All three are safe buys, you're choosing between goods, not avoiding a lemon. Daikin for the biggest service network and all-round polish, Mitsubishi Electric for quiet operation and build quality, Fujitsu to save $300–$600 per room and still sleep fine. The installed-price spread between them matters less than the spread between installers quoting the same unit.
Head to head
| Daikin | Mitsubishi Electric | Fujitsu | |
|---|---|---|---|
| 7kW installed | $3,000–$3,800 | $2,950–$3,750 | $2,500–$3,200 |
| Known for | Service network, dealer program, consistency | Quiet outdoor units, build quality | Value, straightforward reliable units |

| Watch for | Paying the badge premium on rooms that don't need it | Fewer aggressive discounts, prices hold firm | Range spans wider quality band, check the specific series |
Where the real differences live
Service network
The strongest argument for Daikin is boring: more accredited installers and service techs than anyone, everywhere in Australia including regional towns. A decade from now, that's the difference between a $350 repair and "parts are eight weeks away." Mitsubishi Electric is close behind in metro areas; Fujitsu's network is solid but thinner regionally, worth weighing in places like Dubbo where installer supply is already tight.
Noise
Mitsubishi Electric's outdoor units run measurably quiet, which wins strata approvals in apartment suburbs like Bondi and keeps peace on small blocks. If that's your constraint, compare dBA on the specific models quoted, it varies more between models than between these brands.
Price
Fujitsu's case is simply the invoice. Per room, expect $300–$600 under the other two for comparable capacity, real money in a multi-room house ($900–$1,800 across three rooms) for a unit most owners would never pick out of a lineup.

Don't pick a brand and hunt for its cheapest installer, pick two or three acceptable units and make installers compete on the whole job. The same Daikin unit routinely quotes $400+ apart between two licensed installers in the same suburb. Brand choice is a $300 decision dressed up as the main event; the quote comparison is where the real money moves.
