She began her career with a win at the African Championships in Athletics in 2006, easily beating the opposition to the 100 m hurdles title.

She faced strong competition at continental level also, as Fatmata Fofanah took the 100 m hurdles title at the 2008 African Championships, leaving Augustus to settle for the silver medal.

She ran at the 2009 World Championships in Athletics, taking part in the hurdles competition as well as the women's 4×100 metres relay race for Nigeria.

The IAAF Doctor's opinion stated that "This finding could be compatible with an administration of testosterone and/or related prohormones…" A series of examinations and tests conducted by an MD specialist in gynecology and reproductive endocrinology at the USC (University of Southern California) Medical Hospital found that Augustus had multiple ovarian cysts which the doctor linked to a disorder called Polycystic Ovary Syndrome or PCOS.

Although the doctor at USC concluded that the PCOS disorder caused the elevated DHEA levels in Augustus’ urine sample, these findings were rejected by the Nigerian committee.
