Peter Siddle has claimed the final spot in Australia's XI for the first Test against South Africa, with the veteran's experience giving him the edge over Joe Mennie.
Skipper Steve Smith has confirmed his side for the clash that starts on Thursday in Perth, with Mennie named 12th man.
Uncapped right-armer Mennie will play for South Australia in the Sheffield Shield before linking up with the squad in Hobart for the second Test.
Siddle, after spending most of the year recovering from stress fractures in his back, proved his fitness last week in the opening round of the Shield season.
"They're both bowling well," Smith said of Siddle and Mennie.
"They're the sort of bowlers who can bowl consistent areas, keep the runs down. I guess it complements the other guys.
"We've gone with Sidds on this occasion and it's good to have him back after a fair injury layoff."
Siddle is the most-experienced member of Australia's squad and has played 12 Tests against South Africa.
"A bit of experience," Smith said, when asked why the Victorian received the nod ahead of Mennie.
Mitchell Starc, who will bowl with a 1cm open wound in his leg, and Siddle are both short of match fitness.
But both have impressed teammates with their pace this week in the WACA nets.
"They're quite fresh so they might be able to sustain things a little bit longer than maybe the medical staff would like them to," Smith said.
"They're fresh and ready to go."
