The 26-year-old is part of a 34-player squad that will take part in two camps and compete in Europe before the Olympic team is announced in August ahead of Rio de Janeiro next year.
�I found out about two weeks before the end of the (Waves) season,� Tomlinson said.
�The fact that I was coming back from injury gave me the biggest boost because I really wanted to play.�
The Melbourne-raised basketballer, who joined the Waves in 2014, suffered ligament and tendon damage to her ankle in a match against the Dandenong Rangers in December.
�The doctors said they weren�t sure if I�d be back so it was pretty scary,� Tomlinson said.
�This year is the qualifier for the Olympics so that�s my goal.
�I�m pretty excited. I�ve never been picked in the squad but I do have experience playing college basketball in America and in Europe so I can use that experience to help me.�
Olympic medallist and former Women�s National Basketball Association player Lauren Jackson is also part of the Opals squad.
�I said to my mum the other week that I couldn�t wait to play with the best players in Australia, it will be a great experience,� Tomlinson said.
The only Western Australian in the squad, Tomlinson is playing for the Willetton Tigers in the State Basketball League this season.
