AI Cold Calling Tradies Australia: How Amy Books Leads at $0.07 a Call
Australian tradies — plumbers, electricians, painters — answer their phones at 40–60% rates because every unknown number could be a job. That makes them one of the best audiences for AI cold calling. Here's exactly how Amy, the AI caller I built for this market, works: the script, the timing, the phone setup, and the real numbers.
The Problem Amy Solves
Most Australian tradespeople run their business from their phone. They book jobs, order materials, and manage customers all by text and call. But they have no time to do outbound sales — they're on the tools all day. If they want more work, they rely on word of mouth and hope. Amy solves the outbound problem by calling prospects while the tradie is on the job.
Why Tradies Are Ideal for AI Cold Calling
There are three reasons the tradie market works so well for AI cold calling, and none of them are obvious until you've run the campaigns:
- They answer unknown numbers. A tradie running a painting or plumbing business sees an unknown AU number and thinks: potential job. Answer rate on our AU campaigns runs 40–60% — double the US B2B average.
- Their pain is concrete. Missed calls, slow periods, relying on seasonal referrals. Amy's offer — a free demo website to generate more leads — hits a real and immediate need.
- The decision maker is the caller. No procurement committee. The plumber who picks up is also the person who decides. If they like the offer, they book. Same-call conversion is possible.
How Amy Works: The Full Call Flow
List preparation
Scraped from Yellow Pages, Google Maps, and tradie directory sites. Filtered by trade category, postcode, and whether the business has fewer than 5 reviews (signal of limited online presence — the exact pain point Amy's offer addresses).
DNC scrub
Every number is checked against the ACMA Do Not Call Register before dialling. ABN-registered businesses have more flexibility than residential numbers, but we scrub both lists.
Amy dials at 7 AM Sydney time
VAPI triggers the outbound call from the AU number (
The conversation
Amy introduces herself, states the offer in one sentence, handles the most common objection, and asks for a 15-minute screen share. If yes, she sends a Calendly SMS immediately.
CRM logging
Call outcome, duration, and transcript are written to a Google Sheet automatically via VAPI webhooks. Hot leads get a follow-up SMS within 2 hours.
The Script (Amy's Opening — Script A)
This is the actual opening script Amy uses on cold contacts. It's been through four iterations. This version performs best:
What's doing the work here:
- "I'll be upfront — this is an automated call" — reduces hang-ups by ~20% in testing. Acknowledging the obvious beats pretending.
- "free demo website" — tangible offer. Not "a conversation" or "to learn more about your needs."
- "15 minutes" — low friction ask. Not a sales call. Not a demo. A look.
- No price mention. Price comes on the screen share, not the cold call.
Getting the AU Phone Number Right
This is where most people trip up when setting up AU AI calling from outside Australia.
You need a real Australian phone number — not a VoIP number that shows an international prefix. Tradies see a +1 or +44 prefix and hang up immediately. The answer rate difference between a +61 number and a US number is massive: ~50% vs ~8% in our data.
The setup:
- Twilio AU number: Purchase a +61 mobile or local number via Twilio. Costs ~$2–5 AUD/month.
- VAPI phone number configuration: Link the Twilio number to your VAPI assistant via the VAPI dashboard or API.
- Carrier registration: For high-volume calling (100+ calls/day), Twilio may require business verification. Do this before you need it.
Best Call Times for Australian Tradies
Lunchtime (12–1 PM local) is the secondary window. Avoid afternoons — tradies are on-site finishing jobs and won't engage. Never call after 5 PM.
Setup Checklist: What You Need to Run This
- VAPI account — create at vapi.ai. Start on the pay-as-you-go plan.
- ElevenLabs account — for the voice. The Matilda voice works well for AU audiences. Clone a voice if you want something more specific.
- Twilio AU phone number — a +61 mobile or geographic number. ~$2–5 AUD/month.
- Lead list — scraped or purchased. Trade, postcode, phone. Minimum 500 contacts to get meaningful data.
- DNC scrub — check every number against the ACMA DNC Register. It's free to query.
- VAPI assistant config — system prompt, voice, STT (Deepgram Nova-2), endpointing settings, webhook URL for CRM logging.
- Calendly link — sent via SMS post-call for booked leads.
- Google Sheet CRM — or equivalent. Log every call outcome, transcript, and callback schedule.
Compliance in Australia
ACMA's telemarketing rules apply to all calls made to Australian numbers, regardless of where the caller is located:
- Register your campaign against the DNC register. Residential and mobile numbers require DNC scrubbing; business lines have more flexibility but it's still best practice to scrub.
- Calls can only be made between 9 AM – 8 PM on weekdays, 9 AM – 5 PM Saturdays. No calls on Sundays or public holidays. Amy calls at 7 AM — technically outside these hours for residential. For business mobile numbers used primarily for work, this is a grey area. Get legal advice if volume is high.
- You must identify the caller (person or company on whose behalf the call is made) within the first few seconds.
- Automated messages left on voicemail have separate rules under the Spam Act — don't leave automated voicemails without reviewing this.
When This Doesn't Apply
- Your tradie target is already overwhelmed with work. If the local plumbing market has a 3-week wait, pitching more leads won't land. Amy works best in markets with moderate competition or seasonal slowdowns.
- You're targeting residential numbers, not business mobiles. ACMA compliance for residential is stricter, DNC rates are higher, and the conversion rate is significantly lower. Stick to ABN-registered businesses.
- You're calling without a real AU number. Don't bother. The answer rate drop from an international number makes the campaign uneconomical.
- You have no follow-up process for booked leads. Amy books the screen share. A human needs to show up for it. If there's no one to close, the booked meetings are worthless.
FAQ
Can AI cold calling work for tradies in Australia?
Yes. Tradies answer unknown numbers at 40–60% rates because every call could be a job enquiry. The key is calling at the right time (7–9 AM local) with a concrete offer (free demo site, not "a chat") and an AU phone number, not an international one.
What is the best time to cold call Australian tradies?
7–9 AM local time. They're driving to their first job and answer the phone. Lunchtime (12–1 PM) is secondary. After 4 PM the answer rate drops sharply — they're wrapping up jobs and don't want sales calls.
Is AI cold calling legal in Australia?
Yes. ACMA governs telemarketing. You must scrub lists against the Do Not Call Register before dialling. ABN-registered business numbers have more flexibility than residential. Automated calls must identify the organisation within the first few seconds.
How many bookings from 75 calls per day?
Based on Amy's production data: 30–45 answered calls from 75 dialled, with 1 in 20 converting to a booked screen share. That's 1–2 meetings per day costing $5.25 total in AI infrastructure.
What phone number do I need to call Australian tradies?
A real +61 Australian number, provisioned through Twilio. International numbers get ~8% answer rates vs ~50% for AU numbers. This isn't optional — it's the single biggest factor in whether the campaign is economical.
