The easiest way to participate in an IPO is to contact the company and apply via their Prospectus or they may direct you to their lead manager who is managing the IPO.   All the details will be included in the Prospectus such as Issue Price, Important Dates and the ability to send your allocation to your existing ThinkMarkets HIN.  Note: If you do not quote a HIN or the name and address details does not match exactly with your ThinkMarkets registration details with the details of your application, any allocated Shares issued can be held on the Issuer Sponsored subregister and not on your HIN. Once the Company is listed and trading in the ASX, you can then buy or sell your shares using the ThinkTrader app.
