There appear to be only two bus prototypes, one urban and one coach. It's
not clear whether they are both here in Australia or in China:

There are too many design compromises on the urban bus to make it
acceptable. In terms of competition they would be rolled by Chinese imports
anyway. The only electric urban buses running in Australia so far are from
China, with the exception of two prototypes from Bustech in Adelaide which
they never seem to have got on the road after two years.
