In short. Do date Jin is generating their revenue within Australia as a reseller of lottery tickets.
And selling them with quite a handsome margin. Overseas markets have a far stronger competition in place and do work on a high volume low margin business. Jin will only be a small fish in a very big pond.
Within Australia Jin is facing an increased competition from Tatts, who started selling online tickets in Victoria two years ago and in NSW last year. Qld Golden Gasket is run by Tatts only, and Jin has no agreement with Tatts in that state.
WA state lottery is in the hands of Intralot and hence very little chance for Jin doing business there.

I would like to draw your attention to the fact, that the reseller agreement with Tatts for Vic is running out in a few days time and for NSW by the end of the year.
Interesting times ahead:-)
