Suggest you ask around at Archerfield in Brisbane - there is at least one that has appeared at Airshows at Archerfield and throughout SEQ which would suggest it is based around the Sunshine/Gold Coast area or Darling Downs/Brisbane.
I last saw it about 15 months ago - bright blue and yellow - all set up with the frames etc for wing walking.
I know it did operate out of Toowoomba at one stage as a friend of mine tried it out to see if it was "as easy as it looked" - apparently it wasn't!!
Good luck and let us know if you find it. Would try asking around Archerfield and Toowoomba.
