The Sixers will be determined to secure their third consecutive WBBL title when they open their campaign against the Melbourne Stars on December 1.
However, Perry admits it will be no easy task for the Sixers to defend their crown given the strength of the competition.
"Every year I think the competition grows and develops and certainly last season there wasn't an easy match in the tournament," Perry said.
"Every team has got to improve and I don't think we're any different."
Perry believes the Sixers will benefit from the having the core of their WBBL|03 Championship winning squad on deck again in WBBL|04.
"It's really nice to have pretty much the same group as last year and a stable group that knows one another well," Perry said.
"Hopefully there are some really great challenges for us to continue doing everything a little bit better."
The Sixers are scheduled to face local rivals Sydney Thunder at North Sydney Oval on December 8, before the return fixture at Spotless Stadium on January 2. Perry says she has already circled both dates on her calendar.
"The crosstown rivalry with the Thunder is something we always look forward to," Perry said.
"Besides the Finals, they're the biggest games for us each season and so far they've delivered some really great matches too.
"We know all the players so well, so it's kind of like playing your sister. I'm really looking forward to those matches as we do every year."
