Callun - give AFFT a call (02) 9666 9222 and see if the could recommend anyone over in Malaysia or in fact whether or not they could arrange the actual freight.
Another company I could think of is APC Logistics -
http://www.apclogistics.com.au/share...sbane&office=4 there's all the numbers for their Brisbane office (assuming you're from Brisvegas).
One that I know people have dealt with but they're only customs brokers but should know something - (02) 9316 5744.
As a reference, a 20ft from Hong Kong to Sydney cost $880-1200USD (depending on season, it's peak right now) so I wouldn't expect it will cost much more than that ex-KL or anywhere in Malaysia. However, I got a funny feeling it might need to transit Singapore to make its way here. Port charges are pretty expensive so you'll be looking at another $1k USD to cover all the port charges both here and Malaysia plus transport the actual container in from your family home to the port and from the port in Bris could be another biggie. Good luck.
