Ok, well depends on what u wanna do with thai. Melb martial arts on Flinders has both, but if ur lookin to fight thai, this is not the best place. It's more class format, teaches the techniques, has oportunities for amateur fights, but thats about it. Dominance (i think) caters for both in richmond with benny smullens. Also try Powerplay in brunswick, joe nader's gym. Finally, if thesee dont suit, Sityodtong is great, but only thai. That in brunswick. Same deal with JTS in richmond. Best to do something with bjj, coz thats the direction the fight scene is heading, with ufc, and mma fights.
Good luck, hope it helps! : - )
