Didn't look at the word doc you've uploaded, so this mightn't apply.
In my opinino you need a little more... um.. something. I had a good website for cover letters... from memory I typed in "cover letter style" into google, or maybe even just "cover letter"... Regardless, there's some basic structure: First paragrpah: that you're applying, where you saw the ad, what date the ad was advertised on. Second & Third paragraph: who you are, why you'd be right for the job.
I don't know about telling him you'll contact him in the week: not doubting it, just I don't know whether that's convention. If I were reading that I'd see you as enthusiastic, but I'd prefer to contact
you, rather than the other way around. Definetly don't hesitate in contacting them, but I'm not sure if it needs to be said.
Don't use "I hold a lot of interest" (second paragraph) -- to me the wording seems rather simple. Something like "I am interested in..." does the same thing, flows better and sounds a little less awkward. Don't mention the specific magazines you read -- first off, you're inviting troubles (what if this guy doesn't have a high opinion of either, and even if he does, what if he thinks you should be looking for more?), and beyond that it seems too explicit. Just indicate you take an active interest in the current news and trends of the business world. (On that note, there's a newsletter you can subscribe to at cpaaustralia.com.au.. don't knwo if it's any good: I delete it every week becuase I got conned into subscribing, and haven't gotten round to unsubscribing, but I've got no interest in accounting.. might be another news source for you, which is a little more accounting-specific, and directed at students... (I think?!))
specify the degree you're doing, esp if you're majoring in accounting, or it is an accounting degree, and Link it and your education to the job more. Make the fact you're doing a uni degree a little more intertwined with the reason YOU'RE the one for the job. Start with general business-related stuff, and then hone in on the accounting..
I am currently in my Xth year of studying a XXXXDegree, majoring in XXXX, (or, if you don't know what yu're majoring in, say "condsidering a major in XXX"), and have found the knowledge I have gained to be very interesting and engaging. I have found Accounting to my taste, and am enthusiastic to gain a practical understanding of this field to complement my education.
I like your last line -- it's confident in that you're telling them that you can do it from them, but it should be a closing paragraph. Make it two long sentences, or something.
I know that the combination of my experience, education, and motivation to excel will make me an asset to your Accounting department, and if you're looking for a interested (don't like the word interested, but something to that tune) and dedicated individual to fill this position, who is enthusiastic to learn and develop himself in this field, please take a moment to consider my application.
(that sentence is in two halves... broken at "and if you're looking for...".. the first half of the sentence could be put at the end if you prefered it that way.
Finally, keep in mind that some people read the cover letter first, and then the resume, and other people do it the other way round. You want to sell yourself just as well in both of them, or you'll risk hitting someone who does it the reverse way you expect, and they think you're just another average joe. I'd also try and get some of your existing experience in, even if it's just retail or something, and link it in: retail helps you talk, office work helps you be organised, supermarkets teach you discipline and inspire you to greater things (lol)... etc...
Hope that helps a little!
. Also, don't really use colours in your resume either. It's better if its just text based. If you want to use colours then make sure it looks very professional then
