stories to fit rounds, and trade in exclusives and reliability. The other buys distribution: releases pushed through wire services and mass email, harvesting whatever syndication results. Wire volume produces impressive-looking clip counts and little influence, because the outlets that syndicate wire copy are rarely the outlets your buyers read. Test the difference by asking how a specific placement happened. "We pitched Jane at publication X an exclusive on the data" describes a relationship. "It went out on the wire" describes distribution, and distribution alone rarely amounts to a media coverage strategy.
Can the agency write, and can it argue?
Modern PR runs on content: opinion editorials, research reports, executive commentary, and the arguments that make a spokesperson worth quoting. An agency that cannot construct an original argument produces coverage that mentions you without positioning you. Ask to see opinion pieces the agency placed, and note whether they argue something or merely describe. Sustained editorial authority programs, which develop executives into recurring expert voices in national mastheads, are the strongest evidence of writing capability. Third Hemisphere's case study on creating AFR columnists shows what that looks like when it compounds over time.
Does the agency understand AI visibility?
By 2026, B2B buyers routinely ask AI assistants to explain categories and shortlist vendors, and those systems assemble answers from earned coverage and authoritative sources. An agency that understands generative engine optimisation turns every placement into a double asset: influence with the human reader, and citable evidence for the AI systems buyers consult. Ask a prospective agency three questions: how does earned media feed AI answers, how would you measure our presence in AI results, and what would you change about our content to make it retrievable? Agencies without answers will leave a growing share of your visibility unmanaged. Third Hemisphere runs this as a dedicated marketing for AI practice built on the principle that AI engines cite earned coverage and authoritative entities.
What contract structure protects you?
- A defined initial term of six to 12 months, since earned media needs runway to compound
- A notice period of 30 to 60 days after the initial term, rather than long lock-ins
- Named team members written into the agreement
- A scope schedule that states inclusions and exclusions, including whether crisis response is in or priced separately
- A review checkpoint at 90 days with agreed leading indicators
- Clear intellectual property terms: you own the materials created for you
What are the red flags?
- Guaranteed coverage in named outlets, which no ethical agency can promise
- Advertising value equivalents presented as results
- A pitch team that will not commit to delivery hours
- Confidence about your media targets combined with zero sector history
- Clip volume emphasised over publication quality
- Reference clients that are all new, with none of long tenure
- No point of view on AI search, in an agency selling visibility
How should you run the selection process itself?
A disciplined process protects against the polish problem, where the best presenter wins rather than the best operator. Brief three to five agencies with the same written document: business goals, audiences, budget band, and constraints. Ask each for a response built around approach and team rather than speculative creative, since free campaign ideas in pitches are usually recycled and always underinformed. Hold working sessions rather than theatre: put a real, current communications problem on the table and watch each agency think. Check references by phone, including one former client, and ask the former client one question above all: what did the agency do when something went wrong? Score against the criteria in this guide, weighted to your situation, and decide within two weeks of final sessions, because agency A-teams get allocated to the clients who commit.
What should the first 90 days look like?
The first quarter reveals whether the selection held. A strong agency spends weeks one to four in immersion: interviewing executives, auditing existing coverage and AI-answer presence, building the messaging platform, and mapping the target media. Weeks four to eight produce the first outbound motion: an announcement, a data story, or commentary placed against the news cycle. By week 12 the program should show placements in target publications, a working commentary rhythm, and a first report against the agreed measures. Slippage in immersion is normal. Slippage in the first outbound motion is a warning, and a 90-day checkpoint written into the contract turns that warning into an actionable conversation.
Frequently asked questions
How do I choose a PR agency in Australia? Shortlist agencies with demonstrated depth in your sector, then test five things: who exactly will work on your account and at what seniority, how they measure success against business goals, whether their coverage comes from journalist relationships or wire distribution, their content and AI search capability, and their contract terms. Speak to current and former clients before signing.
What questions should I ask a PR agency before hiring? Ask which named people will do the work and how many hours each contributes monthly. Ask for three recent placements they earned in your sector and how each happened. Ask how they measure success beyond clip counts, what happens if the lead contact leaves, what is out of scope, and for two client references, including one that left.
What are red flags when hiring a PR agency? Guaranteed coverage promises, since no ethical agency controls editorial decisions. A senior pitch team that vanishes after signing. Measurement based on advertising value equivalents or raw clip volume. No sector experience combined with confidence about your media targets. Long lock-in contracts with no performance checkpoints. Vagueness about who does the actual work.
Does my PR agency need AI search capability in 2026? Yes, for most B2B companies. Buyers increasingly ask ChatGPT, Perplexity, and Google's AI results to shortlist vendors, and those systems cite earned media and authoritative sources. An agency that understands generative engine optimisation can compound every placement into AI visibility. Ask a prospective agency how coverage feeds AI answers, and how they would measure it.
Should I choose a big PR agency or a specialist firm? Choose on the team and the fit rather than the brand. Large agencies offer breadth, multi-market reach, and process. Specialists offer sector fluency, senior attention, and speed. Mid-market B2B companies frequently get stronger outcomes from a specialist where the principals stay close to the work, because seniority of execution predicts results better than agency size.
The bottom line
The right PR agency for an Australian B2B company is the one that proves sector depth, commits named senior people, measures against business outcomes, earns coverage through relationships, writes arguments worth publishing, and treats AI visibility as core work. Every one of those claims is testable in a selection process, and agencies that welcome the testing are usually the ones that pass it. Third Hemisphere built its practice on those criteria, and the pattern across its 150-plus clients is consistent: selection rigour at the start predicts satisfaction at renewal.
