I think your assumption is incorrect. I have been keeping an eye on EV professionals in Australia for about 4 years now. I have not seen any sign of any EV shops in Melbourne (assuming you are excluding retail like Tesla). Sorry for the bad news.
I live in Vic and NOTHING EV is avaliable in Melbourne . Its a disgrace, and I'll also put it out there that EVWorks in WA are hopeless to deal with .
I sourced most of the parts for my EV conversion from eBay and Alibaba because dealing with locals is impossible . I even got stuff from NZ . Though Neale at Milbay.com.au where I sourced my LiFePo4 batteries was great to deal with , again in QLD , there is just nothing in Vic .
The motor temp thermister still dosen't work. Ive added an external temp gauge.
Ive discussed the EV Works issue with HPEVS and they suggested I become a vendor & east coast dealer. Certainly an opening there for somebody.
Its all I can do to stop swearing about the stumbling blocks for DIY EV converters in this country. And with the bloody Turnbull government adding GST & excise to online purchases over a $1000 in July , its just getting harder.
