The word 'expert' was
NEVER used. The word '
PRACTITIONER' was used -- a well educated martial arts PRACTITIONER.
A practitioner is someone that merely 'practices'. If there was a martial artist expert involved, I am sure that word expert would have been used instead of practitioner.
Stop narrowing the focus down to one form of martial arts. Have a look at the various forms of martial arts. I'd be checking out the martial arts connections to WA University given that the martial arts
practitioner was also described as
well educated. Here is a link that will take you to all 'sports orientated' clubs associated with UWA Sports for 2015. I note there are
7 such arts that are described as martial arts. The UWA has a specific venue named UWA Martial Arts Centre and all of these 7 listed on the UWA website practice out of the UWA Martial Arts Centre.

I would also be considering what martial arts were popular (in Western Australia) between say late 1980s to mid 1990s -- given the person worked with Sarah and was well educated, a Uni degree would take several years.
Look for someone THAT WORKED CLOSELY WITH SARAH SPIERS -- she worked for BSD Consultants; they were based at 2 Bagot Road Subiaco immediately opposite Kings Park. Given that police detectives obviously looked very closely at an individual Sarah worked with -- and found enough for them to include information about this individual in the CIA documentary, I would perhaps be checking to see if someone 'took flight' from BSD around 1996. Look for somebody that perhaps had a small child in 1996 and that is why he perhaps had MET JANE RIMMER ONCE -- through the child care centre. Look at the sports that Jane Rimmer used to follow ie football and hockey -- Ciara had also been involved with hockey. Was Sarah ever involved in hockey personally, or did she know someone that was ?
The person you refer to on here NEVER worked closely with Sarah Spiers. Simple as that. Sarah Spiers was a secretary -- did this work involve working with a group of people or did her work involve secretarial support for only one person ? I have always found when comparing Sarah with her sister Amanda, that their physical appearance was almost identical. Amanda attended Uni and I believe completed a teaching degree. Was there anyone in her background that could be responsible ?
This link will give you an idea of what BSD Consultants used to do
