A note to John Gowings · Gowings Bros · The pack, with the synthesis at its centre

AI Datacentres

A working investor pack on AI data centres in Australia, organised around a single recommended position. The synthesis names the build. Six further pages size it, cost it, test it, and place it inside the global picture.

I · The recommendation

Synthesis

Build a Sydney-metro boutique standalone at twenty-two to twenty-eight megawatts. The frontier refusal stands; this recommendation is what was inside it.

II · The boutique, sized

Footprint

Seven premium-local segments populate the boutique tier. A demand stack across five years against a capacity line that steps once. The shape supports the build.

III · Where the money goes

Cost stack

The line-by-line accounting beneath the underwriting. AUD 1.26B of one-time capex, AUD 33M of annual opex, AUD 180M of thirty-year refresh, with the Australian premia surfaced at the lines they bite.

VI · Supply side

Compute

An AI data centre, from chip to hall, at four scales of magnification. The chip does the work; everything else exists to keep it cool, fed, and connected.

VII · Demand side

Demand

What the customer is actually buying when they buy compute. The middle of the data flow is the only thing billed; what goes in and what comes back is the customer's own.

How to read

Start with the synthesis. It names the position and shows live what the build pays at conservative inputs. From there: the footprint sizes the seven segments and the five-year demand stack; the cost stack decomposes every line; the underwriting calculator stress-tests at the corner cases.

The thesis dashboard places the capital inside the global four-thesis frame. Compute and Demand are scale-agnostic visual notes that orient the reader to the asset itself.
