Ann: Shareholder Support and Instructions, page-71

from commsec:

"We do not currently allow any buy orders for microcap securities on your CommSec International Shares Account. U.S securities that were purchased on a CommSec International Shares Account which fall below the microcap thresholds can still be sold but may incur restrictions requiring additional documentation prior to accepting sell orders.

Any securities transferred to CommSec that subsequently become a microcap cannot be sold. Exceptions may be considered if appropriate documentation can be provided and accepted by our International Custodian."



You can't purchase new IXHL shares and I'm fairly certain you won't be able to sell using commsec unless you get a special exception from the international custodian, whoever that is
