[1] After a successful year playing in the Commonwealth Bank Trophy premiership-winning team in 2001, national selectors identified Hornibrook's talent and she received her first invitation to join the Australian squad in 2002.

However it was not until early 2005 that she received her first call up to the Australian open team, making her debut in a match against England, which Australia won by 40 goals.

One of netball's most consistent players, Hornibrook is noted for her speed and persistence, being nicknamed "the rash" by some opponents.

She has been an integral member of the Sydney Swifts national league team since 2000, and has played a key role in their four premierships (2001, 2004, 2006 and 2007).

A versatile player and natural athlete, she forms a formidable combination with fellow Australian representatives Liz Ellis and Mo'onia Gerrard, and rarely puts in a poor performance.
