Market comparison
Australia vs Ireland: agency markets compared
Digital demand is still growing while total agency bookings are not, so agencies compete harder for retained work. Search and social capability is deep and competitively priced, while senior brand strategy concentrates in a smaller number of groups.
Market size and coverage
Advertising figures come from the named industry body or statistics agency in each market. They are published on different bases and in different currencies, so treat them as scale, not a ratio.

Choosing between Australia and Ireland
- Pick the market where the work is being sold, not where it is cheapest. Local media buying, language and consumer regulation are the hardest things to outsource across a border.
- For a cross-border engagement, agree the contract currency, who carries exchange-rate risk, where the work is performed and how personal data moves between the two jurisdictions before you sign.
- Ask both shortlists the same question: show one comparable project, the brief, what changed afterwards, and where those numbers came from.
- Check who actually runs the account. In both markets, the senior people in the pitch are frequently not the people delivering the work.
