Ricky Ponting will lead Australia at the World Twenty20 after his wife recovered from a health scare.
Ponting did not fly out to South Africa with the rest of the squad, instead remaining at home with his ill wife Rianna.
However, the 32-year-old is now expected to fly to Johannesburg and join his team-mates in time for the start of the competition.
"Fortunately Rianna's health has improved over the last few days and I'm hoping travel plans can be finalised as soon as possible," he told tvnz.co.nz on Friday.
"I'm grateful for the support we've both had from Cricket Australia and my team-mates. It made things easier here knowing the team was in such good hands.
"With things on the improve, Rianna and I are both keen that I now focus on the job at hand with the Australian team."
Australia received another boost going into the tournament with the news that all-rounder Shane Watson is fit to play.
Media Manager Lachy Patterson said: "Shane has recovered sufficiently from the hamstring injury he sustained training in Brisbane last Sunday to join the squad in South Africa."
Paceman Stuart Clark has also arrived in Johannesburg after attending to his sick son.
Australia begin their Twenty20 campaign against Zimbabwe in Cape Town on Wednesday September 12.
