Hi all - late to the game here. Three mates and myself bought CBR last year via Commsec - we have now opened Westpac trading accounts as we heard Commsec were not able to assist. Can we get some advice on how to proceed? This 28 page document is overwhelming for 4 blokes who saw an interesting business kicking off in Geelong!
What 'Chapter 4 Status' do Aussies have?
Any other tips on filling out the actual document?
My mates bought in their own names - I also bought through the family trust trading account to make things even more fun - took 4 visits to Westpac to get the account open!!
Confused as.
TIA
