PR agency in Sydney

PR agency in Sydney

Third Hemisphere is a PR, communications, and AI visibility agency founded in Sydney in 2015. Our Sydney office at Level 3, 180 George Street sits in the middle of the country's finance, technology, and venture capital community, and the team there has placed over 20,000 stories for over 150 clients across Australia and APAC.

What does Third Hemisphere do in Sydney?

Third Hemisphere runs media relations, editorial authority programs, investor communications, crisis management, content, digital marketing, and AI visibility work from Sydney. Founder and CEO Hannah Moreno and Executive Chair Jeremy Liddle both work from the Sydney office, so a Sydney client gets the agency's most senior counsel in their own city. The team brings 64+ years of combined experience across journalism, communications, and capital markets.

Sydney is where the agency started and where most of its media relationships were built. Our editorial team includes former journalists from the Australian Financial Review, Bloomberg, and technology trade publications, and those relationships are the reason a Sydney pitch reaches a named journalist rather than a news desk inbox.

Companies come to the Sydney team for three reasons. They are raising capital or listing and need coverage that gives investors confidence. They are launching or scaling in Australia and need national media presence. Or they have discovered that AI engines answer questions about their category without mentioning them, and they want the earned media that changes the answer.

Why does a Sydney office matter for fintech and venture-backed companies?

Sydney carries the densest concentration of fintech companies, venture capital firms, and institutional investors in Australia, and the journalists who cover them work the same square kilometre. The Australian Financial Review, The Australian's business desk, and the newswires all report from Sydney, and the fintech and startup trades follow the same deal flow. A story that lands with this group travels: into national mastheads, into investor inboxes, and into the sources AI engines cite.

That density shapes how we work. A Sydney fintech raising a Series B is pitched to the reporters who covered its competitors' rounds. A fund announcing a close is briefed to the journalists its LPs actually read. Our 10-year partnership with MONEYME, which has produced 60+ national placements across business and fintech media, was built this way: one narrative, sustained over years, with the journalists who own the beat.

The same team runs investor communications for listed and pre-IPO companies. For Gelion, we secured Bloomberg, Reuters, and Australian Financial Review coverage ahead of its ASX listing. That work runs from Sydney because the analysts, the financial media, and the exchange all sit here.

Sydney is also home to a deep venture capital and private equity community, and to significant health, life sciences, and professional services sectors. The team runs the same disciplined approach for each: research the buyers, build the narrative, and place it with the journalists who already cover the category, whether the story is a Series B raise, a clinical trial milestone, or a partner profile.

How does Third Hemisphere improve what AI engines say about a Sydney company?

Buyers, investors, and journalists now ask ChatGPT, Claude, Gemini, Copilot, and Perplexity about a company before they form their own view, and the engines answer from the published record. Our Fourth Hemisphere practice measures that record with the PACT diagnostic: 50 real buyer questions asked across the five engines, with every answer scored for Presence, Authority, Consensus, and Truth. You see where you appear, who is named instead of you, and which sources the engines relied on.

The Sydney team then changes those sources. Earned media in the mastheads the engines cite, structured content they can retrieve, and consistent entity data across every third-party record combine into one program, and quarterly re-audits show the answers moving question by question. Our work for Fremantle Seaweed, NeonNow, and an ASX-listed lender shows the method in practice, and each of those case studies is published in full on this site.

The diagnostic runs before we meet and costs you nothing. Book a discovery call, and the Sydney team will present what the engines currently say about you on the call itself.

How does an engagement with the Sydney team work?

Every engagement starts with a conversation and a written scope. You will know the target media, the deliverables, the fee, and the measurement plan before any work begins.

  1. Discovery call A 30 minute call covers your announcement pipeline, buying audience, competitors, and budget. If AI visibility is part of the brief, we run a PACT audit before the call and present it there.
  2. Scoped proposal We come back within a week with a scope, a target media list, a measurement plan, and a fee.
  3. Messaging and targets The first month sets the key messages, the spokespeople, and the named media targets, so every later pitch draws on one agreed narrative.
  4. Monthly delivery Announcements, pitching, editorial placements, and executive profiling run to an agreed calendar, with monthly reports tracking placements, reach, sentiment, and share of voice.
  5. Quarterly review Each quarter we read the program against the objectives set at the start, and re-audit AI visibility where the engagement includes it.

Which media does Third Hemisphere target from Sydney?

We build every target list from your buyers backwards, and we agree it with you before pitching starts. A Sydney program usually leads with the national business mastheads, because they carry weight with investors and because AI engines cite them, then adds the trade and startup titles that reach your operators and your talent.

For fintech and venture-backed clients, the list concentrates on the reporters covering capital, deals, and technology. For listed companies, it extends to the newswires and the markets desks. Broadcast, podcasts, and international bureaux are added where the story supports them.

  • The Australian Financial Review The masthead investors and boards read first. Our editorial team includes AFR alumni, and our editorial authority programs have turned client executives into regular AFR contributors.
  • The Australian National business and technology coverage with reach into policy and enterprise buyers.
  • The Sydney Morning Herald The city's metro masthead, for stories with consumer, policy, or local business relevance.
  • Capital Brief The subscription briefing read by founders, investors, and operators across Australian tech and capital markets.
  • Startup Daily The startup community's trade title, for funding rounds, launches, and founder profiles.
  • The Age Reached from Sydney for national stories that need Melbourne readership alongside the SMH.
  • Trade and specialist media Fintech, banking, technology, and sector trades chosen for your category, plus the newswires and international bureaux where a story warrants them.

Where is Third Hemisphere's Sydney office?

Level 3, 180 George Street, Sydney NSW 2000, in the middle of the CBD. The agency also has offices in Melbourne and Singapore, and the three work as one team, so a Sydney engagement can draw on all of them.

What does a PR agency in Sydney cost?

Retainers are scoped to your announcement pipeline, target media, and objectives rather than quoted from a rate card. One-off projects, audits, and campaigns are scoped individually. Book a discovery call, tell us what you need to achieve, and we will come back within a week with a scope and a fee.

Which industries does the Sydney team work with most?

Fintech and financial services, technology and deep tech, venture capital and private equity, sustainability and climate, health and life sciences, and professional services. Sydney's concentration of fintech companies and investors means capital markets and funding stories are a daily part of the work.

How quickly can the Sydney team get media coverage?

Most clients see initial coverage within four to six weeks, and a consistent media presence takes three to six months of sustained work. A single strong announcement, such as a funding round or a listing, can land national coverage in its first week when the story and the timing support it.

Does the Sydney team handle AI visibility and GEO work?

Yes. The Fourth Hemisphere: Marketing for AI and the generative engine optimisation service both run from Sydney. We audit what ChatGPT, Claude, Gemini, Copilot, and Perplexity say about you, score it with our PACT methodology, and build the earned media program that changes the answer.

Can the Sydney team support a company expanding overseas?

Yes. Sydney engagements regularly extend into Singapore and South East Asia through our Singapore hub, and into other markets through the campaigns our team runs with international media. One narrative and one measurement framework carry across every market in the program.
