In 2011, Geitz played a major role for the Queensland Firebirds to not only win the ANZ Championship undefeated. In addition, Geitz was part of the Diamonds squad for the 2011 Netball World Championships in Singapore. Although Geitz did not play as Goal Keeper in the first half (Susan Fuhrmann played Goal Keeper for the first half) against New Zealand, her impact helped recover a six goal deficit to force the match into overtime. This move proved to be successful as Diamonds prevailed their rivals to a one goal victory.
Geitz won the honour of the Liz Ellis Diamonds Award in 2011. She has earned herself 32 Test Caps for Australia.
In 2013 she led the Australian team for the first time, winning the Constellation Cup against New Zealand.
