I've been a Commsec client since 2001 and am happy with their features and services.
Maybe have a browse around their website
https://www.comsec.com.au/ if interested.
If you nominate them as your CHESS sponsor and open up a Commonwealth Direct Investment Account (CDIA) to settle your trades you then qualify for their internet preferred brokerage rates which are $19.95 for orders less than $10k, $29.95 for orders $10k - $25k and 0.12% for orders more than $25k
Commsec also offer free basic charting, free basic research and fundamental data and forcasts. They also offer conditional orders.
Anyway, all of the above info and more is on their website. You can even apply online to set up an account.
