ATIS is valid for an area of 5NM around the aerodrome.
(Looking for a ref...)
If you're outside this (and Maitland is definitely so), no joy.
Serch for remote QNH in ur vols, in NZ its 5ft onto mda for every 1nm over 5nm from QNH Source
Thats us but i cant see it being too different in aus
Ignore this. Australia makes NO allowance for distance outside the ATIS area.
Love answers that have a good potential to confuse the issue by quoting a foreign rule.

You may be getting confused with the preferred altimeter QNH setting when cruising below the transition altitude (10,000'). A known QNH from a source within 100NM is the first choice, followed by area QNH. ENR 1.7 Para 2.1.2 Don't forget area QNH is renewed every 3hrs if you are using it.
