What a fractional CTO costs in Australia, plainly.

Every fractional CTO page says the same three things and almost none of them say a price. So here are the ranges as they actually sit in the Australian market in 2026, and then the more useful part: how each pricing model behaves once you are inside it.

The three models you will be quoted

Day rate

Between 1,500 and 3,000 dollars a day for someone genuinely senior, usually sold as one or two days a week. So 6,000 to 24,000 dollars a month depending on how many days you buy.

The problem with day rates is structural. You are paying for attendance, so the incentive runs towards more days rather than fewer problems. It also means the meter is running every time you ask a quick question, which is exactly the moment you most want to ask.

Hourly

Between 250 and 500 dollars an hour. Fine for a one-off opinion, poor for anything ongoing. Nobody sends the awkward two-line question to someone billing in six-minute increments, and the awkward two-line questions are where the money is saved.

Monthly subscription

A flat fee, commonly 4,000 to 12,000 dollars a month, for unlimited requests handled one at a time. No timesheets. You send what you need, it gets worked through in order, and the invoice does not move.

This is the model we sell, so treat that as disclosed bias. The reason for it is simple: it removes the hesitation. Clients who are not counting hours ask earlier, and problems asked about earlier are cheaper to fix.

What moves the price

• Actual seniority. Someone who has run a team of fifty and carried a profit and loss prices differently from someone who was a lead developer last year. Both call themselves fractional CTOs.
• Scope. Advising on a roadmap is not the same as owning delivery, managing an agency and sitting in board meetings.
• Responsiveness. A guaranteed turnaround costs more than best effort, and is worth more when something is on fire.
• Team size. Five engineers to oversee is a different job from twenty-five.
• Stage. Pre-product work is judgement-heavy and fast. Post-revenue work carries risk, compliance and customer commitments.

Fixed-scope work, priced separately

Two pieces of work are usually quoted on their own rather than folded into a retainer, because they have an end:

• A technical audit or due diligence review, commonly 4,500 to 15,000 dollars depending on the size of the estate. What that review covers.
• An MVP or first product build, commonly 25,000 dollars and up. What drives that number.

Questions to ask before you sign

1. 1What is the turnaround on a normal request, and what happens when it slips?
2. 2How many other clients are you carrying right now?
3. 3What is the notice period, and is there a lock-in term?
4. 4Who does the work if you are unavailable for a fortnight?
5. 5What is explicitly not included, so that I know where the extra invoices come from?
6. 6Can I speak to a client who stopped working with you?

The last one separates the market. Anyone doing this properly has clients who finished, usually because they grew into a full-time hire, and is happy for you to hear about it.

A note on cheap

Under about 3,000 dollars a month you are buying a few hours of somebody who is stretched across too many clients. That is not automatically bad value, but be clear about what it is: an advisor you can ask questions of, not a leader who will own outcomes. The gap shows up on the week something breaks.
