One may be on Helecon paper, the other on ordinary paper. As neither have a clear date, you'll need a UV lamp to check
There are two types of paper, the 1964 Galah was printed on unwatermarked Harrison coated paper (ordinary). And the 1965 Galah was printed on unwatermarked Wiggins Teape coated paper incorporating Helecon. I have all the Helecon types (paper and ink) and all white papers of the pre-decimal QEII era.
ACSC 416: Normal paper - Grey, Pink, Dark Grey and Dull Purple
ACSC 417: Helecon paper - Grey, Dull Pink, Dark Grey, and Deep Dull Purple
The stamps indeed have different ink colours, and the 1965 stamp was printed on whiter paper distinguishing the use of deeper colours on whiter paper.
ACSC 455: 1966. The 15 cent Galah is one of only a few designs from the pre-decimal bird series that survived the transition to decimal currency, the Galah underwent a new design and colours.
The 1/6d Galahs with dates were part of a display I presented to the ACCC in 2018, so I used the display images rather than taking the stamps out of the album.

Hi Rob and Dave
Information is very much appreciated.
Love this forum, I learn something new all the time.
I am putting the many thousands of used pre-decimals into stock at present, and sometimes I notice differences like the galah, because they are so obvious.
One more question for you Rob, With your illustration the different papers show up very well, which is good.
With my example, on the last enlargement, the branches on the tree are more white than your examples, and the wing has a large white patch.
Would this have been caused by ink stripping.

Hi Horamakhet
I do not recall any of the pre-decimal bird series being affected by ink stripping, the whiter part of the wing may have been the result of the stamp being soaked off an envelope and stored.
But there are minor varieties that have a whiter part of the wing.
It could be either one, it is difficult to tell from the scan.

Hi to all,
Now I can not find any listing where this stamp was printed on two different papers, but one of the stamps the tree that the galah is perched in is definitely a different colour
The example on the right, the tree is much lighter, and in the last enlargment, it actually looks like part of the colour is missing on the upper branch as well.
Also the top part of the Galah's wing is missing colour.
I can not find a listing in ACSC QEII latest volume either.
All thoughts appreciated.
Pity it is used.
