Webb joined the Renegades ahead of the WBBL|04 season and the new contract ensures she’ll remain with the club until at least the end of WBBL|08.
“Moving to the Renegades has really helped fast track my development,” Webb said.
“I’ve been given some opportunities to establish myself in the middle order and I’m really aiming to take my game to a new level in the coming seasons.
“We’ve got an exciting group of players coming through and we’re all looking forward to working under the leadership of Soph (Molineux) and ‘Helmo’ (Simon Helmot) as we try to push for a finals spot.
“I love being around this group, I highly value playing with a lot of good friends and I’m looking forward to continuing with this core group over the coming seasons.”
Webb made 246 runs at an average of 30.75 last season, including an unbeaten 54 from 33 balls in the Renegades super-over win against the Melbourne Stars.
The 21-year-old played every match for the Renegades in WBBL|06.
“Courtney is a key part of our future who has impressed everyone with her composure out in the middle,” Renegades Coach Simon Helmot said.
“She came in at some difficult times last season but held our innings together and we’re excited to see Courtney’s development over the next couple of years.
“Courtney is a great example of someone who has worked hard, earned an opportunity and then grabbed it with both hands.
“She’ll play an important role in our batting order this season, she’s got some skill with the ball and as we saw from her catch off Ellyse Perry last season, she’s an elite fielder.
“With that all round skillset Courtney has the tools to be a leading player across the competition for many years to come.”
