Deep Research: AU market sizing for my service area

I want to size a market for a specific service in a specific AU geography. Not a global TAM number, an honest local one.

In Gemini, switch to Deep Research.

The service I am sizing: {{service}}
The geography (postcode / LGA / region / state): {{geo}}
The customer I would serve (segment): {{segment}}
Price point assumption: {{price}}
Frequency they would buy: {{frequency}}
Sources I trust most: {{trust_sources}}

Produce a sizing note:

1. **The market in one sentence** - your single best estimate, with a range.
2. **The maths** - explicit assumptions, sources, and the calculation. Show population x penetration x price x frequency, or whichever model fits.
3. **Confidence rating** (low / medium / high) on each assumption, with the source.
4. **What would shrink this market** - 3 factors, each with the influence they have on the final number.
5. **What would grow it** - 3 factors with influence.
6. **The "obviously wrong" check** - what would make this number completely off (e.g. my segment is misdefined, the price is unrealistic).
7. **Sources list** - ABS, council ERP, IBISWorld, ASIC, industry body.

Use ABS where possible. AU English. If a number does not exist, say "no AU data - using NZ proxy at X% discount" rather than inventing one.
