Tuhia he haere tonu mo tenei whitianga - I te tau 2007, kei runga ia i te roopu Tiamana U17 i toa i te 2009 UEFA Women's Under-17 Championship. I te kapa U19 o Tiamana i te tau 2010, i uru a Benkarth ki te 2010 UEFA Women's Under-19 Championship i Maketonia. I tae te kapa ki te haurua whakamutunga, engari i hinga, mo te toa o muri mai, France i nga whiu (5<unk>3). I taua tau ano ko ia tetahi o nga roopu motu i toa i te 2010 FIFA U-20 Women's World Cup
i roto i to ratou ake whenua, i noho hei kaitiaki tuatoru i muri o Almuth Schult me Desirée Schumann kaore i purei i tetahi whakataetae. I te 2012 FIFA U-20 Women's World Cup i Japan i purei ia ia meneti i nga tukinga e ono, i purei a Tiamana i te whakataetae kaore i whiua he whaainga kotahi (pepa ma). I hinga a Tiamana i te whakamutunga ki te United States, mo te kaute iti, 1: 0 (ko te whaainga a Kealia Ohai). I whakaingoatia a Benkarth hei kaitiaki whaainga pai rawa atu o te whakataetae me te "Golden Glove". I te Oketopa 2012 i tohua a Benkarth mo te tiima a motu mo te wa tuatahi. I tae atu ki te 28 o Hurae 2013 i karangahia ia mo te UEFA Women's Euro 2013 i Sweden, hei whakakapi i a Kathrin Längert i te roopu.
