Given D7's relatively short turnarounds, would they even shut systems like that down?

What would happen if the ADIRU's were turned off by accident on take off? Could this have led to the left hand turn (if the pilots weren't all that familiar with YSSY)?

Lots or stuff would've , or wouldn't have, happened.
They do a lot of things. More than an IRS on a 744 or 737.

Here's a link to the wiki stuff

The Airbus FCOM calls for the IRU's to be re-aligned on a crew change. Even if it's just a straight handover, you still re-align the IRU's. Especially given the length of the flight they'd be carrying out.

The only way you can turn off the ADIRU's is to physically reach up above the Captain and pull and turn them. So during a take off, that's virtually impossible unless absolutely entirely intentional.

A Captain told me a story about an event that occurred to a 747 operator at Sydney years ago, where the Captain decided to try and re-align the IRS's at the end of the runway just prior to take off to fix a problem. However they were told to line up straight away, which they did, and took off. Not a good result in the end, which required a return to land.

All sorts of things could have possibly happened or gone unserviceable. More likely to have gone unserviceable.

A difference of I think it's greater than 5 degree's between nav displays, will trigger an ECAM.

ATSB is investigating it.
