my assumption is that you remain with eSuper but you are switching from eBroking to Commsec because you want to buy and sell internationally?

my assumption is that this is allowed by eSuper

my sympathies it sounds like a complex bind that will tie you up for a month, cause more grey hairs and have you wondering privately whether a SMSF is the way to go.

l have not had that exact issue but have familiarity with the stress of SMSF changes when things don't go as planned. it is incredibly stressful, l did find the opposite Commsec were helpful.

possible (unpopular solutions)
1. don't trade shares internationally use ETF's and Hedge Funds instead
2. change the SMSF structure from Trustees to a Company (if commsec are happy with that?)
3. if permissible check with other brokers
4. ask Commsec what would solve the problem
5. there is a financial complaints department (l forget their name) and they can escalate the issue.

As we age we are often told by lawyers and accountants to adopt a company structure.
