Westpac has staked its strategy on UNITE — collapsing a legacy sprawl of systems and processes into a simpler bank — while its customers still navigate a service estate shaped by that very sprawl: multiple brands, queues and handoffs; an agentic frontline that resolves everyday banking and mortgage-servicing conversations against the simplified core as it lands gives Westpac a customer-visible payoff for a largely invisible transformation, at Australian-labor economics that make every automated resolution count double.
Westpac is one of Australia's big-four banks, operating multiple consumer brands, with the UNITE technology simplification program central to its investor story.
Public factUNITE aims to radically reduce the number of systems, processes and products — a multi-year program consuming much of the bank's change capacity.
Public factMortgage competition and refinancing waves drive intense servicing and retention conversations in Australia's rate environment.
Public factScam-response scrutiny and hardship-handling obligations make emotionally charged, compliance-heavy contacts a growing share of volume.
Reasoned inferenceMulti-brand service estates (Westpac, St.George, Bank of Melbourne, BankSA) likely duplicate service stacks that UNITE will consolidate — a conversation layer can unify customer experience ahead of the plumbing.
Reasoned inferenceBranch closures in regional areas remain politically constrained, shifting structural volume to phone channels.

Technically capable but needs industry workflows, integration, acceleration, or managed operations
Evidence: Westpac has substantial technology capability but its change capacity is publicly committed to UNITE simplification; it adopts platforms with partners for capability adjacent to the core, and banking-grade conversational AI — voice quality, evaluation, delivery at scale — is exactly such an adjacency.
Why they won't build the full stack: Building LLM voice infrastructure mid-UNITE would compete with the bank's own declared priority for engineering capacity; a partnered, governed platform delivers customer-visible results that make the simplification story tangible without burdening it.
Westpac has made the UNITE technology simplification program central to its investor narrative, targeting a materially simpler bank with fewer systems and processes over multiple years.
GTM implication: Sell the conversation layer as UNITE's customer-visible dividend — simplification customers can feel before the core consolidation completes.
Mortgage competition and cost discipline continue to pressure returns across the Australian majors.
GTM implication: Anchor on mortgage-retention coverage and everyday-line cost per contact — the two levers the margin story rewards.
| Workflow | Why it matters here | Value | Complexity | Speed | Channels |
|---|---|---|---|---|---|
Everyday banking and card service line Routine banking resolved in-conversation with one experience across brands; human care for complex and vulnerable customers. | Card, account and payment queries dominate volume across four brands at full Australian labor cost. Friction today: Brand-fragmented queues and IVRs; simple requests wait behind complex cases. | VoiceApp chat | |||
Mortgage servicing and retention desk Servicing questions grounded and resolved; policy-bounded retention with human gates on pricing exceptions. | Refinancing waves make every rate-review call a retention moment with hundreds of thousands of dollars of lifetime value at stake. Friction today: Rate-review and repayment queries queue for specialists; retention offers depend on who answers. | VoiceApp chat | |||
Hardship and scam-response triage Immediate structured intake with protective actions within policy; specialists engaged with full context; every case fully logged. | The most scrutinized contact classes in Australian banking — speed and consistency are conduct outcomes, not just service metrics. Friction today: Distressed customers queue; intake quality varies; documentation burdens compound stress. | VoiceApp chat |
Voice & channel orchestration, telephony, conversational execution, session/state, routing, integration build. Capability coverage validated during implementation.
API access to these systems is the critical-path dependency.
Identity-bound sessions, policy-bounded actions, 100% audit logging, human approvals at defined points, in-tenant intelligence.
All figures are modelling estimates from the labeled inputs above — nothing here is customer-provided yet. The pilot's first job is replacing these assumptions with Westpac's measured baseline. Package price covers implementation only; recurring usage billed separately.
Why this package for Westpac: Everyday banking plus mortgage servicing plus hardship-and-scam triage are multi-workflow Scale scope, sequenced to land with UNITE's consolidation milestones.
Packages cover implementation and integration only. Recurring costs are billed separately: Tilicho Labs platform usage (~$0.15/call-min indicative, usage only), Google Cloud consumption, telephony/carrier charges, managed operations, and support & optimization. No package includes unlimited usage.
“UNITE's risk is being a transformation customers never feel; an agentic frontline that answers instantly across every brand is the customer-visible proof the simpler bank is arriving.”
“A governed conversation layer rides UNITE rather than adding to it — one service experience delivered above the consolidating core, retiring IVR sprawl as systems merge beneath.”
“Change capacity is consumed by UNITE; a bounded frontline deployment delivers service economics now without competing for the program's engineering resources.”
“Refinancing season decides your book; grounded rate-review conversations at full coverage — with pricing exceptions gated to humans — is retention capacity you cannot staff.”
“Hardship and scam playbooks executed consistently with 100% logging turn your most scrutinized contact classes into your best-evidenced ones.”
“UNITE's savings arrive over years; measured cost-per-contact reduction on the everyday lines arrives in a quarter and compounds while the program runs.”

One of Australia's big four, mid-flight through the UNITE technology simplification program — enormous consumer and business contact volume, mortgage-servicing intensity, and a bank whose stated priority is fewer, simpler systems, which a unified conversation layer serves directly.
