Ann: Quarterly Activities/Appendix 4C Cash Flow Report, page-11

Aus launch is symbolic for 2 reasons -
Global launch will start with Aus, so anything they pick up with our rollout will be replicated in other regions. Add to that the success of the Aus launch could be seen as a precursor to the success of similar OS markets.
DOU is based in Sydney and New York, it makes sense to establish the business here after the US where the dual HQs are located. The news will create positive sentiment on the market here as local investors like to see a company operating on home soil as it decreases sovereign risk.
I give zero credit to the idea of DOU folding within 12 months due to lack of capital. The high cash burn will need to be addressed to keep some respectability with instos (if that's still possible)
