Renegades have become one of the oldest lists in BBL history with Siddle joining Nathan Lyon (35) as a new signing. Renegades already have three players over 35 - Shaun Marsh (40), Aaron Finch (36) and Jon Wells (35).

"We've made a concerted effort to add more experience to our playing list this off-season, so to welcome 'Sidds' back to the Renegades, alongside the additions of Adam Zampa and Nathan Lyon is a fantastic result," Melbourne Renegades General Manager James Rosengarten said.

"Sidds is well respected not just for his contributions with the ball over a long period of time, but for his leadership, tactical awareness and broader knowledge of players and the T20 landscape.

"He has plenty of existing relationships within our playing group and we know he will be an important contributor for us not only on the field but with all the other attributes he brings that help build successful teams."

Siddle was thrilled to be back in Melbourne having also moved back to Victoria in domestic cricket after three seasons with Tasmania.

"I'm excited to be returning to where my Big Bash journey started and to be back in red this year," Siddle said.

"I've loved my time in Adelaide over the last six seasons. But it's time for a new challenge, and I'm looking forward to reuniting with some good mates of mine at the Renegades.

"Looking at the playing list that's being assembled, there's no reason we can't challenge for the title this year.

He instead joins the Stars to bolster their bowling stocks alongside the off-season signings of Scott Boland and Joel Paris.

"We identified Mark as a target to further strengthen our fast-bowling stocks and we can't wait to see what he can do at the MCG," Melbourne Stars General Manager Blair Crouch said.

"He has been a consistent wicket-taker in the BBL over a number of years now and he'll bring a lot of valuable experience and cricket IQ to the group."
