Glory are set to face Usuthu at Mbombela Stadium tomorrow, before taking on Dikwena on Friday and the Clever Boys on August 31.
The Australian team were coached by current Bloemfontein Celtic technical director Mich D'Avray from 2001-04. D'Avray led them to their first NSL Championship in 2003, which the club defended under him in 2004.
Glory visited South Africa last year, when they lost 2-0 to Celtic, and 1-0 to Platinum Stars, before beating AmaZulu 3-1.
Speaking in an interview with KickOff.com, club coach Ian Ferguson says he is looking forward to an exciting few games.
"We are happy to be back in South Africa. The time we were here last year we enjoyed ourselves and that's the reason we are here again.
"I understand [PSL teams] have about four weeks doing their pre-season, and we have just started which I believe that will give us strong opposition.
"We lost 1-0 against Platinum Stars but beat AmaZulu 3-1 and we look forward to very good games against both teams as they are quality sides."
The game between AmaZulu and Perth Glory will kick off at 6pm at Mbombela Stadium tomorrow, with a R20 entrance fee for soccer lovers who wish to see the game.
