1. Well-written:
	1a. the prose is clear, concise, and understandable to an appropriately broad audience; spelling and grammar are correct.	Grammar error in first para of Taxonomy and Evolution. Text should read "different from" or "different to" not "different than" which makes no sense. "Than" is used for comparative adjectives (eg. "bigger," "happier," "faster" or even "more different")
	1b. it complies with the Manual of Style guidelines for lead sections, layout, words to watch, fiction, and list incorporation.	Lead: ok; Layout: ok; weasel: ok; fiction: n/a; lists: n/a
2. Verifiable with no original research:
	2a. it contains a list of all references (sources of information), presented in accordance with the layout style guideline.	OK
	2b. reliable sources are cited inline. All content that could reasonably be challenged, except for plot summaries and that which summarizes cited content elsewhere in the article, must be cited no later than the end of the paragraph (or line if the content is not in prose).	"The koala's small brain size is possibly due to the lack of sufficient energy to sustain a larger brain." needs to be cited. Cite 31 is the citation. All the information in the article is sourcedto the very next cite. I've learned it is redundant to cite the same thing twice in a row. LittleJerry (talk) 17:17, 5 April 2013 (UTC)[reply] Hm. The "next cite" is actually 32. Could you please cite the sentence with 31 or 32 as appropriate - this actually illustrates the reason: things quickly move about or get separated by editing, often by many hands, that's just how it is. Done. LittleJerry (talk) 17:44, 5 April 2013 (UTC)[reply]
	2c. it contains no original research.	OK
3. Broad in its coverage:
	3a. it addresses the main aspects of the topic.	Taxonomy and evolution section is very brief. Could there be a cladogram or other diagram of the place of the current Koala among the fossil species? There could be a timeline or set of (overlapping) horizontal bars, for instance, to show when the other Koalas lived (and went extinct). The relationships with marsupial tapirs etc, and the possums and kangaroos would be much easier to visualize with a simple cladogram (could have just one branch for all the Koalas). - I'll check and see if the papers have have contain phylogenies but I don't know how to do a cladgram. LittleJerry (talk) 17:30, 5 April 2013 (UTC)[reply] Either clarify the text or add a diagram such as a timeline. Clarify what? It states that the koala branch was the earliest to branches, I don't think we need to get into detail on the branches of the other families. LittleJerry (talk) 18:16, 5 April 2013 (UTC)[reply] Article should discuss the distinctly inedible diet - see e.g. Moore B, Foley WJ. Tree use by koalas in a chemically complex landscape]. Nature 2005;435:488-490. And why are Koalas so apparently defenceless themselves - often, such slow "prey" are aposematic - dangerous or poisonous? Perhaps the literature discusses this. It is discussed in the "description" section. ~~As for defences, the literature I have does not seem to discuss this, but I'll look further.~~ LittleJerry (talk) 17:27, 5 April 2013 (UTC)[reply] Description doesn't address the question. I added that koala have few predators and birds of prey are threats only to the young. LittleJerry (talk) 18:16, 5 April 2013 (UTC)[reply] This works better.
	3b. it stays focused on the topic without going into unnecessary detail (see summary style).	Not sure the list of people photographed with koalas is really relevant, and it's almost uncited. Perhaps the whole "Cultural significance" section needs gentle pruning and attention to being "encyclopedic". I removed Jackie Chan and Janet Jackson but left the others. It is notable that so many powerful leaders have their pictures taken with the animal and it illustrates its international appeal. LittleJerry (talk) 17:40, 5 April 2013 (UTC)[reply] Thanks.
	4. Neutral: it represents viewpoints fairly and without editorial bias, giving due weight to each.	OK
	5. Stable: it does not change significantly from day to day because of an ongoing edit war or content dispute.	No sign of recent editwarring.
6. Illustrated, if possible, by media such as images, video, or audio:
	6a. media are tagged with their copyright statuses, and valid non-free use rationales are provided for non-free content.	Not sure if Platinum Koala is validly licensed. Replaced. LittleJerry (talk) 17:27, 5 April 2013 (UTC)[reply] Thanks, that's better.
	6b. media are relevant to the topic, and have suitable captions.	Seem to be too many images of Koala "portrait", "On Kangaroo Island", "Resting" -- are these images adding anything to the article? Yes, the Kangaroo Island picture is next to the paragraph that talks about invasive populations and the "portrait" give the reader a good view of the animal when reading the description section. LittleJerry (talk) 17:27, 5 April 2013 (UTC)[reply] The main thing the Kangaroo Island picture adds is the caption, otherwise it's just a Koala in a tree; same for Portrait. I think "portrait" should go, it's redundant with the lead image, which does the same thing better. Did some replacing and rearranging. LittleJerry (talk) 18:45, 5 April 2013 (UTC)[reply] I wonder if it would be helpful to include an image of e.g. Eucalyptus tereticornis to show a major food plant? Already have one of the animal eating. LittleJerry (talk) 17:31, 5 April 2013 (UTC)[reply] I saw. But since the Eucalyptuses are so important it could be good to show the food plant more clearly. I don't think theres enough room. LittleJerry (talk) 18:17, 5 April 2013 (UTC)[reply] It's linked, I guess - seemed there was room for multiple images... but it does look and read better, and I think the GA threshold has been reached. Picture of 'Koala Rock Art' isn't actually of a koala. It is the lighting man painting at Norlangie Rock in Kakadu, Northern Territory (see below link). http://www.google.com.au/search?bav=on.2,or.r_qf.&bih=853&safe=active&q=Lighting+man+kakadu&bvm=bv.48705608,d.aGc&biw=1680&wrapid=tlif137386711625110&um=1&ie=UTF-8&hl=en&tbm=isch&source=og&sa=N&tab=wi&ei=64zjUfHtLITziAfhxoDIDA Concerns verified - the photo has now been replaced - see discussion Talk:Koala#Questionable rock art image - File:Koala_rupestre.jpg.

	7. Overall assessment.	A readable and informative article on a popular topic.
