A few comments:
General
- Use 'Present' instead of 'Current'
- Formatting is a bit inconsistent especially with the heading lines
- References should be its own heading. I personally would advise actually having referee names on there (but withhold contact details) to show that you actually do have referees and are not going to search for one in the last minute when they need to be contacted
- I think that the need to condense the resume into 1 page kind of compromises its formatting. It is perfectly fine to have a 2 page resume (which is the norm) unless the employer specifically stipulates that they want a 1 page resume.
Education
- 'major in Accounting/Marketing' sounds like a single major when it should be two majors
- Your '-' in 'Aug 2014 - current' is inconsistent with the other ones later down the resume
- Be a good idea to indicate expected completion of degree (and maybe WAM where applicable)
- You can list your achievements under your degree here
- Given how recently you started your degree, I would suggest putting your HSC as part of your education and the respective achievements you have under your HSC courses
Work experience
- Your duties can be written with a bit of skills-focused language (see Resume section in
http://community.boredofstudies.org...tment-process-part-1-online-applications.html)
- Would avoid using 'I'
- Would put the reception role on top due to reverse chronological order convention (as it is your more 'recent' job)
Achievements and Extracurriculars
- Would put achievements in their respective parts under Education or Work Experience or ECs, not have them in isolation
- Your role name in the Accounting Association is not very clear
- "Strong communicator, with a demonstrated capability to effectively communicate with members." is not really suitable to put there in those exact words as you should be highlighting the duties or achievements which show that you have this trait
- I feel there is a lack of content here as it only mentions two ECs. Surely you have more to show than just those two?
