The Canberra Capitals star joins teammate Keely Froling in Australia's three-on-three squad for the final Olympic Games qualifying tournament to be held in India following the WNBL finals.

An injury to Alice Kunek has opened the door for Griffin as Australia prepare to meet 19 teams vying for a top 3 finish to book a place in an eight-team tournament in Tokyo.

It perhaps looms as Griffin's best chance of competing at the Games with Leilani Mitchell likely to assume the one naturalised player slot for the Opals.

"The more I think about it, the more I think three-on-three is probably the right fit for me," Griffin said.

"They've continually asked for my interest and said my game would really excel in that format. That might be the better fit for me personally.

"It feels really good to be named in an Australian squad. I guess I've got a decision to make here, whether to do three-on-three and fully focus on that, or whether to keep pursuing the Opals.

"In order to do something at the top level in the world like competing in the Olympics, you probably have to dedicate yourself to one thing or the other. I've got a big decision to make.

"I've only shot a three-on-three ball like twice. Basketball is basketball, there will be little nuances and strategies.

"I'm a student of the game though, so with enough game footage and a coach and teammates around who want to get me up to speed, I'll be alright."

Australia has been placed in group B, along with Iran, Japan, Ukraine and Turkmenistan. They open their campaign against Japan on March 18 before the finals take place on March 22.

Griffin and Froling won't be the only ones facing a hectic end to the WNBL season with Bec Cole (Southside), Maddie Garrick (Melbourne) and Lauren Nicholson (Adelaide) juggling Olympic qualifiers with WNBL playoff tilts.

The Capitals duo will lock horns with Garrick's Boomers in game two of their semi-final series at the State Basketball Centre on Sunday.

A win would send Canberra back to the grand final while a loss would force the series to a decider at the AIS Arena on February 26.

"Definitely a little bit excited thinking about [the road to Tokyo], and also a little bit nervous," Froling said.

"For now my mind is definitely on the finals, and that's just in the back of my mind. As soon as that finishes, that'll be the next thing I'm thinking about.

"With finals running all the way up to it and heading overseas. It will be hectic but it's fun, and it's why we play basketball."
