2 Way Sumitomo HM Series Female Connector Housing - automotiveconnectors.com
Might need to try and get someone in the UK to send some connectors across to Aus in future... not easy to find here
Housings - automotiveconnectors.com (has HM housings in 2 and 4 pin)
(4 pin male MT and HM connectors can work with either female version, but 2 pin MT and HM are different shapes )
