If studying for an exam, a bit expensive but worth a look: Aviation Theory Centre
https://aviationtheory.net.au/shop/p...s-and-air-law/
If wanting more practical stuff for actual flying - the 'VFRG' is pretty much the go to (at least for VFR ops)
Civil Aviation Safety Authority | Visual Flight Rules Guide
(normally you can order hard copies of this but it is out of stock and next edition not available until next year)
