The Australian multi-brand engagement shape.

By Adam Ducquet · 15 June 2026 · 3 min read

We run several multi-brand engagements at the same time, Gorilla Glue + O'Keeffe's (FMCG), Avant Portfolio (3 sub-brands), Central Innovation (3 brand identities), Partnered Health portfolio (60+ clinics, multiple brands). Same operational shape: per-brand transparent line items, shared infrastructure, one accountable senior strategist.

The shape

One retainer relationship with the parent group / portfolio CEO. Per-brand transparent line items on every Xero invoice. Shared infrastructure underneath (BigQuery + Looker reporting layer, AHPRA / compliance pipelines, Block Hours pool, AI-augmented production stack). One senior strategist as the engagement-anchor across all brands in the portfolio.

Why this beats single-brand engagements multiplied

1. Strategic coherence across brands

One senior strategist seeing all the brands' performance side-by-side surfaces cross-brand patterns that per-brand strategists miss. Insights from one brand's seasonal cycle inform another brand's seasonal cycle. Creative learnings cross-pollinate. The strategy isn't a function of N parallel feedback loops, it's one feedback loop with N distinct outputs.

2. Shared overhead pool

The Block Hours pool flexes between brands as needed. When Gorilla Glue runs a campaign launch, hours flow there; when O'Keeffe's needs a homepage refresh, same pool. Each brand benefits from a larger effective creative team than they could justify standalone.

3. Agency-side senior commitment

Multi-brand engagements deserve senior-strategist time. Single-brand engagements at smaller revenue tiers can't always justify it. Multi-brand at portfolio-level revenue does. We staff multi-brand engagements with the senior bench because the integrated value justifies it.

4. PE / parent finance reconciles cleanly

Per-brand invoicing means PE finance + parent finance can reconcile against budget at brand level. The Gorilla Glue + O'Keeffe's invoice has explicit lines: "Webhosting & Maintenance Fee (gorillaglue.com.au)", "Webhosting & Maintenance Fee (okeeffes.com.au)", "Digital Agency Fee (Gorilla Glue)", "Digital Agency Fee (O'Keeffe's)". No shared overhead allocations, no creative accounting.

Where this engagement shape fits

  • FMCG groups with 2-5 Australian brand identities under one parent (Gorilla Glue + O'Keeffe's pattern)
  • PE-backed multi-clinic healthcare portfolios with multiple brand identities (Partnered Health pattern, scaled to 60+ clinics)
  • B2B professional services portfolios with related sub-brands (Avant Portfolio pattern, Practice Solutions + Finance + Insurance)
  • Industrial firms with sub-brand vertical specialisms (Central Innovation pattern, parent + AEC sub + MFG sub)
