How a Sydney agent got 141 vendor leads in 90 days

Leonardo Garcia-Curtis04/05/2026
TL;DR

Shannon runs a boutique real estate agency in mid-market Sydney. She was paying over $1,500 AUD a month for two overseas telemarketers who didn't know the suburbs, the schools, or the strata politics.

In January 2026 she swapped them for a Waboom AI voice agent. By the end of March the agent had dialled almost 10,000 phones, had 1,997 real conversations (≥30s), and live-transferred 141 interested sellers to Shannon. That's 7.1% of every real conversation turning into a warm vendor lead.

Total spend: $4,617 NZD over 90 days. Cost per warm-transferred seller: $32.74. Her portfolio is filling up.

How a Sydney agent got 141 vendor leads in 90 days

Meet Shannon. She runs a boutique real estate agency in a mid-market pocket of Sydney where the average sale sits between $1.2m and $2m. The kind of suburb where the agent who knows the street, the schools, and the strata politics gets the listing.

For the last 18 months, Shannon's prospecting was outsourced to two overseas telemarketers. Over $1,500 AUD a month, every month. The vendors hung up a lot.

In January 2026 she switched.

Marrickville. Drummoyne. Five Dock. Streets that aren't making the front page of the property pages, but where Shannon's vendors live. Houses that look something like this. Federation brick. Sandstone footings. A frangipani out front older than the current owners.

Vendors here have specific questions. What is the ICSEA at the local primary? How long is the bus to Wynyard at 8am in peak traffic? Has the strata finalised the cladding works? What did the comparable terrace on the next street go for last month?

The agent who can answer those questions wins the listing. Two telemarketers reading from a generic script couldn't.

The Funnel

What 10,000 dialled phones produced

8 campaigns ran from January through March. Just under 10,000 distinct phones dialled. 10,713 total dial attempts (1.08 per phone, no aggressive retry pattern, one ring then move on).

Of those 10,713 calls:

Outcome Count % of all calls
Any human pickup 3,609 33.7%
↳ Real conversation (≥30s) 1,997 18.6%
↳ Very short connect (<30s, hung up) 1,612 15.0%
Voicemail 3,618 33.8%
Rang out / dead line 3,486 32.5%

The bit that mattered: the 1,997 real conversations. Anything under 30 seconds is usually someone who hung up before the agent got a chance, even on a witty agent that breaks the ice fast and slips the key qualifying question in early ("are you looking to buy or sell your property?"). Anything that hits voicemail doesn't get a script played at it. The platform only counts the calls where a human and the agent actually had a back-and-forth long enough to learn something.

The Sellers

The 141 sellers (and what 7.1% means)

Of those 1,997 real conversations, the agent identified 141 prospects who were genuinely thinking about selling, qualified them, and live-transferred them to Shannon while still on the line.

7.1% of every real conversation turned into a warm vendor lead. That's the headline number for any prospecting outbound: when an actual human gets on the call, how often does the agent get them across the line into the agent's queue? In Shannon's data, roughly 1 in 14.

Another 26 prospects asked Shannon to call them back personally. 26 more asked for a six-month check-in (a tag the platform queues automatically into the next quarterly campaign, so the warm pipeline keeps compounding).

Outcome Count % of real conversations
Live transferred to Shannon 141 7.1%
Asked Shannon to call back 26 1.3%
Asked for 6-month callback 26 1.3%
ANY interest signal 193 9.7%
Roughly 1 in 10 real conversations produced an interest signal Shannon could action. 193 future touchpoints from a single quarter of automated dialling.

The Spend

What it cost

50+ hours of real conversation

In 90 days, the agent racked up 50.9 hours of pure talk time with potential vendors. Just the conversations. Not the dial time, not the voicemails, not the dead lines underneath. To produce that talk volume manually, Shannon would be on the phone for hours every working day, never mind all the dialling it takes to get those conversations to happen. The agent does it in the background while she lists houses.

  • Total spend across all 8 campaigns$4,617.03 NZD
  • Total talk time50.9 hours (3,054 min)
  • Average cost per call$0.43
  • Average cost per real conversation$2.31
  • Cost per warm-transferred seller$32.74

$32.74 to put a qualified vendor in front of Shannon, on the phone, ready to talk. $23.92 if you widen the lens to any interest signal (warm transfer plus callback request plus 6-month re-engagement).

For comparison: Shannon was paying her two overseas telemarketers more than $1,500 AUD per month, every month. Roughly the same in NZD as the AI agent has cost across the entire 3-month window. With far fewer dials, far fewer leads, and zero ability to follow up at midnight on a Wednesday.

Why The Switch

Why offshore stopped working

Two reasons.

Context the agent has, that the telemarketers didn't. The AI voice agent is loaded on Shannon's patch. Not just the suburb names. The ICSEA scores for every primary and high school in the catchment, pulled straight from My School. Bus and ferry timetables to the CBD at 8am peak. Strata histories for the buildings that have been through cladding remediation. Comparable sales on the next street going back two years. The Aussie vernacular that signals to a vendor that the person on the line is local: granny flat, knock-down rebuild, torrens versus strata, kerbside chats, off-market.

When a vendor says "we are looking at maybe selling once strata sorts the cladding", the agent knows what cladding remediation means for this building cycle and what it does to a vendor's timing. When they say "the bus is a nightmare from here", the agent knows whether they're right or whether the new metro changed it.

That's the layer two telemarketers reading from a generic script in another country don't have. Not because they aren't competent. Because nobody hands a contract worker overseas the My School ICSEA scores for inner west Sydney before each shift.

Volume and consistency. Almost 10,000 dials in 90 days is what 2 telemarketers might manage in 4 to 5 months at full pace. No holidays. No sick days. No quality drop in the back half of each shift. The agent is on at 7am. The agent is on at 7pm. It doesn't get rude when prospects are rude. It doesn't stop dialling because Friday afternoon hit.

Honest Framing

The honest math (and the caveats)

Three caveats so nobody buys with the wrong expectation.

It isn't a salesperson replacement. The 141 warm transfers all needed Shannon on the phone next, doing the human work of building rapport and securing the appraisal. The agent gets the vendor across the line into a live conversation. Closing the listing is still hers.
It isn't magic. List quality matters. The system slows down and re-paces when a list is producing low-quality conversations. Garbage in still hurts.
Bookings happen off-platform. Most of the 141 warm transfers turn into appraisal meetings later, in Shannon's calendar, not in the dialer. So the warm-transfer count is the metric that matters here, not in-platform meeting bookings.

The Pipeline

141 vendor leads is a waterfall, not a wall

Shannon isn't listing 141 houses next month. That's not how this works.

What 141 means for her business: a multi-year waterfall of warm vendors at different stages of selling. Some are listing in 6 weeks. Some in 6 months. Some in 18 months once strata sorts the cladding or the kids finish at the local primary. The agent flagged all 141 as serious enough to talk to and warm enough to transfer to Shannon live. She now owns the relationship.

Meanwhile the rest of the database keeps growing. Shannon adds new contacts from her own social media posts, auction sign-ins, open home walk-ins. Every 90 days the agent re-runs the campaign on the full database, the new additions and the original 141.

Here's where it compounds. The agent doesn't call the 141 again from a fresh script. It opens with the context from the last conversation: "Hi, last time we spoke you mentioned you were waiting on the strata cladding works to wrap before listing. I wanted to check where that landed."

That opener doesn't happen with two telemarketers in another country reading from a fresh template every quarter. It's the difference between a one-off campaign and a pipeline that compounds.

Where Shannon is now

90 days in, the agent is on its 9th campaign. She has stopped paying offshore. Her CPA on warm vendor transfers is sitting in the low $30s. The portfolio is filling.

If you're running a boutique real estate practice in NZ or Australia and you're paying for prospecting that doesn't understand your market, the maths above are now a known quantity rather than a guess.
