1. Licence and medical certificate, check. ...But where does it say I need photographic ID in the regulations?
Take a look at the new Part 61 eg 61.340. My current licence has my pic on it - the FAA accepted it as a photo ID to carry with me their regs (was told this when I got my USA licence re-validated recently).
No current requirement per the regs but an excellent idea regardless.
Weather and notams, check, downloaded from naips either printed or electronic on my phone or iPad
No requirement to carry a copy.
Appropriate current charts and documents?
Seems like an appropriate item - much better than the very prescriptive and onerous draft Part 91 that I recall.
Are you using an EFB? Too bloody right! Ozrunways! But what are these "considerations" of which you speak???
Read the CAAP and understand what requirements apply to you.
Flight manual up to date. How the *&^% would I know? It comes with the aircraft.
If you are not the owner or operator then just check that the aeroplane has an AFM (if it is required for that aircraft).
Evidence of weights, check. I do weight and balance ....
No requirement to carry W&B data with you.
