Meyer retained the squad that played Argentina in Mendoza at the weekend but has been given permission to add fullback Zane Kirchner and hooker Chiliboy Ralepelle to the side.
Ralepelle, who was not taken to Argentina due to injury, will have to pass a fitness test before boarding the flight to Brisbane where South Africa will play Australia on Saturday week.
"This will be two tough weeks on the road against two of the best sides in the world," Meyer said.
"We say last weekend against Argentina that we still have a lot of hard work to do.
"Australia may have lost their first two matches of the Championship, but they showed a marked improvement in Wellington last weekend."
Meyer said Australia were always tough at home and South Africa's last win in Australia was in 2009 while over the years they had won only three of 18 Test matches in Australia.
"We let ourselves down in certain areas of the game in Mendoza and will have to fix those if we are to be competitive against Australia," he said.
South Africa's squad for the tour is: Backs: Bjorn Basson, Jean de Villiers (captain), JJ Engelbrecht, Bryan Habana, Zane Kirchner, Patrick Lambie, Willie le Roux, Ruan Pienaar, Jan Serfontein, Morne Steyn Piet van Zyl, Jano Vermaak.
Forwards: Lourens Adriaanse, Willem Alberts, Marcell Coetzee, Bismarck du Plessis, Jannie du Plessis, Eben Etzebeth, Siya Kolisi, Juandre Kruger, Francois Louw, Tendai Mtawarira, Coenie Oosthuisen, Chiliboy Ralepelle, Guthro Steenkamp, Adriaan Strauss, Flip van der Merwe, Duane Vermeulen.
