There has been considerable discussion about this topic, and as has been stated elsewhere, is what I have done for year but using a Financial Advisor account which is not available for regular retail traders.
The alternate answer is using a Friends And Family (FnF) Master structure. Follow these instructions from Neil Swanson, head of IB Australia:
You need to open the master in a personal name (i.e Neil Swanson not a company name as no longer accepted for FnF master) as this is purely an allocation/header account, not a trading account.
Also, they can only have Friends and Family under the master and are unable to charge fees.
Any client with an existing IB account can open the FnF master and then following they can link up their existing IB account(s), note the master must have all privileges (trading configuration/permissions) as the client accounts for the linking to be accepted.
Please have them use the below instructions application link to open a FnF master. You can send this email to all your students to simplify if easier also.

Ensure to select: ‘Salesperson’ then ‘Neil Swanson’ on the 2nd section of the application when asked:
1) How you heard of IB
2) Who helped you with your account application
This will ensure you have an Australian representative on the account and enable me to assist you going forward.
Neil deals with insto clients only so if you have any queries send them back through here and I will pass them on.
