AI SDR: what an AI sales development rep does for an Australian sales team

An AI SDR (AI sales development rep) is a voice agent that does the early work of sales development. It calls new leads soon after they come in, follows up leads that have gone quiet, answers inbound calls and books meetings into your team's calendars. It doesn't close deals or replace your salespeople. Its job is to make sure no lead sits untouched and that your people spend their time on the conversations that need them.

For an Australian team, how well an AI SDR works also depends on the rules it runs under. Calling hours, the Do Not Call Register and identification rules decide what it's allowed to do, and they should be written into its setup from the start. Below I cover what the job involves, where people take over, what the agent must never do and how the local rules apply.

What an AI SDR actually does

The label gets used loosely, so here's a working definition. An AI SDR is a voice agent that handles the top of your sales funnel by phone. In practice that covers four jobs.

Calls new leads quickly

When someone fills in a form, requests a quote or books a callback, the AI SDR rings them while they're still thinking about your business. It confirms what they asked about, asks a few qualifying questions you've agreed on and works out the next step. Most teams lose leads in the gap between an enquiry and a reply. The agent's main job is to close that gap.

Follows up quiet leads

Many leads don't answer the first time, and many that do answer go quiet afterwards. Human reps tend to drop these because follow-up is repetitive and easy to put off. An AI SDR can work through a follow-up sequence you've set and try again at sensible times. It stops when the lead responds, books, opts out or reaches the end of the sequence.

Answers inbound calls

Calls that come in after hours or while your team is busy don't have to go to voicemail. The agent can answer, find out what the caller needs, answer common questions from approved information and either book a meeting or pass the call to a person.

Books meetings

The output is a booked conversation with the right person on your team. The agent puts the meeting straight into the right calendar and adds a short summary to your CRM, so the salesperson starts the call already knowing the context.

Where the hand-offs to people sit

How well an AI SDR works depends heavily on its hand-offs. Decide them before you switch it on, and write them down so your team knows what to expect.

Hand-off points to define:

• Qualified and ready to talk: the agent books a meeting with a named rep, or transfers live if someone is available.
• Asks for a person: the agent transfers or arranges a callback straight away, with no arguing.
• Pricing outside your published ranges, custom terms or discounts: these go to a person.
• Complaints, disputes or an upset caller: these go to a manager with a full note of the call.
• Existing customers with service issues: these go to the account owner or support, not into a sales sequence.
• Anything the agent isn't confident about: it says so and arranges for a person to follow up.

For each hand-off, decide who owns it and how fast they respond. An instant AI call followed by a two-day wait for a human undoes the benefit. Look at your CRM views and notifications as well. Reps should see a booked meeting with a summary, not a raw transcript they have to dig through.

What an AI SDR must never do

Guardrails protect your customers and your brand. These belong in your agent's instructions and in your testing:

• Never pretend to be human or deny being an AI when asked.
• Never make promises about price, delivery, results or contract terms that a person hasn't approved.
• Never pressure someone who has said no, or keep pushing after they ask to stop.
• Never ignore an opt-out request. Record it and stop contacting that person.
• Never call outside permitted hours or call numbers you haven't checked against the Do Not Call Register.
• Never give financial, legal, medical or similar advice.
• Never collect payment details or sensitive information over the call unless you've designed and approved that process.
• Never make up an answer. "I'll get someone to confirm that" is always acceptable.

How Australian rules shape what an AI SDR can do

This part gets skipped most often. Remember that an AI voice is treated the same as a human caller for telemarketing purposes. The ACMA states that commercial calls made using an auto-dialler, or that use pre-recorded or AI voices, are all telemarketing calls. The Do Not Call Register Act 2006 also defines a voice call to include a call that involves a recorded or synthetic voice.

Calling hours

Under the Telecommunications (Telemarketing and Research Calls) Industry Standard 2017, unless express consent was given in advance, telemarketing calls must not be made on a weekday before 9 am or after 8 pm, on a Saturday before 9 am or after 5 pm, or on a Sunday.

Those times are measured at the usual residential address of the account holder for the number being called, not where your office is. A Sydney team calling a lead in Perth has to schedule against Perth time. Your AI SDR needs a reliable way to work out the lead's location, and a cautious default when it can't.

Calls outside those times are allowed only if the account holder or their nominee gave express consent in advance to that particular call on that day or at that time, and the caller can show this to the ACMA if required. A general "contact me anytime" on a web form is unlikely to be enough. If a lead books a specific evening callback, store that booking as evidence.

Public holidays

Unless express consent was given in advance, the standard bans telemarketing and research calls at any time on New Year's Day, Australia Day, Good Friday, Easter Monday, Anzac Day, Christmas Day and Boxing Day, and on a weekday holiday given in lieu of one of them. The standard doesn't ban calls on other State or Territory public holidays, but it doesn't exclude State or Territory laws that restrict calling days or times further. Load these dates into your calling calendar, and check with the ACMA or a lawyer about any state-specific rules that apply to you.

The Do Not Call Register

The register works differently from how many people assume. It doesn't block calls. Instead, it lets businesses check their calling lists and remove registered numbers before they call. That checking, called "washing", is your responsibility.

Points that matter for an AI SDR:

• Home numbers, personal mobiles and fax numbers can be registered, but a business phone number cannot.
• A phone used for both business and personal calls can be registered as long as personal use is more than 50% of total use, so a sole trader's mobile may well be on the register.
• Once a number has been registered for 30 days, telemarketers can only call it with the person's consent or if the caller is exempt.
• Registration is free, only needs to be done once and stays in place indefinitely unless the owner removes it, so old lists don't get safer as they age.
• Calling a registered number isn't a breach if you washed your list in the last 30 days and the number wasn't registered at the time.
• Certain organisations may still call registered numbers, including government organisations, registered charities, educational institutions contacting current or former students, registered political parties, members of parliament and election candidates. Most commercial sales teams are not among them.

The practical rule is to wash every list before it reaches the agent and to wash it again on a regular schedule. Leads who enquired themselves are a different situation from cold numbers, but consent needs to be clear and recorded. If you're unsure whether your consent holds up, ask a lawyer.

Identifying itself on the call

As soon as a telemarketing call starts, the standard requires the caller to give their given name (unless the call is made solely using a recorded or synthetic voice), the business name of their employer, the name of the person causing the call to be made, and the purpose of the call. Where a call involves synthetic voices, the caller must also provide a way during the call for the recipient to request contact and complaint-handling details, for example by asking to talk to an operator.

This affects sales outcomes too. The ACCC says the cooling-off period extends to 3 months if the salesperson phones outside the allowed hours, doesn't give their name or the name and address of the business they represent, or doesn't say why they're phoning. Script the agent's opening so it can't skip these steps.

If a provider makes the calls

If a third party runs calls for you, your contract must include express provisions requiring compliance with the Do Not Call Register Act. Read that clause before you sign.

Questions to ask before you switch one on

• How does the agent work out the lead's local time and apply the calling windows and prohibited days?
• Where are list washing and opt-outs handled, and how quickly does an opt-out take effect?
• What does the agent say in its opening, and how does a caller reach a person or get complaint details?
• How is consent for out-of-hours calls recorded and retrieved?
• What exactly triggers each hand-off, and who on our team owns it?
• Can we review call recordings and transcripts, and change the script ourselves?
• What happens when the agent doesn't know the answer?

Where to start

Start small. Point the AI SDR at inbound leads and inbound calls, where consent and context are clearest. Agree on your hand-offs, check the compliance settings against the rules above, then listen to real calls every week and adjust. Once the basics are working, add follow-up of quiet leads.

That's how we built Dialessa: an AI voice sales agent that calls new leads in seconds, follows them up and answers inbound calls, so your team spends its time on the conversations that close.
