Other teams she played for were Sliedrecht Sport, Cornix Schelle (Belgium) and AMVJ.

She started her international beach volleyball career in 1997, playing tournaments around the world with her sister Debora.

They also participated at the 2000 Summer Olympics, where they lost both of their matches, eliminated in the second preliminary round by Lina and Petia Yanchulova, also sisters.

Kadijk's next partner was Merel Mooren and, like Rebekka's earlier teams, Kadijk/Mooren were nearly unbeatable in their own country.

In 2007 they won the final of the German Masters in Hamburg, their first European Tour Tournament win.
