Most published "agency cost in Australia" content states a specific retainer number with no visible sourcing. We'd rather tell you honestly what we do and don't have first-party evidence for — the same discipline we apply to every figure on this site, including our published ad benchmarks, which only ship a number once it's backed by real managed-account data at a minimum sample size, or a clearly-labelled curated third-party source.
What we actually have data on
Our Australian ad-cost data is curated from published third-party sources (rockingweb.com.au, cross-referenced against wordstream.com), not first-party managed-account data the way our Malaysia and Singapore figures are — we don't yet run a large enough Australian book of business to publish first-party AU figures honestly. General cross-industry Google Search CPC runs roughly AUD 2.00–AUD 4.00, with specific verticals (legal, dental) running materially higher; Meta CPM runs AUD 9.63–AUD 21.73, up to a median around AUD 14.38, with finance/insurance regularly exceeding AUD 30; Meta CPC averages around AUD 1.47, up roughly 12% year-on-year as of the source's 2026 report. Vertical-specific figures (aesthetic clinic, dental, interior design CPL) remain verify_gate: true in our own dataset — no sourced AU vertical-specific figure cleared our verification bar this session, so they render as a gap, not a guess.
What we don't have: a retainer-fee range
Agency service retainer fees (as opposed to ad spend itself) aren't covered by any dataset we're confident enough in to publish as a range — the same minimum-account-count discipline that gates every other figure on this site, including our own Hong Kong benchmarks, which are similarly gated for the same reason. We don't have a `benchmarks.json` `au.retainers` group the way Malaysia has `my.retainers`, and won't publish an estimated one.
Directionally: what to expect
Australia's overall digital-advertising market is larger and more mature than Malaysia's or Singapore's, so agency retainers here generally run higher than the Malaysia ranges we do publish — but we don't have a precise first-party multiplier to offer, and would rather say that plainly than present a Malaysia number with a vague "and Australia is a bit more" caveat implying more precision than we actually have.
Fee structures, and the GST question
Australian agencies use the same two models common in Malaysia and Singapore: a flat monthly retainer, or a percentage of ad spend. One Australia-specific check that's easy to miss: confirm whether a quoted fee is GST-inclusive — Australian GST is 10% (ATO), and a quote silent on this can mean a real cost difference on the first invoice. See our guide to choosing an Australian agency for the full evaluation criteria beyond price.
How to evaluate a quote without a published benchmark to check it against
Ask for the fee structure in writing, exactly what's included, and whether it's GST-inclusive. Ask for a real performance number (CPL or CAC) from a comparable Australian account, not Malaysia or Singapore figures presented as if they transfer directly. If a quote feels high relative to figures you've seen from other markets, ask the agency to explain the gap in terms of local talent cost, media cost, or scope — a specific answer is a better sign than a vague one.
