Hi Bro, Yes i am intending to come back, haven't figured out yet if i would be continuing my career in Telecom or setup some business, i think after working in Australia i will not be able to fit in Pakistani work culture again so private business will e the way to go, Want to do something related to cars, that's the only other thing i know besides Telco 
Yes you are right about verifying documentation for vehicles sold at auction, it was a pain verifying and registering my eg hatch back in 2010. it was an embassy auction. i believe things would have improved a bit since but from your comment it seems its all the same the way i left it 11 years ago
