As far as I know, the IIc+ was never released outside the USA.  It was
certainly not available in New Zealand, and probably not in Australia
either.

It was released in 1988.

The major differences between the IIc+ and earlier IIc:

- the IIc+ has a built-in 3.5" drive (400k/800k, compatible with the
Apple 3.5 Drive) instead of a 5.25" drive.  You can connect another
external 3.5" drive and/or two 5.25" drives.

- the IIc+ has a built-in accelerator, which runs the processor at 4
MHz.  In effect, this is identical to a 4 MHz ZIP CHIP being built
into the machine.

- the IIc+'s serial connectors are Mini-Din-8's instead of DIN-5's.
They are partially pin-compatible with the Mac and IIgs, but the same
signals as the IIc are provided (one flow control out, one flow control
in) and the same serial chip is used, so the IIc+ doesn't support
higher baud rates, proper hardware handshaking, or a LocalTalk
connection (the same as the IIc).

- there is a memory expansion connector inside the computer.  I don't
know if any cards were ever made to work with this. 

- there is a modem expansion connector inside the computer, which
overrides the second serial port.  I don't think anything was ever
made to work with this.

- the mains supply is built into the computer instead of requiring a
separate "brick".  The main disadvantage of this is that you cannot
power the IIc+ from an external DC supply such as a car battery.
