Some tips about personal details information:

• It isn’t usually necessary to provide details of your age or marital status.
• If you have a non-Anglo name you might want to consider including a sub heading like “Residency Status:” and then indicate Australian citizen, or Australian Permanent Resident.
• Have a professional sounding email address. Email addresses such as hotchick@abc.com or stanthestud@abc.com will not do much to enhance your professional image.
• Review your voice message so that you sound professional. For example, a curt or bored “Hi, leave a message” or perhaps some sort of wacky greeting will also have a poor impact on your image.
