Siddle, who was contracted to the Melbourne Renegades last year, missed all of BBL|06 after being sidelined with a back injury suffered in Australia’s Test series against South Africa.
But after an uninterrupted pre-season, the 32-year-old hopes the extended lay-off in combination with the move to the Strikers could help him add to his already glittering international career.
"Just getting back out playing, that's the thing I've missed so much," he said.
"The injury has been tough, but I think that time off might have just given me a new lease of life and some longevity at the back-end of my career.
"Getting those early games in for Victoria at the start of the season and then getting over into the Big Bash for the Strikers will hopefully propel me up the ranks and get me back into the Australian side."
Siddle has captured 211 Test wickets in his 62 matches.
Strikers coach Jason Gillespie said Siddle would offer valuable experience to the squad, on and off the field.
“We feel we’ve just got a great coup in Siddle and he adds considerable depth,” he said.
“He’s also a great guy and we’re really looking forward to him playing an important role in the next few years.
“We’ve got a bowler with experience, not huge in T20 but we feel he’s got the transferable skills and his presence around the team is something that you can’t really put a measure on.”
Siddle played the first Test last summer against South Africa in Perth to take his career total to 62 matches. He ranks 14th on Australia’s all-time Test wicket list with 211. He also has played 17 ODIs and two T20s for Australia.
